Epidural hematoma of the posterior cranial fossa (EHPCF) is a rare complication in head injuries. Furthermore, nonspecific clinical signs and the rare occurrence of this lesion in craniocerebral injuries make the establishment of a diagnosis more difficult. The aim of the paper is to point to the advantages of early diagnosis. During the 1982-2008 period, 18 patients with EHPCF were operated on...

Posterior fossa emissary veins are valveless veins that pass through cranial apertures. They participate in extracranial venous drainage of the posterior fossa dural sinuses. The mastoid emissary vein, condylar veins, occipital emissary vein, and petrosquamosal sinus are the major posterior fossa emissary veins. We believe that posterior fossa emissary veins can be detected by radiologists befo...

Mutism and neurobehaviour symptoms are well known features, which may occur following surgical excision of mass lesion of various histopathologies in the posterior cranial fossa, during the postoperative period. Mutism may be rarely associated with ataxia of eyelid closure and paresis of external ocular muscles. However, internuclear ophthalmoparesis is not reported in association with mutism f...

Multiple cranial nerves palsies following a posterior fossa exploration confined to an extradural compartment is a rare clinical presentation. This case report describes a young man who developed a unilateral abducens and bilateral facial nerve palsies following a posterior fossa exploration confined to an extradural compartment. There are different theories to explain this presentation, but th...

Folds of the meningeal layer of the dura mater, the falx cerebri and tentorium cerebelli, traverse the vertebrate intracranial cavity and thus compartmentalise the brain. The falx cerebelli, another dural fold, is found in the posterior cranial fossa and attaches to the inferior aspect of the tentorium cerebelli and to the internal occipital crest. We present a case of a duplicated falx cerebel...

Arachnoid cysts account for almost 1% of neoformations located in the cerebellopontine angle. The aetiopathogenesis is unknown. Arachnoid cysts of the cranial posterior fossa may produce symptoms typical of a tumour such as headache, dizziness, tinnitus and progressive sensorineural hearing loss. Management of these lesions is still controversial; if the arachnoid cyst is symptomatic, surgical ...
