“…20 There is 5%-10% chance of recurrence, if not resected completely. 21,22 In the present case, we could achieve successful complete excision of the tumor inspite of the dangerous location. Though benign schwannoma has a good prognosis, malignant schwannoma is resistant to chemotherapy and radiotherapy, hence have poor prognosis.…”

Ovarian tumor is the most common diagnosis in postmenopausal women, presenting with a pelvic mass, though other surgical causes can still be a remote possibility. We report an extremely rare case of a woman, post hysterectomy, presenting with a pelvic mass where both clinical and radiological evaluations were suggestive of an ovarian tumor. The patient underwent laparotomy and a pre-sacral cystic mass was found and excised. Histopathology revealed a schwannoma as the final diagnosis. Hence, it mandates a high index of suspicion to consider other surgical possibilities, vigilant management in the form of advanced radiological evaluation, especially when dealing with doubtful cases of adnexal tumors prior to surgery.

“…Los shwannomas pueden aparecer en varios órganos o en los troncos nerviosos de todo el cuerpo, excepto los pares craneanos I y II, que están desprovistos de células de Schwann. Corresponden aproximadamente al 8% de los tumores del cerebro, observándose frecuentemente en el VIII par 13 . En los nervios espinales se desarrolla más frecuentemente a nivel lumbar.…”

“…En los nervios espinales se desarrolla más frecuentemente a nivel lumbar. Es el tumor benigno más frecuente de la médula espinal, constituyendo el 20 a 30% de los tumores de esta ubicación 5,13 . En el retroperitoneo los shwannomas son raros, constituyendo aproximadamente el 1% de los tumores retroperitoneales 14 .…”

“…Malignant retroperitoneal schwannomas are very rare and account for about 1% of all retroperitoneal schwannomas [10].The prognosis of benign schwannomas is good when excised. The most frequent complication is recurrence, probably due to incomplete excision, which is reported in 5-10% cases [11].…”

A young adult male 21-year-old presented to our out patient department (OPD) with history of periumbilical pain of 6 months duration with no other associated symptoms. Examination revealed a vague, hard, globular, retroperitoneal mass, of 5x4 cm, in the left para-umbilical region extending into lumbar region, with lateral and superior borders palpable only on deep palpation. Ultrasonography of the abdomen showed an encapsulated well-circumscribed solid mass, measuring 6x4 cm, in the left para-aortic area, with homogenous density and two tiny areas of necrosis, suggestive of paragangliomaora lymph nodal mass. CECT abdomen reported a large,well-defined, lobulated soft tissue mass lesion measuring approximately 6.2x4.8x7.3 cm in the left para-aortic aspect of retroperitoneum at the level aortic bifurcation with extension along the left common iliac artery. It showed mild heterogeneous enhancement within the mass on contrast study with mild peripheral vascularity. The mass was closely abutting the abdominal aorta with infero-medial displacement of the left common iliac artery and lateral displacement of the mid portion of the left ureter. CT guided FNAC of the mass revealed spindle cell tumour of nerve sheath origin probably of benign nature. MRI Lumbo-Sacral spine [Table/ Fig-1,2] reported a large T1 hypo intense and T2 heterogeneously hyper intense, well-encapsulated retroperitoneal mass at the level of L4 vertebra representing nerve sheath tumour.Following these investigative findings, an exploratory laparotomy was performed with midline approach. A mass was noted in the left paracolic gutter covered by the sigmoid mesocolon. Peritoneal reflection from the lateral paracolic gutter along with sigmoid mesocolon was reflected medially off the mass, preserving the inferior mesenteric vessels. The mass measuring 7x 8 cm, was found stretching and displacing the left ureter and gonadal vessels on its lateral aspect [Table/ Fig-3a] and was closely abutting the lower 5cm of the aorta and displacing the left common iliac vessels inferiorly [Table /Fig-3b]. The above structures were densely adherent to the capsule of this mass. These structures were meticulously dissected and preserved. One lumbar spinal nerve was found entering the mass postero-superiorly, which was divided. The entire mass was excised with the capsule intact and sent for histopathological examination.Gross examination revealed a well-circumscribed tumour with solid and cystic areas and calcific foci. Histopathologic examination aBstRaCt Neurilemmoma is a benign neurogenic tumour arising from Schwann cells of the peripheral nerve sheath, which is commonly seen in women in the 5 th decade. It rarely arises in the retroperitoneum, being more common in the head and neck region and extremities. Ancient variety of schwannoma is a long-standing tumour, is seen in the middle age and elderly age groups, and is associated with secondary degenerative changes. Herein, we report a case of benign retroperitoneal paravertebral ancient neurilemmoma occurring in a young m...
