Malignant rhabdoid tumors are aggressive malignancies that can rarely present as hepatic masses in the pediatric population. The imaging findings are often nonspecific and usually suggest other more common hepatic tumors. We report the radiologic appearance of malignant rhabdoid tumor in a 3-month-old female with pathologic correlation.
Noninvasive imaging biomarkers readily assessed with PET/CT or MR imaging provide functional data that are absent from conventional anatomic imaging and that can be used to guide tailored treatment approaches in patients with squamous cell carcinomas of the head and neck.
Neuroendocrine tumours (NETs) of the head and neck are rare neoplasms and can be of epithelial or non-epithelial differentiation. Although the natural history of NETs is variable, it is crucial to establish an early diagnosis of these tumours as they can be potentially curable. Conventional anatomical imaging and functional imaging using radionuclide scintigraphy and positron emission tomography/computed tomography can be complementary for the diagnosis, staging and monitoring of treatment respo...
onographic evaluation of hip dysplasia has been used since the early 1980s and is now a well-established procedure for the assessment and monitoring of neonatal and infantile hip stability. This same technology can be applied to glenohumeral joint evaluation. Computed tomography (CT) was the first radiographic modality to be used to describe shoulder instability in children with Erb palsy 25 years ago, 1 followed by magnetic resonance imaging
