Lipom der Thoraxwand

Lipom der

Thoraxwand mit interkostaler Ausdehnung nach intrathorakal und deutlicher Vorwölbung der Pleura

A rare case

of chest wall lipoma growing into the pleural cavity: a case report. MR image revealing an encapsulated fatty mass. The mass was located between the right serratus anterior muscle and the right rib cage. The size of the mass was estimated to be 5.5 × 2.3 × 5.2 cm. The mass was insulated in the right 6th–7th intercostal space resulting in herniation into the pleural cavity

Chest wall lipomas are benign fat containing thoracic lesion.

Epidemiology

While they can occur at any age, they typically occur in older patients who are 50-70 years of age, and they are most frequent in those with increased an increased body mass index.

Pathology

They are well-circumscribed encapsulated masses composed of adipocytes that differ very little from normal fatty tissue. Most lipomas that originate in the chest wall are deep lipomas, which tend to be larger and less well circumscribed than superficial lesions

Radiographic features

CT

Follows homogenous fat attenuation in general. However, multiple thin septa often are present that appear slightly enhanced on CT scans.

MRI

Lipomas generally appear to be internally homogeneous and do not enhance after intravenous contrast material administration. They typically follows fat signal on all sequences.

T1: can have high signal
T1 fat sat: shows fat suppression and has low signal intensity
