Hypertrophy of inferior olivary nucleus may result from a varied spectrum of pathologies affecting the neuronal connections of the dentato-rubro-olivary pathway. This has been previously extensively described in adult patients as a result of various etiologies. We intend to elaborate on pediatric causes of hypertrophic olivary degeneration including infarction, neoplastic, demyelinating and infective pathologies as the underlying disorder with a few representative cases where available. A detailed explanation of underlying neuronal disruption responsible for this unique imaging finding will also be presented including diagrammatic illustration. Read More

A broad spectrum of intracranial cysts and cystic-appearing lesions exist with unique imaging and pathologic characteristics. Some cysts have a predilection for certain intracranial locations, which, in combination with specific imaging features, can help point towards a particular pathology and, in some cases, associated syndromes. Herein, we describe a pattern-based approach for evaluation of intracranial cysts and cystic lesions in order to narrow the differential diagnosis and assist in diagnosing an associated syndrome. Cyst pathologies to be discussed include: Arachnoid cysts, dermoid/epidermoid cysts, subependymal cysts, connatal cysts, cystic encephalomalacia, neuroglial cyst, perivascular spaces, choroid plexus cysts, and choroidal fissure cysts. Syndromes and conditions to be discussed include: Aicardi Syndrome (interhemispheric cysts), congenital muscular dystrophy (cerebellar cysts), congenital CMV (anterior temporal cysts), Zellweger syndrome (caudothalamic groove cysts), Glutaric Aciduria type 1 (middle cranial fossa cysts), and trisomy 18 (choroid plexus cysts). By being familiar with the pattern-based approach to characterization of the intracranial cystic lesions, radiologists can hone their differential diagnoses and differentiate benign/incidental lesions from ones that signify a broader pathology.
