We reported a case of cervico-mediastinal tuberculous lymphadenitis followed by the development of pulmonary lesions and recurrent laryngeal nerve palsy. A 48-year-old man was admitted to our hospital due to fever, dry cough, and loss of body weight. He had no medical history of tuberculosis or other significant diseases. On admission, a right cervical tumor was palpable and chest X-ray films revealed widened superior mediastinum. Chest computed tomography showed multiple swollen mediastinal lymph nodes, including multiple low-density areas and contrast medium-enhanced septa and margins. Gallium-67 scintigraphy demonstrated abnormal uptake in the right cervix and mediastinum. A PPD skin test was strongly positive and ribosomal RNA of tubercle bacilli was detected in aspirated gastric juice. Although anti-tuberculous chemotherapy was initiated, fever and cough persisted, and hoarseness due to left recurrent laryngeal nerve palsy developed. One month later, chest X-ray films showed abnormal infiltration in the left upper lung field. The patient was sero-negative for HIV. To confirm the diagnosis, right supraclavicular lymph node biopsy was performed. Microscopic examination of the biopsy specimen revealed acid-fast bacilli and granuloma with central caseous necrosis surrounded by Langhans' giant cells and epithelioid cells. After 9 months of extended anti-tuberculous chemotherapy, the cervical and mediastinal masses receded and the abnormal chest X-ray shadows disappeared. Because the incidence of tuberculosis in Japan is gradually increasing among young people as well as the elderly, the differential diagnosis of this disease will become more necessary.
