Histopathological examination of the resected mass revealed a tuberculoma with central zone of caseous necrosis [Figure 4a] walled in by granulation tissue composed of epitheloid cells, lymphocytes and Langhan's giant cells [Figure 4b]. The overlying dura was adherent, and infiltrated by histiocytes and multinucleate Langhan's giant cells. [Figure 4].
