Sagittal T1-weighted magnetic resonance imaging (MRI) of the brain with gadolinium contrast. A) Preoperative image demonstrates a 2.6 x 1.6 cm enhancing mass with surrounding edema. B) Axial diffusion-weighted MRI demonstrating perilesional edema but no solid areas of restricted diffusion to suggest abscess. C) Postoperative image one day after surgery demonstrating gross total resection. D) Postoperative image four months after surgery showing no recurrence.

A contrast-enhanced scan was performed, revealing an associated frontoparietal enhancing mass. magnetic resonance imaging (MRI) of the brain demonstrated a 2.6x1.6 cm mass with surrounding edema (Figure 1).
Intraoperative images of tumor. A) Superficial mass with well defined margins and surrounding normal brain tissue; B) resection cavity.

Opening the dura revealed a superficial mass with well defined margins that easily peeled away from the underlying parenchyma (Figure 2).
Pathological examination of tumor. A) Hematoxylin and eosin staining show necrotizing granulomas with peripheral palisading epithelioid histiocytes, giant cells. B) Acid fast bacillus.

Pathological examination demonstrated necrotizing granulomas with peripheral palisading epithelioid histiocytes, giant cells, and acid fast bacilli, consistent with cerebral tuberculoma (Figure 3).
