Dumbbell shaped giant intramuscular pelvic lipoma: a rare cause of sciatic nerve compression

Background: Lipoma is a common benign mesenchymal tumor that is typically located in the subcutaneous tissue and rarely symptomatic. Sciatica can be a result of various etiologies but a giant intramuscular pelvic lipoma causing sciatic nerve compression is rare, with not more than 10 cases reported so far in the literature. Case Presentation: We report a case of a 36-year-old female who presented with a complaint of gradually worsening sciatica for 6 months. Magnetic resonance imaging showed a large well-defined intramuscular dumbbell-shaped mass in the right gluteal region, herniating through the sciatic foramen into the pelvis. After successful resection of the mass transabdominally, the histopathological examination confirmed the diagnosis of a benign lipoma. The patient improved gradually thereafter and is asymptomatic since then. Conclusion: Our case not only describes the appropriate diagnosis and surgical management of this common benign entity with a rare location and even rarer clinical presentation but also creates a paradigm for future insight into the effective management of such a patient.

Laparoscopically Assisted Transperineal Approach in the Management of a Giant Pelvic Lipoma.

Summary:Giant lipomas affecting the retroperitoneum and pelvis are quite rare. The surgical management of these lesions may be technically demanding and controversies exist with respect to diagnosis, competences being involved, type of surgical approach, radicality, and timing. A unique case presentation of a giant lipoma occupying the whole pelvis and the gluteal region is presented. Due to its size, many anatomical areas are involved, requiring the expertise of multiple specialists to treat. After multidisciplinary counseling, the lesion is radically resected in one stage by using a new videolaparoscopically assisted transperineal access to the pelvis. This type of surgical approach may be of interest for resecting pelvic tumors in women and men.

INTRODUCTION: Pelvic lipomatosis is a rare benign disorder characterized by deposition of mature fat tissue in the pelvic cavity and absence of delimitation by a capsule. Peak incidence of this disease is between 25 to 60 years of age with a staggering male predominance of 10:1. CASE REPORT: A 45 yr. old male presented with epigastric swelling and abdominal pain. Clinically, he was diagnosed with epigastric hernia. Ultrasound showed bladder wall thickening with bilateral hydroureteronephrosis. CT showed bilateral hydrouretronephrosis with pear shaped bladder, non-encapsulated fatty mass surrounding urinary bladder symmetrically, with attenuation similar to that of subcutaneous fat suggesting extensive pelvic lipomatosis. On laparotomy there is a large pelvic lipoma filling the whole of pelvis and bladder was surrounded by fatty tissue all around along with lipoma of the cord. Patient underwent pre peritoneal hernioplasty for ventral hernia and excision of pelvic lipoma and the lipoma of the cord. DISCUSSION: Pelvic lipomatosis is a benign overgrowth of adipose tissue with small amount of inflammatory and fibrotic components found especially in the perivesical and perirectal spaces. The best definitive diagnostic procedure is CT. Various treatments have been attempted, but no single treatment has proved effective to date.

Pelvic Lipoma in a Case of Stage-II Cervical Carcinoma - A Case Report

Retroperitoneal pelvic lipomas are so rare that there are only few cases reported in literature. Current imaging techniques such as USG, CT & MRI are helpful in diagnosis. A case of pelvic lipoma in a patient with stage-II cervical carcinoma is described. Initial ultrasound showed an irregular mass in the cervix with suggestion of an echogenic lesion in left side of pelvis. Plain and contrast enhanced CT showed a homogenous fat attenuation mass in the left side of pelvis with a faintly visible capsule which did not enhance post contrast. MRI permitted unequivocal diagnosis of lipoma. The usefulness of various imaging methods is discussed in correctly diagnosing the entity and avoiding unnecessary surgery in asymptomatic patient.

Management of Large Retroperitoneal Lipoma in a 12-Year-Old Patient

Retroperitoneal lipomas are rare tumors. The etiology of their proliferation is uncertain. Metabolic and genetic causes have been reported. We present the case of a 12-year-old patient with a large pelvic lipoma causing dysuria and pelvic pain. Magnetic resonance imaging revealed the existence of a large retroperitoneal fat tumor. Ultrasound-guided fine needle biopsy was performed to exclude malignancy. The biopsy specimen revealed tissue consistent with a benign lipoma tumor. Exploratory laparotomy revealed a solid lipoma of the retroperitoneal space 8 x 6 cm and weighing 300 g. The patient had a good postoperative performance status. Lipomas should be considered in the differential diagnosis of a solid tumor in the retroperitoneal space.

Surgical approach to a large dumbbell-shaped pelvic lipoma extending through the obturator foramen

Lipomas are the most commonly occurring mesenchymal tumors. We report a technique used to manage a patient with a large dumbbell-shaped pelvic lipoma passing through the obturator foramen. Using the combined expertise of an orthopedic and pelvic surgeon, successful and safe removal of this benign dumbbell-shaped pelvic lipoma was achieved.

Pelvic lipoma causing venous obstruction syndrome

Reports of extrinsic obstruction of a major venous channel in the lower limb caused by compression from mass lesions 1-3 are uncommon; ~6 Pochelle et al. in 1991 reported the third case of venous obstruction associated with pelvic lipomatosis. 4 We report a case of right external iliac vein compression, not by pelvic lipomatosis but by a large discrete pelvic lipoma, this being the first known report of its kind.
