“…Fluorodeoxyglucose-positron emission tomography (FDG-PET) is reportedly useful for diagnosing hibernomas and may have led to a definitive diagnosis if preoperatively performed. 4,5 There are also reports of CT-guided needle biopsies providing a definitive diagnosis in a lumbar region tumor. 3 However, because of the risk of dissemination associated with a potential liposarcoma, in this case, a biopsy was deemed inappropriate.…”

“…Using the PubMed database, we searched for "hibernoma retroperitoneal" and found nine cases of this tumor in the abdominal cavity. [2][3][4][5][6][7][8][9][10] To our knowledge, this is the second case report of laparoscopic surgery for hibernoma removal. The patient's short-term results demonstrated that laparoscopic surgery is a viable option for hibernomas (Table 1).…”

Hibernomas are extremely rare, benign tumors of brown fat origin with no specific symptoms. Surgery is the only treatment option, and because a definitive preoperative diagnosis is often not obtained, open surgery is usually chosen. In this case, we performed laparoscopic surgery on a 33-year-old woman with retroperitoneal hibernoma. As in most cases, a definitive diagnosis had not been preoperatively made; therefore, we laparoscopically removed the retroperitoneal tumor of unknown pathology as a diagnostic treatment. We chose laparoscopic surgery because of the magnifying effect of the laparoscope and to minimize scarring. The surgery was uneventful, with a procedure time of 280 minutes and a blood loss of 20 mL. The postoperative course was uneventful with no complications or recurrence. We conclude that laparoscopic surgery may be a viable option for hibernomas.
