We report four cases of tuberuculosis with the lymph nodes swelling in the porta hepatis. Case 1 is 52 years-old man, who was admitted to our hospital because of anorexia. The chest X-ray film showed abnormal shadow and he was diagnosed as tuberculosis by sputum examination. At the time of hospitalization, patient's conjunctiva is icteric on physical examination. The serum T-Bil was 3.21 mg/dL and D-Bil was 2.54 mg/dL. The enhanced CT showed compression of the extrahepatic common bile duct which was caused by enlarged lymph nodes secondary to tuberculous adenitis. Case 2 is 25 years-old man, who was admitted to our hospital because of low grade fever and lower abdominal pain. The chest X-ray film showed abnormal shadow and he was diagnosed as tuberculosis by sputum examination. An enhanced CT showed the swelling of the lymph nodes in the porta hepatis. Case 3 is 21 years-old woman, who visited the outpatient clinic bacause of neck lymph node swelling. And she was diagnosed as tuberculous adenitis of the cervical lymph-nodes by the neck lymph node biopsy. The patient complained of upper abdominal pain during the clinical course. The enhanced CT showed the swelling of the lymph nodes in the porta hepatis. A Case 4 is 31 years-old man, who visited to outpatient clinic bacause of fever. The chest X-ray film showed mediastinal lymphadenopathy, and he was diagnosed as tuberculosis by the thoracoscopic biopsy. The enhanced abdominal CT showed lymph nodes swelling in the porta hepatis. All of lymph nodes swelling found in our four cases markedly reduced in size on abdominal enhanced CT or ultrasonography after the initiation of anti-tuberculous standard chemotherapy. Symptom of all cases got better as well. In these clinical circumstances, it was clinically important to rule out malignant lymphoma and lymphadenopathy caused by cancer. The enhanced abdominal CT were useful for diagnosis and follow-up as tuberculous adenitis.
