Schwannomas are rare benign tumors posing differential diagnosis problem with carpal tunnel syndrom if it presents complications such as numbness and tingling or neurofibromatosis especially when shwannomas are multiple. We present a case of woman presenting swelling of the palmar aspect of wrist with functional signs guiding the clinical diagnosis of carpal tunnel syndrom. On MRI the mass was well encapsulated to sharp limits without any peritumoral edema. The diagnosis was confirmed at histological exam after surgical intervention. However, It is essential to have a presumption diagnosis of schwannoma oriented by imaging such as ultrasound and especially MRI to have an idea on the dissection of the tumor, the schwannoma being easily resectable with easy dissection from the nerve fibers that surround it, while neurofibromatosis requires sacrifices of nerve fibers due to difficult dissection. Only surgical resection is considered a curative treatment. Generally, there are no sequelae of postoperative paresthesia, long-term recurrence or degeneration.
