Postcraniotomy gas-containing brain abscess: a neurosurgical emergency. Case report.
BACKGROUND
Gas-containing brain abscesses are very rare, and the majority are caused by Clostridium perfringens. We report a case of gas-containing brain abscess that required urgent surgery after a craniotomy for a brain tumor.


RESULTS
The patient was a 53-year-old male who presented with a cerebral neoplasm. A temporal lobectomy was performed and the diagnosis of low grade glioma was confirmed. Although the surgery was uneventful the postoperative course was complicated; the patient became agitated and febrile and deteriorated to a deep coma. A computed tomography scan demonstrated gas in the temporal fossa at the lobectomy site, producing mass effect. Urgent surgical debridement and drainage was performed and C. perfringens and mixed flora were found. Antibiotics were started and the patient's condition markedly improved. He was awake and alert, followed commands adequately and was extubated; however, after a week he suffered massive gastrointestinal bleeding and died.


CONCLUSIONS
Early recognition of a gas-containing brain abscess is of great interest to immediately start the appropriate treatment. Urgent surgical debridement and broad spectrum chemotherapy are major components in the management of this entity.
