1. There is no sex predilection and the ages in reported cases have ranged from 3 to 60 years, with a mean age of 22 years. Several systemic diseases, including Graves' disease,5 aplastic anaemia, and myasthenia gravis,7 have been reported in association with thymolipoma. As many as 40% of patients present with apparent cardiomegaly'; and barium swallow, angiocardiography,5 and pneumomedia*stinography8 have been used to distinguish the tumour from cardiac enlargement. Computed tomography may be of value in the detection and localisation of thymoma, which is usually detected as a mass of increased attenuation. The computed tomography appearances of mediastinal lipoma are characteristic, with a well-defined mass of low (from -40 to -60 Hounsfield units) attenuation value.9 In the present case computed tomography showed a mass of mixed density containing both fat and calcification. There was no evidence to suggest malignancy
