OBJECTIVE The aim of this study is to measure the height and volume of the bony part of the posterior cranial fossa (PCF) and the surface area of the foramen magnum (FM) using computed tomography (CT) scans and to correlate our clinical findings with the available current literature. MATERIALS AND METHODS This cross-sectional study was conducted in a tertiary care referral hospital in the Sou...

ase—A 30-year-old woman, gravida 1, presents at 32 weeks for sonography to assess fetal growth. She is otherwise healthy, and her pregnancy has been uncomplicated. Her 18-week anatomy scan results were normal. Her serum screen for aneuploidy was low risk. On this sonographic examination, the fetus is found to have normal growth and fluid. The anatomic survey results are normal aside from a cist...

BACKGROUND Cystic masses in the posterior fossa are ominous appearing lesions with broad differential diagnosis. Giant tumefactive perivascular spaces (GTPS) are rarely occurring pathological findings in the posterior fossa with unclear etiology and ill-defined long-term prognosis. CASE DESCRIPTION We present a case of a 15-year-old male diagnosed with posterior fossa GTPS. The patient remain...

BACKGROUND AND PURPOSE Qualitative radiologic MR imaging review affords limited differentiation among types of pediatric posterior fossa brain tumors and cannot detect histologic or molecular subtypes, which could help to stratify treatment. This study aimed to improve current posterior fossa discrimination of histologic tumor type by using support vector machine classifiers on quantitative MR ...

PURPOSE Our purpose was to determine the neuroradiologic findings of Marinesco-Sjögren syndrome on plain skull radiographs, CT, and MR images. METHODS Eight patients with proved Marinesco-Sjögren syndrome (age range, 4 to 56 years) had a total of nine CT scans, seven MR imaging studies, and two plain radiographic examinations of the skull. The findings were reviewed retrospectively, with part...

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....

usually located in the middle cranial fossa. Localizations in the posterior fossa are uncommon and generally remain asymptomatic or cause vague and non-specific symptoms. We describe the unusual case of a patient with an AC suffering from recurrent polymorphic vertigo with atypical nistagmus and transient sensorineural hearing loss. The clinical-diagnostic features are discussed, etiopathogenic...

Seven cases of aneurysm of the vertebral and basilar arteries, in which the clinical features suggested a diagnosis of posterior fossa tumour, are presented. Their clinical manifestations and the difficulties of diagnosis are discussed. These lesions may mimic cerebellopontine angle tumours or brain-stem gliomas, or, less commonly, the picture is one of a compressive lesion at the foramen magnu...
