Clinical course and outcome of 34 patients with peripheral and visceral artery aneuryms, operated during 1975-1990, were analysed. There were 24 males and 10 females. Ages ranged from 14 to 87, with an average of 55 years. Peripheral aneurysms located most frequently in the lower extremity, and the incidence of various origin of the aneurysms were as follows: 14 in femoral, 5 in popliteal, 4 in internal iliac, 3 in subclavian, 2 in common iliac arteries, and 1 in each of vertebral, radial, splenic, renal and anterior tibial artery. Most common cause of aneurysm was arteriosclerosis. Multiple aneurysms were found in 59% of sclerotic type and in most of these with bilateral aneurysms in the iliac, femoral and popliteal. Ruptured aneurysms were seen in 26% of this series. Most of the aneurysms in the extremities were totally excised without difficulty, while the aneurysms in common iliac and internal iliac were opened with partial excision or obliterated with endoaneurysmorrhaphy. Arterial reconstruction was performed using saphenous vein graft or synthetic vascular graft, excepting that the internal iliac artery itself was not reconstructed. The early operative results were satisfactory, but late results showed two death and three complications of cardiovascular system. Therefore, careful follow up of the postoperative patients was recommended.

A 38-year-old man was admitted to our hospital with fever and skin rash, and he was diagnosed as having dermatomyositis. He was treated with anti-inflammatory steroid and immunosuppressive agents. On hospital day 48, chest computed tomography (CT) revealed a nodule measuring approximately 2 cm in size in the lower lobe of the right lung (S9). Bacterial and/or fungal infection was suspected, but there was no response to antibiotic or antifungal treatment. A week later, repeat chest CT revealed the tumor now measuring approximately 6 cm in size in the lower lobe of the right lung. We performed bronchoscopy, and bacteriological examination of the transbronchial biopsy specimen revealed pulmonary tuberculosis. Interferongamma release assay (IGRA) before the initiation of immunosuppressive treatment was negative, so we did not administer treatment for latent tuberculosis infection. He was, however, treated with isoniazid, rifampicin, ethambutol, and pyrazinamide for 9 months, following which radiological features improved gradually. Here we describe in detail this rare case of a negative IGRA result before immunosuppressive therapy in a relatively young Japanese man who went on to develop active tuberculosis with a rapidly-growing pulmonary lesion during hospitalization.
