Benign Giant Retroperitoneal Neurilemmoma

Schwannoma is a benign tumour of peripheral nerve sheath. It usually arises from head, neck, and trunk. Retroperitoneal schwannoma is a rare entity, accounting for only 0.3–3% of total schwannomas. Majority of retroperitoneal schwannomas reported in literature have a diameter of 5 to 15 cm. Preoperative diagnosis is difficult due to low frequency, nonspecific clinical course, and nonspecific imaging features. Histology usually provides definitive diagnosis. Schwannomas are solitary, well-circumscribed, and noninvasive, so complete surgical excision provides good result. We report a case of a 23-year-old male, who presented with progressive abdominal distension and intermittent episodes of intestinal obstruction. CECT was suggestive of huge solid-cystic mass in abdominopelvic region. Image guided percutaneous aspiration revealed around 1 litre of frank pus and FNAC was suggestive of abscess. Exploratory laparotomy revealed a large 32 × 28 × 26 cm mass with solid and cystic components containing 1 litre of pus. Histological features of tumour were suggestive of benign schwannoma and immunohistochemistry for S-100 was positive. Postoperative recovery was uneventful. We report this case of a retroperitoneal schwannoma because of giant size, rare location, unusual presentation, and diagnostic dilemma.

“…8 Over the years there have been a number of case reports of large or giant retroperitoneal schwannomas. 2,[9][10][11][12] In most of these reports the diagnosis of retroperitoneal schwannomas was delayed primarily because it is rare to have schwannomas in the retroperitoneal region.…”

“…Benign schwannomas are generally slow growing and painless tumors originating from the Schwann cells of the peripheral nerve sheaths and predominantly occurs in females in between second and fifth decade of life 1 . 0.3-3.2% of benign schwannomas is found in retroperitoneal locations 2 . As these tumors are usually painless, symptoms occur due to expansion; hence diagnosis and treatment are usually delayed as was seen in the present case.…”

Schwannomas are usually benign tumors that result from the proliferation of the perineural cells. Since these tumors are very rare, misdiagnosis is common. Clinically, these tumors may present as a cranial neuropathy, abdominal or soft tissue mass, intracranial lesion, or with spinal cord compression. Histologically, these tumors are encapsulated, highly vascular, and composed of a homogenous pattern of biphasic fusiform-shaped cells that may have a palisaded appearance. We present a case of nineteen years old primigravida with 22 weeks pregnancy with an adnexal mass. The diagnosis of schwannomas was made on laprotomy and confirmed on histopathological examination. The case is reported not only due to its rarity but due to its association with pregnancy and its successful outcome.
