The authors present an unusual case of lumbar paravertebral fat-forming solitary fibrous tumor (SFT) that was surgically removed. A 53-year-old woman was admitted with a 3-month history of back pain and right paravertebral mass. Lumbar magnetic resonance imaging revealed a mass lesion located in the right paravertebral area at the level of L4 and deep into the paravertebral muscles. The patient was operated by lumbar paramedian incision, and total removal of the tumor was achieved, without intraoperative or postoperative complications. Histopathologic examination confirmed the diagnosis of fat-forming SFT. To our best knowledge, no similar case of lumbar paravertebral fat-forming SFT has been described in the literature. The radiologic, intraoperative, and histopathologic findings of this extremely rare case are discussed.
