[Thoracic bilateral myelolipoma]

Diagnostics, histogenetic derivatives and determination of the mediastinal neoplasms can still be problematic today despite the use of CT and MRT. Although the exact location and determination of neoplasmic density help to reduce the differential diagnostic spectrum in some cases, in the case of a 50-year old patient it was only via thoracoscopy and the taking of specimens that the diagnosis of a bilateral paravertebral crescent-shaped tumour of the posterior mediastinum as a rare myelolipoma could be obtained. Formal and causal pathogenesis of myelopomas are referred to in this paper with special reference to the clinical and pathologico-anatomical findings.
