Sciatica due to Schwannoma at the Sciatic Notch

Abstract

Schwannomas are rarely seen on the sciatic nerve and can cause sciatica. In this case report we aimed to present an unusual location of schwannoma along sciatic nerve that causes sciatica. A 60-years-old-man was admitted to us with complaints of pain on his thigh and paresthesia on his foot. Radiography of the patient revealed a solitary lesion on the sciatic nerve. The lesion was excised and the symptoms resolved after surgery.

Case Report: Sciatic nerve schwannoma - a rare cause of sciatica

“…On the other hand, schwannomas are placed in such a way that nerve fascicles are being pushed to the periphery, allowing their safe preservation following excision of the schwannoma 2, 4– 6 . Intra-operative nerve monitoring helps immensely to outline the course of the nerve and define the boundary of the tumor during its removal.…”

Plexiform schwannomas of the sciatic nerve:a case report and review of the literature

“…We searched the pubmed database using the keyword [(schwannoma*) AND (Sciatic)] from January 1, 2001 to December 1, 2022. Finally, 31 case reports were selected, with a total of 33 patients diagnosed with sciatic schwannoma [ [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] ] ( Table 1 ).
