Extrapulmonary tuberculosis (TB) is not a rare condition and can involve almost every organ. While nasal cavity and paranasal sinus involvements are quite rare, frontal sinus involvement has been reported in a few cases in literature. 58 years old female patient applied with complaints of dripping starting from the scar tissue developed after the trauma of frontal region. Inflammation secondary to osteomyelitis in left frontal bone was detected on cranial MR and paranasal CT and a debridement was performed. In the pathological evaluation of the debridement material, multi nuclear giant cells, granulomas consisted of epithelioid histiocytes and caseification necrosis were detected. A treatment was started with the diagnosis of extrapulmonary tuberculosis. Sinus tuberculosis can arise as secondary infections of adjacent tissues or lungs and rarely as a primary infection. While cases of maxillary and ethmoidal sinuses were frequently reported, frontal sinus involvement is rare. Medical treatment alone can be sufficient in limited and early diagnosed tuberculosis infections of the head, but it has been reported that more satisfactory treatment could be achieved with the combination of surgical and medical treatment.
