Dandy-Walker Malformation (DWM) is a rare congenital anomaly of the posterior cranial fossa. Features DWM include hypoplasia cerebellar vermis, enlargement fossa, and cystic dilatation fourth ventricle. MRI modality to confirm diagnosis. Treatment usually symptomatic required when signs hydrocephalus develop. Rare cases asymptomatic diagnosed incidentally are reported in literature. We report c...

The CT and MR appearance of a case of low-grade adenocarcinoma of probable endolymphatic sac origin is presented. The tumor destroyed a large part of the posterior temporal bone and showed prominent extension into the posterior cranial fossa.

abstract a patient with a 3-month history of headache refractory to pain medication was admitted. the ct scan and mri showed evidence of a posterior fossa mass. this was pathologically confirmed as an extra medullary plasmacytoma (emp). he had a pathologic fracture of the left humerus 7 years ago while the radiologist was unaware at the time of diagnosis. a solitary bone plasmacytoma (sbp) was ...

This paper presents three patients with a triad of syringomyelia, midline posterior fossa cysts, and hydrocephalus. In the first patient, the clinical presentation was related to spinal cord cavitation, and the cranial anomalies were unexpected. In cases 2 and 3, the brain anomalies dominated the clinical picture, and syringomyelia was unexpected. These cases show that an examination of the who...

AIM The anatomic characters and applicability of the extended pterional transtemporal transtentorial (EPTT) approach versus the subtemporal transtentorial (ST) approach for surgical treatment of petroclival tumors were evaluated. MATERIAL AND METHODS Ten sides from five adult Chinese injected cadavers were manipulated using both two approaches. Four deep bony anatomic landmarks were specified...

Acute neonatal posterior fossa subdural hematoma has been documented 13 times since 1940. Typically it occurs in a full-term infant whose delivery is complicated by forceps extraction or breech delivery. Lethargy, irritability, and respiratory irregularities occur within the first few days of life. Tense anterior fontanels and increasing head circumference result from progressive hydrocephalus....
