Two cases of nontraumatic cerebrospinal fluid rhinorrhea were presumed to be an indirect manifesta tion of brain tumor. One patient had a parietal convexity meningioma and the other a cerebello pontine angle neurinoma. Following excision of the tumors these patients spontaneously developed cerebrospinal fluid rhinorrhea, which disappeared after the repair of fistulas at the base of the frontal ...

A case of extraaxial cerebello-pontine angle medulloblastoma in a 56 year old male is reported for its unusual location & age. Medulloblastoma accounts for 20% of brain tumors arising in childhood Peak incidence occurs between the 5 & 10 year of life.[1] Cerebellar medulloblastoma is classically seen during childhood, and less than 25% of these tumors are found in adults below 40 years of age. ...

Endolymphatic sac tumors (ELST) are rare papillary tumors of the temporal bone. Previously named as aggressive papillary middle ear tumors, they have recently been shown to arise from the endolymphatic sac. They are a rare in cerebello-pontine angle (CPA). We present a case of an ELST who presented as a CPA tumor with hydrocephalus. He underwent a ventriculo-peritoneal shunt initially. On explo...

Brugada syndrome (BrS) is one of the most common causes of sudden death in young people. It usually presents with life-threatening arrhythmias in subjects without remarkable medical history. The need for surgical treatment may unmask BrS in otherwise asymptomatic patients. The best anaesthesiological treatment in such cases is matter of debate. We report a case of neurosurgical treatment of cer...

Control of the timing of the inspiratory/expiratory (IE) phase transition is a hallmark of respiratory pattern formation. In principle, sensory feedback from pulmonary stretch receptors (Breuer-Hering reflex, BHR) is seen as the major controller for the IE phase transition, while pontine-based control of IE phase transition by both the pontine Kölliker-Fuse nucleus (KF) and parabrachial complex...

Central pontine myelinolysis is a rare but devastating cause of morbidity and mortality after orthotopic liver transplant. The exact cause of central pontine myelinolysis is uncertain. However, rapid correction of hyponatremia has been described as a major factor. We describe a patient with central pontine myelinolysis after orthotopic liver transplant in the absence of significant hyponatremia...

The development of mossy-fibre projecting precerebellar neurons (PCN) presents a classical example of tangential neuronal migration. PCN migrate tangentially along marginal streams beneath the pial surface from the lower rhombic lip to specific locations in the hindbrain, where they form precerebellar nuclei. Among them, the pontine neurons follow a stereotypic anteroventral-directed pathway to...
