wilms tumor vs neuroblastoma radiology

Radiographics. If this mutates, which can be signalled by abnormal amplification, cancerous cells can develop and the resulting mass is more resistant to treatment, thus it has a more unfavourable outcome [1]. Thickening and irregularity of these lines, in particular the right paraspinal line which is not normally seen in healthy children, can indicate the presence of increased mediastinal soft tissue and this warrants further investigation [7].

Department of Radiology, Great Ormond Street Hospital for Children, Great Ormond Street, London, WC1N 3JH, UK, Maureen Dumba, Noorulhuda Jawad & Kieran McHugh, You can also search for this author in Note erosions of the posterior 3 Cancer Imaging. Alterations in two chromosomes, namely a deletion on the short arm of chromosome 1 (1p) seen in around a quarter of NBLs, and deletion of chromosome 11q have a poorer prognosis [1]. J Postgrad Med Edu Res. We also searched the reference lists of articles identified by this strategy. doi: http://dx.doi.org/10.1016/j.ejca.2011.05.025. Preliminary evidence suggests absence of IDRFs leads to more complete resection, with the presence of IDRFs resulting in more post-operative morbidity [16]. MRI can easily assess the extent of disease, being superior to CT in assessing metastatic marrow disease, chest wall invasion and spinal canal involvement [Figures 3, 4 & 5]. Origin: Embryonic nephrogenic (mesodermal) cells Mechanism: Deletion of WT-1 gene on chromosome 11 Pathology: a. Macroscopic (Gross): large, solitary tan to grey color mass; pale on cut section with areas of hemorrhage; 10% are bilateral or multicentric; grossly difficult to distinguish from neuroblastoma Radiographics. Ora I, Eggert A. Nephroblastoma, also more commonly known as a Wilms tumour, is the commonest renal tumour in childhood and more typically presents as abdominal pathology with few constitutional symptoms, although rarely haematuria can be a presenting feature. However, the role of chest CT is not controversial in patients who post-operatively are found to have unfavourable histology or stage III disease, as accurate staging at diagnosis appears to improve overall survival in these patients [28]. 2016;34(1):13-23. 2010;75:321–8. Considering these factors with new presentations can be helpful with early management strategies, and in initial discussions with a family who have a child with a newly diagnosed malignancy. The goals of modern pediatric oncology reflect both of these facts. Axial CT of a 3 year old boy with right-sided Wilms tumour, again demonstrating the ‘claw sign’ (blue arrow). doi:10.1200/JCO.2008.16.6785. Results.

Vascular invasion is estimated to occur in approximately 5-10% of cases [24]. Neoadjuvant chemotherapy is useful to shrink tumour size prior to surgery, but European (SIOP) and American application of this differs. Progressive Supranuclear Palsy (PSP) (Syn : Steele-Richardson-Olszewski Syndrome) Adult onset neurodegenerative disorder. ribs indicating a posterior mediastinal mass. We invited one expert on state of the art Wilms tumour treatment from each discipline (surgery, pathology, paediatric oncology) to join the writing group. Radiotherapy is indicated for local stage III, so down-staged patients avoid this and the long-term post-radiotherapy sequelae. volume 15, Article number: 5 (2015) Here we review the literature related to cancer energy metabolism in neuroblastoma (NB) and Wilms tumor (WT). 2000;175(2):477–83. Both neuroblastoma and Wilms tumor occur in early childhood and typically present as large abdominal masses closely related to the kidneys. doi.org/10.1016/j.ejrad.2010.05.041. Plain abdominal radiographs are non-specific for Wilms tumours. On MR at diagnosis, the tumour tends to return low signal on T1-weighted sequences with high signal on T2 [3]. Assessment of risk pre-surgery was recently deemed to need better defining, with now more reliance placed on pre-operative imaging [8,9]. The Florida Cancer Data System was queried from 1981 to 2004. Tumours of the chest and neck can be incidentally picked up on radiographs performed for other reasons [Figure 1]. Google Scholar. Neuroblastoma (NBL) is the most common solid extra-cranial tumour in childhood [1]. MIBG scintigraphy showing avid uptake at the site of the abdominal NBL with widespread bony metastatic spread.

The surgical approach in bilateral disease aims to spare any normal renal parenchyma where possible. J Nucl Med. Cancer Imaging 1998;18(4):947–68. Chronic Inflammatory Bowel Disease 2. This paper reviews the clinical aspects and imaging characteristics of both tumours, summarising the key differences to aid the paediatrician and radiologist in their diagnosis and management. They can demonstrate extension across the midline and into adjacent body cavities. Results of the SIOP 2001 study. Presentation is usually with a large, painless abdominal mass and very little in the way of constitutional symptoms [20]. The INRGSS has 4 simpler stages of disease summarised in Table 2 [13,14]. doi:http://dx.doi.org/10.1148/radiographics.18.4.9672980. 2011;253(5):1004-10. 123I-MIBG Scintigraphy and 18 F-FDG PET in Neuroblastoma.

They often grow to a large size before causing problems, so a palpable mass on presentation is common. Correspondence to The Vaginal and perivaginal cysts include  1. NBLs can metastasize to the skull base and orbital floor resulting in periorbital ecchymoses and a so-called “raccoon eye” appearance [1,3]. PubMed Central  Under the microscope, they are small, round, blue cells that are clustered in rosettes. These features are particularly important when the mass is known to be encasing major vessels. In children with bilateral disease, the therapeutic approach and philosophy are very different. The peptide binds to somatostatin receptors and can, therefore, be used for diagnosis and follow-up [10]. Renal preservation surgery becomes paramount. Low risk patients with local tumour masses should have them surgically resected. Post-treatment surveillance for bilateral disease should be with MRI and not CT to reduce the radiation burden in these children the vast majority of whom have a good long-term prognosis [27], but some institutions may image post-operatively with CT at the surgeon’s request. Smets AM, van Tinteren H, Bergeron C, De Camargo B, Graf N, Pritchard-Jones K, et al. Hiorns M, Owens CM. doi:10.1016/S0140-6736(07)60983-0. BACKGROUND. Eur Radiol. Nephroblastoma, also more commonly known as a Wilms tumour, is the commonest renal tumour in childhood and more typically presents as abdominal pathology in an otherwise asymptomatic patient. Monclair T, Brodeur GM, Ambros PF, Brisse HJ, Cecchetto G, Holmes K. The International Neuroblastoma Risk Group (INRG) Staging System: An INRG Task Force Report. Abdominal masses usually cause pain due to their mass effect, as well as abdominal distension [6]. PubMed Google Scholar. FDG combined with CT, PET-CT, allows for more accurate localization of disease. 2009;50(8):1237–43. After hydronephrosis and multicystic dysplastic kidney, it is the most common cause of a renal mass in a child [19]. Clin Radiol. Lancet. Neuroblastoma and Wilms' tumor are the most common noncentral nervous system solid tumors in children. •Tumors may occur anywhere along the sympathetic chain within the neck, thorax, retroperitoneum, or pelvis, or in the adrenal gland. Radiology of neuroblastoma in paediatrics. Dahnert W. Urogenital tract. Thoracic NBL may present with airway compromise, scoliosis or as an incidental finding on chest x-ray. An important consideration with pediatric abdominal mass in distinguishing a Wilm's tumor from neuroblastoma, the chief differential in a child of this age. International Society of Paediatric Oncology Europe Neuroblastoma, International Neuroblastoma Response Criteria, International Neuroblastoma Staging System, International Neuroblastoma Risk Group Staging System. Accurate staging, especially the presence or absence of nodal disease, is vital in Wilms tumour to ensure appropriate management pathways are adhered to [23]. Article  Coronal T2 MR of a 2 year old boy showing left-sided NBL mass with bone marrow involvement (blue arrow). 2008;18:3. doi: http://dx.doi.org/10.1016/j.paed.2007.12.003. Google Scholar. Neuroblastoma is a neuroendocrine tumor that usually develops in the adrenal glands, but can develop in any neuroectodermal tissue. Variable contrast-enhancement may be seen, with the more malignant tumours showing restricted diffusion on diffusion-weighted imaging (DWI). Cytoreductive therapy 3.

Also, it is a post-surgical staging system and is thus dependent on the expertise of the local surgeon. It can, however, be acquired in a 3D format with the resultant Single Positron Emission Tomography (SPET or SPECT) images providing more detailed information. Renal vein thrombus may be more difficult to evaluate or exclude with US, and CT or MRI tend to be easier to interpret in this setting. It may also appear less commonly as a solid spherical mass [19]. Foci of nephroblastomatosis may be small cystic lesions, hyperintense on T2W but sclerotic nephrogenic rests may appear fibrotic, being relatively hypointense on T2W sequences. Treatment of Wilms tumour is hailed as one of the greatest success stories in modern oncology. 2001;21:217–28. ... Neuroblastoma •Arise from cells of the neural crest that form the adrenal medulla and sympathetic ganglia. Paraspinal tumor may invade the spinal canal via extension through adjacent neural foramina is s/o NB. Imaging neuroblastoma: what the radiologist needs to know. Neuroblastoma and Wilms tumour are both relatively common abdominal childhood cancers. Chest x-ray of 3 year old girl showing thoracic NBL. This showed promising early results as a feasible agent in a select patient cohort [11]. The COG stratify risk as low, intermediate or high based on prognostic factors and the INSS staging system. Occasionally, however, a neuroblastoma appears to be intrarenal. 2009;27:289–97. 2012;58(4):551–5. 2011;261(1):243–57. 2012;59(1):247–67. Introduction. N Neuroblastoma commonly crosses the midline and usually calcifies. J Clin Oncol. It is a little more prevalent in people of African descent. There are slightly higher local relapse rates reported in SIOP studies, but these radiotherapy naïve patients do appear to have high salvage rates [29] The American approach is initial surgery and then chemotherapy after post-surgical staging. PubMed  Like CT, MRI can also readily demonstrate the ‘claw sign’ of normal renal tissue around the tumour [Figure 10]. doi:10.1102/1470-7330.2011.9008. The vast majority of cases are sporadic. doi:10.1007/s003300100931. This type of tumours are characterised by the proliferation of immature cells that are usually only seen in the developing embryo. Taupathy. TrkA is a neurotrophin receptor that may actually be associated with an improved prognosis. Ann Surg. For patients with unilateral Wilms tumour with lung lesions only visible on chest CT, not seen on plain chest radiographs (but deemed metastases and treated as such), their overall survival and event-free survival was no different to those patients whose lung lesions were not deemed metastatic [28]. The management of synchronous bilateral Wilms tumor: a report from the National Wilms Tumor Study Group. This is thought to be secondary to a reduction in mitosis [1]. Lonergan GJ, Schwab CM, Suarez ES, Carlson CL. Understanding the principles in management of Wilms tumour: Can imaging assist in patient selection? Both neuroblastoma and Wilms tumor occur in early childhood and typically present as large abdominal masses closely related to the kidneys. This negative feature occasionally includes those children who otherwise have favourable tumour presentation features, for example 4S/MS disease and young age [1]. Wilms Tumor and Neuroblastoma Hamzeh Halawani M.D. Wilms' tumor provides a spectacular example (Fig 1). High-risk patients have a more intensive chemotherapy course followed by resection then myeloablative chemotherapy [16]. NBLs have a variable prognosis; tumour stage, patient age, tumour oncogenes and DNA content are all known to be implicated. In 2002, approximately 15% of childhood cancer deaths were due to NBL [6]. Radiology. 2007;369:2106–20. Conventional radiograph of abdomen shows a large right upper mass displacing bowel loops into the pelvis and across the midline (blue arrows). The pathophysiology and clinical aspects of both tumours including associated risk factors and pathologies are discussed. Features that are suggestive of thoracic disease include abnormalities of the normal silhouettes typically seen on chest x-rays.

Mesoblastic nephroma occurs in the neonate whereas Wilms tumor is very rare in the newborn. Although 1p deletion is associated with MCYN amplification, 11q is not correlated and appears to have separate negative prognostic factors. 2000;20(6):1585–603. Isovolumetric sequences, allowing reconstructions in other orthogonal planes, can be particularly helpful with bilateral disease [Figure 11] when renal preservation surgery is the operative strategy. The International Neuroblastoma Risk Group (INRG) Classification System: An INRG Task Force Report. 2012;48(7):1060–5. Over 90% are MIBG-sensitive, but for those primary tumours that are not MIBG avid, 99mTc-diphosphonate bone scintigraphy is currently recommended to look for bony disease [1]. In children, the paraspinal lines are less frequently observed than in adults due to less mediastinal fat and no aortic ectasia. Typically, NBLs occur in early childhood with up to 90% diagnosed by 6 years of age [4]. Although yet to be conclusively shown to be superior to CT, the preferred imaging modality at diagnosis is now without doubt contrast-enhanced MRI, in these children with such a favourable long-term outcome. doi:10.1002/pbc.24757. 2009;27(2):298–303. These are the CT Brain images of a young male patient, who had h/o fever & Status Epilepticus  (? doi: http://dx.doi.org/10.1148/radiographics.22.4.g02jl15911. The full extent of the mass can be difficult to define on a pre-operative MRI scan and thus make surgical planning more challenging. There is continuing uncertainty about the role of pre-operative staging chest CT in the diagnosis of small pulmonary metastases in Wilms tumour. The use of contrast-enhanced MRI and diffusion-weighted sequences have further served to augment the information available to the clinical team during initial assessment of both neuroblastomas and Wilms tumours. • peak incidence is 2 to 3 years of age 3.
