[Spontaneous intracranial epidural accumulation of air in a patient with excessive skull pneumatization].

We report a rare case of spontaneous epidural accumulation of air in the occipital region resulting from an unusual hyperpneumatization of the cranium in a 37-year-old miner. For suspected subarachnoid haemorrhage the patient was admitted to neurological department. Performed computed tomography (CT) revealed extensive hyperpneumatization of the cranium, involving also the upper part of the cervical vertebral column, and epidural pneumocephalus.

[Selected problems of neurofibromatosis with presentation of a case of multiple intracranial and intramedullary tumors].

A case of neurofibromatosis type II in a 19-year-old man is described with clinical and neuroimaging (MRI) findings. The diagnostic criteria of neurofibromatosis type I (NF1) and type II (NF2) and the optimal management options are still controversial. The authors suggest that this patient fulfills criteria of neurofibromatosis type II as well as partially neurofibromatosis type I.
