Tuberculosis involving the central nervous system, a source of considerable morbidity and mortality, forms 5-10% of the disease burden associated with tuberculosis. Central nervous system tuberculosis may present as meningitis, tuberculoma, abscesses, cerebritis or miliary tuberculosis. The most common site of tuberculoma has been reported to be at the grey-white matter junction and the periventricular region. They may even be found in the epidural, subdural and subarachnoid spaces, and the brain stem, with the rarer sites of involvement being the cavernous sinus, sella turcica, hypophysis, hypothalamus, sphenoid sinus and the mastoid air cells. Although tuberculosis is very common in developing countries, with the increasing prevalence of immunosuppression owing to human immunodeficiency virus and patients surviving chemotherapy or organ transplantation, the incidence of tubercular infections has been rising in developed countries. The authors report a case of intracranial tuberculosis in a human immunodeficiency virus-negative patient, who underwent incomplete treatment for tubercular peritonitis and presented with unilateral ptosis. Tuberculous involvement was noted in a racemose pattern in the subarachnoid space, cavernous sinuses, suprasellar cistern and parasellar region. To the best of our knowledge, the term racemose pattern of tuberculoma has not been described before, while about 10 cases of tuberculoma involving the cavernous sinuses have been reported in the literature. Furthermore, the racemose pattern of tuberculosis in the subarachnoid space, as well as involvement of the cavernous sinus, hypothalamus, pituitary and the cisterns, developed paradoxically after initiation of antitubercular chemotherapy.
