Nocardial brain abscesses are a rare central nervous system infection with high morbidity and mortality. Infection is acquired through inhalation or direct inoculation which then spreads hematogenously to other organs. They are usually associated with immunocompromised patients but may appear in otherwise healthy individuals. They should be considered in the differential diagnosis of brain absc...

sinus is a rare entity, with fewer than 20 cases reported in the literature1. We describe the unique computed tomogram (CT) and magnetic resonance (MR) imaging findings of an infant presenting with cerebellar abscesses and secondary obstructive hydrocephalus resulting from an occipital dermoid cyst with a complete dermal sinus, confirmed at operation. Early neurosurgical intervention is advocat...

We describe a previously healthy patient with chronic otitis media complicated with cerebellar abscess caused by Tsukamurella tyrosinosolvens. The organism was identified based on conventional biochemical identification methods, PCR-restriction fragment length polymorphism analysis of the hsp65 gene, and 16S rRNA gene sequencing. The patient was treated successfully with debridements and prolon...

Masked mastoiditis is a distinct form of mastoiditis with little or no symptomatology, characterized by its potential to generate severe otogenic complications. Therefore, suspected masked mastoiditis should be diagnosed and treated without delay. This study reports a rare case of masked mastoiditis, manifested by multiple intracranial complications in an immunocompetent girl. The child exhibit...

Results: Main complaints were: severe headache, vomitting, somnolens, imbalance and deafness.
