We report a case of posterior fossa meningioma extending into the cervical jugular vein, which was successfully resected. A 57-year old male with ataxia and mild hypogeusia was admitted to our hospital. MRI demonstrated a well-circumscribed large posterior fossa mass with extracranial extension through the internal jugular vein. Two-staged surgical treatment was then performed. The mass in the posterior fossa was removed at the first operation. The tumor was invading into the sigmoid sinus which was filled with tumor. The second operation for extracranial mass was performed 1 month later. Transcervically, the internal jugular vein obstructed by tumor was successfully removed. The post-operative course was uneventful and histopathological examination revealed the fibrous meningioma in the posterior fossa, but the intravenous portion of the tumor showed more atypical findings. Such a case is quite uncommon and the mechanism of tumor extension with different histological features is discussed.

Congenital melanocytic nevus (CMN) syndrome is a rare, non-familial neural ectodermal dysplasia characterized by CMN combined with extracutaneous abnormalities, predominantly involving the central nervous system (CNS). The pathogenesis of CMN syndrome is thought to result from early post-zygotic somatic mutations. CNS melanosis frequently affects the anterior temporal lobes, brainstem, cerebellum, and cerebral cortex.

Background And Objectives: The middle fossa approaches are tremendously versatile for treating small vestibular schwannomas, selected petroclival meningiomas, midbasilar trunk aneurysms, and lesions of the petrous bone. Our aim was to localize the internal acoustic canal and safely drill the petrous apex with these approaches. This study demonstrates a new method to locate the internal acoustic canal during surgery in the middle fossa.

Background/objectives: Intracranial arachnoid cysts (ACs) may be congenital, primary, or secondary due to trauma. These cysts are benign, contain cerebrospinal fluid (CSF), and are classified based on location, size, and their clinical symptomatology. They are uncommon lesions in children, rarely leading to severe mass-effect neurological symptomatology.

Background: Posterior fossa syndrome (PFS), also known as cerebellar mutism syndrome, occurs in about 25% of pediatric patients undergoing resection of a posterior cranial fossa medulloblastoma. It is characterized primarily by mutism or reduced/impaired speech and may include variable symptoms such as motor dysfunction (apraxia, ataxia, hypotonia), supranuclear cranial nerve palsies, neurocognitive changes, and emotional lability. Long-term multidisciplinary rehabilitation is typically required, with recovery taking approximately six months, though many children experience long-term residual deficits.
