Intrathoracic hibernoma: an uncommon tumour

Hibernomas are uncommon benign tumours that arise from the remnants of fetal brown adipose tissue. They are usually asymptomatic and have a slow growth pattern. Intrathoracic and pleural locations are exceptional for localization of hibernoma. A review of the English language medical literature revealed more than 110 cases, 20 of which were intrathoracic. In the article below, we discuss a 40-year old male patient who had pleural involvement and was treated by surgical resection. Following resection, the patient has remained problem-free for nine years.
