Schwannomas are encapsulated tumors arising from Schwann cells of the nerve sheath, and are usually solitary sporadic lesions. The schwannoma of the ilio-hypogastric nerve especially in the retro-petoneal space is very rare. We are reporting a case of the schwannoma of the left ilio-hypagastric nerve over the psoas muscle. The diagnosis was done by ultarsonogrsphy and MRI. The histopathological study confirmed the diagnosis. The tumour was excised through retro-peritoneal approach. By this approach total excision of the tumour with preservation of ilio-hypogastric nerve is possible. Journal of Science Foundation 2019;17(2):71-74

ABSTRACT Schwannoma is a benign tumor that originates from perineural Schwann cells of nerve sheath. They are solitary, wellencapsulated, slow-growing adjacent to the parental nerve but extrinsic to the nerve fascicles. Approximately 25 to 45% of all schwannomas are seen in the head and neck region and are found rarely in the oral cavity. Most of the intraoral schwannomas are located in the tongue. Palatal schwannoma is very rare as till date and only 16 cases have been reported; one such rare case we came across is reported here. How to cite this article Hameed PSS, Arora N, Malhotra V.

Nerve Sheath

Schwannomas are benign nerve sheath tumors composed of Schwann cells, which normally produce the insulating myelin sheath covering peripheral, cranial and autonomic nerves. Twenty-five to forty-five percent of all schwannomas occur in the head and neck region, but location of such tumors in the larynx is rarely observed. The present report is aimed at describing a clinical case of laryngeal schwannoma, with emphasis on sonographic findings.

A schwannoma is a slow-growing, neurogenic tumor composed of Schwann cells arising from a peripheral nerve sheath. The authors present a rare finding of a schwannoma of the sural nerve that was overlooked in a 51-year-old female with radiating foot pain. This case highlights the clinical implications and important teaching points in recognizing a schwannoma of the foot.

Rare Case Report

Introduction: Schwannoma is the most common benign tumor of the peripheral nerve sheath. They appear in the sheath of the nervous fascicle and are well-defined masses, which allow their dissection of the underlying neural bundle. Sciatic nerve involvement is rare, accounting for less than 1%. Case report: Male, 83. He has had sciatica on the left for 10 months. With progression of pain, VAS of 9 and difficulty to walk for 1 month after admission. On physical examination, a positive tinel sign in the left gluteal region with tactile perception of nodular lesion in sciatic nerve topography. Preserved and discrete hypoesthesia strength in left sciatic nerve territory. MRI shows nodular lesion, suggestive of neural sheath tumor. Undergoing a surgical procedure for excision of the lesion. Total resection of the lesion was performed with no changes in monitoring potential. The patient was discharged from the hospital the next day, with a VAS of 0, with no other complaints and pain control. Discussion: Schwannomas have a long subclinical course, their clinical presentation is usually misleading. The referred patient started with sciatica, with painful progression to VAS 9. The diagnoses of sciatic nerve schwannomas are made with MRI. The definitive diagnosis is possible after the histopathological study. The treatment of this tumor is by massive excision and preservation of the nerve. Conclusion: Studies regarding sciatic nerve Schwannoma are scarce. There is a need for further studies on the case, to train health professionals to recognize and effectively treat the pathology.

SummaryThis case report describes a melanin-containing neurofibroma involving a spinal nerve root. Electron microscopy of the tumor shows that neoplastic Schwann cells are capable of melanogene-sis. Although this capability is suggested in the literature, few reports provide ultra-structural confirmation.The likely identity between reported “cellular blue nevi of spinal nerve roots” and nerve sheath tumors is discussed. It is possible that pigmented nerve sheath tumors behave more aggressively than nonpigmented ones, although it is debatable.

Memory Disturbance

Introduction: Meningiomas are the third most common intracranial tumors in adults after glial tumors and metastases. Olfactory groove meningiomas often grow without symptoms due to their slow growth rates and location in the frontal lobe. Optic nerve sheath meningiomas are benign neoplasms of the meninges surrounding the optic nerve. The coexistence of olfactory groove and optic nerve sheath meningiomas without any history of neurofibromatosis or radiotherapy has never been reported in the literature. Case Report: A 36-year-old female patient presenting with anosmia, headache, memory disturbance, and visual impairment and operated with the diagnosis of olfactory groove meningioma was reported. In the postoperative period, optic nerve sheath meningioma was detected in the imaging performed due to the persistence of visual impairment. Conclusion: Olfactory groove and optic nerve sheath meningiomas are rare tumors and can be diagnosed late because they progress slowly. Early diagnosis and treatment may affect the prognosis and morbidity of these patients favorably.
