Neurothekeoma of the median nerve: case report

We report the case of a large intraneural neurothekeoma of the median nerve at the wrist. Neurothekeomas are rare; they are small, superficial, and typically asymptomatic benign tumors of undetermined cellular origin. Complete excision is usually curative. This case is interesting owing to the tumor's large size and location within the median nerve, which made it highly symptomatic, mimicking carpal tunnel syndrome.     

Fibrolipoma of the median nerve: a case report and review of the literature

A 38 year-old patient presented with right median nerve distribution paresthesias. Electrodiagnostic studies confirmed severe carpal tunnel syndrome. A palmar mass prompted a magnetic resonance imaging scan, which suggested a fibrolipoma of the median nerve. Carpal tunnel release resulted in resolution of preoperative pain and paresthesias. We review the literature dealing with this primary nerve tumor.     

Fibrolipoma of the median nerve. A case report

The authors report a case of fibrolipoma of the median nerve in a 6-year old boy presenting as macrodactyly with clinodactyly. The causal relationship between the nerve lesion and the deformities is discussed. The difficulties of diagnosis of the condition are presented as are the difficulties of management where a balance has to be struck between conservative treatment and amputation.     

Ulnar subluxation of the median nerve following carpal tunnel release: a case report

Complications of carpal tunnel release, while infrequent, include incomplete release resulting in persistent symptoms or recurrence due to postoperative scarring, as well as iatrogenic damage to nerves and vessels. We present the case of a patient who underwent carpal tunnel release with resolution of symptoms in the immediate postoperative period. At one and a half years post release he started to experience numbness and tingling in a median nerve distribution triggered by repetitive ulnar to radial deviation of the wrist, with no symptoms at rest. Dynamic ultrasound showed a subluxation of the median nerve from one side of the palmaris longus tendon to the other. The patient's symptoms were triggered as the median nerve squeezed in between the palmaris longus and flexor digitorum superficialis tendons.     

Malignant peripheral nerve sheath tumour of median nerve - an unusual presentation: a case report

Malignant peripheral nerve sheath tumours (MPNST) are rare tumours, which usually occur in patients with multiple neurofibromatosis. They are common in the head and neck and trunk and only a few cases have been reported in the hand. Many of these occur in patients with von Recklinghausens disease and rarely as a malignant transformation of benign schwannomas. When they appear in the hand they often present with various symptoms. We encountered a patient who presented with a longstanding asymptomatic swelling of the palm. On excision the histopathology showed a high-grade malignant peripheral nerve sheath tumour, which led us to speculate that a malignant transformation had occurred in a pre-existing benign swelling. This is reported for its unusual presentation, which, to our knowledge, has never been described previously.     

Ancient schwannoma involving the median nerve: a case report and review of the literature

Ancient schwannomas are benign long standing schwannomas of the neural sheaths. Histological findings are these seen as in conventional schwannomas, but ancient schwannomas additionally demonstrate cystic hemorrhagic changes and degenerative nuclei with pleomorphism and hyperchromasia. Due to the nuclear atypia, and cystic degeneration, ancient schwannomas might be confused with malignant tumors on histology and imaging, leading to a radical surgical approach. The median nerve is rarely affected. We present a rare case of an ancient schwannoma involving the median nerve at the mid humerus. The tumor slowly grew up within ten years and become symptomatic with local pain, mild numbness in the distribution of the median nerve in the palm and Tinel’s test. The tumor was successfully removed by separating it from the nerve fascicles to negative margins. Post-operatively local symptoms relieved but minor sensory loss in the median nerve distribution in the palm was noticed which improved in the following six months. Ancient schwannomas can be misdiagnosed as sarcomas due to specific imaging and histologic findings. Patients’ physical examination, history and fine radiologic and pathology features should be cautiously interpreted in order to achieve correct diagnosis and avoid unnecessary wide tumor excisions.     

Schwannoma associated with anomalous division of the median nerve: case report

The authors present a case of a schwannoma associated with high division of the median nerve in a patient who had previously had a diagnosis of a ganglion. The case is presented and the literature concerning these 2 conditions is reviewed.
