Abstract A 77-year-old woman presented to hospital in December 2016 with back pain. She was diagnosed with thoracic compression fracture of the Th6 and Th8 vertebral bodies. She received conservative treatment, and the pain had improved. However, in September 2017, the pain worsened again, and in October 2017, paralysis of both lower limbs appeared, at which point, she was admitted to hospital again. Computed tomography (CT) revealed a tumor-like shadow around the Th6_Th8 vertebral bodies. Subsequently, she was transferred to our hospital. On admission, she was presented to the Department of Respiratory Medicine for abnormal shadows on chest CT. Chest CT revealed bronchiectasis and small nodules in the right middle and lower lobes and left lingular segment. As the sputum was not out, the patient’s gastric juice culture was analyzed; it was positive for

Myco-bacterium intracellulare. Needle biopsy samples from the areas of tumor-like shadows around the Th6_Th8 vertebral bodies were taken, and these were also positive for M.

intracellulare. Based on these fi ndings, we diagnosed the patient’s condition as vertebral osteomyelitis due to M.

intracellulare; subsequently, she received antimycobacterial therapy with rifampicin, ethambutol and clarithromycin, following which, she underwent radical debridement and

decompression surgery with anterior spinal fusion. Postop-eratively, we continued antimycobacterial therapy for 2 months, and no recurrence was detected. The rate of osteo-articular nontuberculous mycobacterial (NTM) infection has been reported to be 1_2%. Although vertebral osteomyelitis due to NTM is rare, clinicians should consider the combina-tion of nontuberculous mycobacteriosis and vertebral osteo-myelitis in cases such as the case presented herein.

Abstract A 61-year-old man had terrible cough. He lost consciousness and displayed hypoglycemic coma and shock. He regained consciousness after receiving glucose infusion. His sputum sample tested positive for tuberculosis (TB)-PCR. Based on these results, he was diagnosed with pulmo-nary TB. He was diagnosed with hemophagocytic lympho-histiocytosis (HLH) based on the symptoms of high fever, pancytopenia, hyperferritinemia, hypofi brinogenemia and hemophagocytosis in bone marrow, and with disseminated intravascular coagulation based on the symptoms of in-creased coagulation and fi brinolysis. He was successfully treated with antituberculous drugs, steroids and anticoagu-lants. This case emphasizes the importance of early

diagno-sis and treatment for the successful treatment of HLH asso-ciated pulmonary TB.
