[A report of an intrathoracic case of hibernoma].

A successfully operated female patient, presenting hibernoma with intrathoracic location, is described. As shown by comprehensive survey of the pertinent literature, it is a matter of an exclusively rare condition--there are barely seven case reports worldwide on this particular type of tumor with such localization. The unusual clinical picture is revealed through retrospective analysis of the symptoms observed. Pitfalls and errors in the preoperative interpretation with a special reference to the massive process location are discussed. The results of diagnostic examinations, operative treatment and accurate histologic verification are documented by appropriate x-ray, scanographic and electron microscopic findings.
