Brain abscess is a focus suppurative infection of brain parenchyma. Each year, between 1500 and 2500 cases of brain abscess are diagnosed in the United States. The incidence rate of 1.3 per 100,000 person-years. They are more frequent in males. Most brain abscesses result from contiguous spread of infection from adjacent sites, trauma, or surgery. Hematogenous spread from distant sites of infection has been implicated in approximately 25% of brain abscess cases. Immunosuppressed individuals, AIDS, bone marrow and solid organ transplants, and neutropenia, are at greater risk for developing a brain abscess than immunocompetent individuals. Headache, nauseas and vomiting are the symptoms related to intracranial hypertension and focal neurological findings vary with the location and size of the abscess.
Aspiration of the pus is needed to confirm the diagnosis and to obtain tissue for culture. Patient outcome is usually favorable with early detection and aggressive treatment.
Hydatid disease is endemic in sheep and cattle-raising areas of the world. Signs and symptoms were related to the site and size of the cyst. Headache and vomiting due to increased intracranial pressure were the most common presenting symptoms. A round cystic lesion without perifocal edema and rim enhancement is the characteristic appearance on computed tomography scan. A magnetic resonance image visualizes the location of the cysts better than CT. The aim of the surgery is to remove the cyst without rupture. Chemotherapeutic agents such as albendazole and mebendazole due to the ruptured cysts during surgery or association with systemic hydatid disease are used. Cerebral hydatid cyst should be kept in mind for the differential diagnosis of cystic lesions.Keywords: Brain abscess, echinococcosis, brain, magnetic resonance imagingTurkiye Klinikleri J Surg Med Sci 2007, 3(11):71-76
