[Intrathoracic lipoma].

A case of intrathoracic lipoma is presented. The radiographic signs of fatty tumours of the thorax are nonspecific. CT is helpful in the diagnosis and follow-up of this rare benign tumour. CT shows the exact location of the tumour and its characteristics. An attenuation coefficient of -140 to -70 HU is characteristic for the tumour and, if the tumor is asymptomatic, conservative management with careful follow-up is justified.
