Body computed tomography in the diagnosis of malignant melanoma metastases

The results of body CT examination in 32 cases of histologically proven malignant melanoma are reviewed. In a total of 38 examinations, positive findings were obtained in 27 cases (71%). Metastases were detected in the lungs (6 cases), liver (2 cases), and lymph nodes (26 cases). Local recurrences were recognized in 2 cases. Clinical suspicion of metastases was supported in 19 cases (50%), suspected metastases were not confirmed in 5 cases (15%), and additional evidence of metastasis was obtained in 14 cases (37%). CT was of particular value in demonstrating additional metastases in the lungs and lymphadenopathy in the abdomen and pelvis.
