A Case of Skull Bone Tuberculosis: Case Report

ABSTRACT

Tuberculosis originating in the skull bone is rare. We report a case of skull bone tuberculosis. A 72 year-old female was referred to us because of headache, swelling and tenderness in the left parietal area. She has been treated interstitial pulmonary fibrosis and pleural effusion at the department of internal medicine. Plain skull X-ray and CT scan revealed a 1.5x1.5 cm sized osteolytic lesion in the left parietal bone. Bone scan demonstrated a lesion of hot uptake in the left parietal region. After a left parietal craniotomy was performed, the involved bone flap and granulation tissue that attached to the dura mater were removed. Pathologic findings showed granulomatous inflammation with central caseous necrosis and peripheral collar of epithelioid cell interspersed with lymphocytes. A brief review of the literature was given.
