Cliniclal Analysis of Microsurgical Reoperation after Lumbar Disc Surgery

Repeated surgery of the lumbar spine after lumbar discectomy was not uncommon. Total 817 cases of lumbar disorders were carried out surgical intervention in author's clinic from Jan. 1993. to May 1997. Among them, 82 cases were reoperated cases after lumbar disc surgery. The causes, methods and outcome of reoperation were reviewed. The most common causes of reoperation was epidural adhesion, and the most frequent method of reoperation was the interbody fusion with adhesiotomy. Epidural fibrosis was the major problem and must be studied forward for preventing reoperaion.

A Case of Calvarial Tuberculosis

Tuberculosis is still remains an important cause of morbidity and mortality throughout the world. Calvarial tuberculosis is a rare entity and when the primary lesion is in the calvarium without any detectable pulmonary lesion, it is even exeedingly rare. The authors present a case of a 60-year-old female patient presenting with headache and an area of painful protrusion in the left parietal scalp. Plain skull radiographs, computerized tomography(CT) scan and magnetic resonance(MR) image of the brain revealed an osteolytic lesion in the left parietal bone with an outward growth of the outer table. Chest radiograph was normal. At operation, the osteolytic lesion of the skull and the abnormal soft tissue were removed completely. Histopathological report on the surgical specimen confirmed the tuberculosis of the calvarium.
