We present a 43-year-old male patient who developed a giant cholesteatoma with lateral sinus obliteration and involvement of the posterior cranial fossa. The only complaints were left-sided aural discharges and total sensorineural hearing loss. Examination revealed a mass lesion consistent with cholesteatoma within the left middle ear. Computed tomography and magnetic resonance imaging showed a...

This study presents two cases of SSDH after posterior fossa surgery. The first case was a 44-year-old man who harbored a fourth ventricle metastatic adenocarcinoma, and the second case was a 4-year-old boy with a ...

Paediatric brain tumours commonly arise in the posterior cranial fossa. Early diagnosis is often challenging due to initial non-specific clinical symptoms, especially in very young children. The typical MR features of tumours in this region including medulloblastoma, ependymoma, juvenile pilocytic subtype of cerebellar astrocytoma, brain stem glioma and atypical teratoid-rhabdoid tumour are ill...

The present study analyzed a case of immature teratoma in the posterior cranial fossa of an infant and compared the clinical data with the associated literature. Ventricular drainage was initially performed upon the patient's admission to the hospital. Following adequate pre-operative preparations, the tumor in the posterior cranial fossa was resected on the third day. No significant neurologic...

several lesions (inflammatory, neoplastic and congenital) can involve in the skull base. the role of imaging is to detect the location and extension of lesion, determine mass and mass like lesions, differentiate benign from malignant tumors, detect invasion to adjacent structures and make decision in surgical planning. skull base divides to anterior, middle and posterior cranial fossa and some ...
