Pelvic lipomatosis: a case report and literature review

Abstract

Pelvic lipomatosis is a rare disorder where fat tissue deposition is observed in spaces of the pelvic area, causing extrinsic compression of the bladder, rectum and blood vessels. In the present report, the authors describe the case of a 48-year-old male patient presenting low back pain, dysuria and pollakiuria. Findings at excretory urography, computed tomography and magnetic resonance imaging are described. Keywords: Pelvic lipomatosis; Urography; Computed tomography; Magnetic resonance imaging.A lipomatose pélvica é uma doença rara, na qual se observa acúmulo de tecido adiposo na pelve causando compressão extrínseca da bexiga, reto e vasos sanguíneos. Neste estudo relatamos o caso de um paciente do sexo masculino, 48 anos de idade, que apresentou dores lombares e síndrome disúria-polaciúria. São descritos os achados na urografia excretora, tomografia computadorizada e ressonância magnética. Unitermos: Lipomatose pélvica; Urografia; Tomografia computadorizada; Ressonância magnética. AbstractResumo

Value of Multimode Sonography for Assessment of Pelvic Lipomatosis Compared With Computed Tomography

“…In patients with pelvic lipomatosis, there is abundant fatty tissue in the perirectal region. During transrectal sonographic examinations performed on our patients with pelvic lipomatosis, we found that there was thick and prominent hyperechoic fatty tissue between the rectum and prostate, which was consistent with the features of pelvic lipomatosis mentioned in the literature 5 , 11 …”

Pelvic lipomatosis associated with portal vein thrombosis and hydronephrosis: a case report

“…Additionally, compression of the venous system leads to lower limb edema and thrombophlebitis. 1 Because areas of symmetric fat density in the pelvic region on CT scans are suggested as diagnostic, surgery or a histopathological examination is often not required. Making a specific diagnosis of pelvic lipomatosis without an invasive procedure is useful.…”

“…Although pelvic lipomatosis is found most commonly in the third or fourth decade of life, it is rarely reported in children. 1 Obesity, endocrine dysfunction, such as diabetes mellitus and Cushing’s disease, lower abdominal or pelvic trauma, prior abdominal surgery, allergic conditions, and venous stasis, have been proposed for the cause of pelvic lipomatosis. However, the exact etiology of this disease remains unclear.…”

“…Clinical manifestations of pelvic lipomatosis vary depending on the compressed structures of the urinary system, intestinal tract, and venous system. 1…”
