ABSTRACT
We report the case of a 53- year-old man in whom the diagnosis of small cell lung cancer [SCLC] was made by the biopsy of a mass of the right trapezius muscle. A tumor was revealed on flexible bronchoscopy which pathological study showed tuberculosis [TB]. Chest computed tomography [CT] scan revealed findings related to the SCLC associated to micronodules and nodules compatible with pulmonary TB. Cerebral CT scan revealed a nodule of 4.5 mm in diameter presenting enhancement after contrast material injection thought to be a metastasis. The patient was administered antitubercular treatment. Fiveteen days later, the patient started chemoptherapy with etoposid and carboplatin. A control cerebral CT scan realized after the end of the chemotherapy [2 months and a half of antitubercular treatment] revealed numerous cortical and subcortical infracentimetric nodules with contrast enhancement with a tentorial and subtentorial location considered to be in relation with cerebral miliary TB. The nodule discovered on the first cerebral scan was therefore a posteriori considered to have been of tubercular origin. The PS of the patient rapidly worsened. He presented mental confusion and died in some days
