Myelography was performed on 78 patients with breast cancer who had signs or symptoms compatible with spinal cord compression. Of 42 patients (54%) with extradural defects, 21 (50%) had a complete block. All patients with positive myelograms (M+) had a positive bone scan and 41 of 42 (97%) had positive skeletal x-rays. Except for paraplegia, paraparesis, or a sensory level abnormality, signs and symptoms were usually not precise enough to accurately predict patients with cord lesions; however, back pain, paresthesias, and bladder or bowel dysfunction were significantly more common in M+ patients. Cerebrospinal fluid (CSF) protein was elevated in almost all M+ patients but also in approximately half of the M- group. Cytology and glucose analysis of CSF were not of value in predicting cord involvement. Response to treatment was better for patients with fewer sites of metastatic disease and a shorter time from diagnosis to treatment. There was no notable difference in survival between M+ and M- patients. Myelography remains the most precise tool for diagnosing spinal cord lesions. Unfortunately, the prognosis of patients with metastatic breast cancer is poor regardless of whether spinal cord compression is present.

A 72-year-old woman with a history of early breast cancer suffered a fracture of the eighth thoracic vertebra resulting in paraplegia. Magnetic resonance imaging (MRI) showed spinal cord compression by a tumor between the ninth and tenth thoracic vertebrae. Local radiotherapy was begun under the diagnosis of metastatic breast cancer, but bone marrow aspiration and biopsy subsequently revealed plasma-cell proliferation rather than adenocarcinoma. This case report serves to demonstrate that clinicians should consider multiple myeloma as a cause of lytic bone lesions without extraskeletal metastases even in patients with a history of breast cancer.
