Tubercular temporalis abscess with skull and dural invasion

Background: Mycobacterium tuberculosis infection rarely penetrates both skull and dura with temporalis muscle abscess formation. Methods: Case report and review of the literature. Results: A non-immunocompromised female patient with a right temporal mass underwent surgical resection. The tubercular abscess extended from the temporalis muscle to the skull and through the dura and subdural space with dissemination of the granuloma over the arachnoid membrane. Conclusion: Adequate debridement with a full course of antituberculous medication is necessary for complete treatment of these lesions.
