Cavernous hemangiomas are among the least common benign chest wall masses. The aim of this study is to present a case of a 40-year-old women, with a giant cavernous haemangioma arising in the left axillary area. A 40-year-old female, was referred to a pulmonologist, after her chest radiograph showed, in the upper field of the left lung, a peripherally located shading (13 cm long and 3.5 cm deep) connecting with the pleura. The skin above the change was not discoloured. Contrast-enhanced CT showed a cavernous haemangioma (17 cm long and 13 cm wide) located mostly in the left axillary area. The main vascular supply of the haemangioma came from a direct branch of the left axillary artery, the left intervertebral arteries (levels Ill-VII) and a branch of the left internal thoracic artery. This report illustrates a rare case of a giant cavernous haemangioma and the treatment challenges it poses.
