The goal of this study was to quantify the frequency of advanced spinal epidural lipomatosis (SEL) detected on lumbar magnetic resonance imaging (MRI) scans performed at the authors' hospital and to compare the frequency, cause, and progression of SEL in these cases with that reported in the literature. The total number of MRI examinations of the lumbar spine performed at this hospital over 45 ...

Overgrowth of epidural fat, known as spinal epidural lipomatosis (SEL), can cause symptomatic compression of the spinal cord, conus medullaris, or cauda equina. Suggested predisposing factors such as obesity, steroid use, and diabetes mellitus have been based on a few reported cases, many of which were not surgically confirmed. There is a paucity of epidemiological data in surgically confirmed ...

Pelvic lipomatosis is a rare disease by excessive proliferation of the mature fat in the pelvic extraperitoneal space. Cystitis cystica, often occurring concurrently with pelvic lipomatosis, is a rare proliferative inflammatory disease of the bladder. The diagnosis of pelvic lipomatosis is established on radiographic examination, not on pathology. We report a case of pelvic lipomatosis associat...

Pancreatic lipomatosis is characterized by fatty infiltration or replacement of the pancreas, and has been associated with many conditions. We recently experienced two cases of pancreatic lipomatosis in patients with pancreatic pseudocyst and a case of lipomatosis in diabetes mellitus. In these patients, abrupt obstruction of the main pancreatic duct with smooth tapering is a typical endoscopic...
