title: Epidural spinal cord compression as the presenting manifestation of tumor of unknown origin.
abstract: Epidural spinal cord compression is a common complication of malignancy. In the majority of cases, the primary site is known at diagnosis or is evident following limited investigation. During the period January 1975 to December 1987 we encountered seven cases of tumor of unknown origin presenting as cord compression. Myelography detected the site of cord involvement in six cases, and computed tomography of the spine was utilized in one case. All seven patients underwent laminectomy. Histologic diagnosis was adenocarcinoma in four cases, squamous in one case, and large cell undifferentiated carcinoma in two cases. Evaluation for a primary site was unrewarding. Prognosis was poor, with a median survival of 10 weeks. Only one patient had a satisfactory response to treatment.
