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.

Long-term Follow-up Results of Anterior Cervical Interbody Fusion with and without Cervical Plate

Eighty-four patients whose cervical lesions not associated with any trauma or tumor were operated for anterior cervical interbody fusion. The patients were separated into two groups, one group operated with a cervical plate and the other group, without the cervical plate. The mean follow-up duration in anterior cervical interbody fusion with cervical plate cases was 16 months(from 6 months to 30 months), without cervical plate 35 months(from 6 months to 84 months). Retrospective analysis of the two groups were done in order to compare the incidence of postoperative complications, clinical outcome, and radiological changes. The most notable postoperative complications of the group operated without the cervical plate were migration of the bone graft(3.3%) and angulation(3.3%), whereas of the group operated with the cervical plate were screw loosening(4.2%) and infection of the operative wound(4.2%). Comparative analysis of the postoperative clinical outcome and changes in radiological measurement of the intervertebral heights and angles showed no statistically significant difference between the two groups. The results of this study suggest that whether or not the cervical plate should be used for anterior cervical interbody fusions requires a decision made carefully and meticulously by the operator, so that the possibility of any postoperative complications can be minimized.
