A rare case of malignant schwannoma of the brachial plexus

Neurobroma is a common benign tumour occurring as part of an autosomal dominant disorder, neurobromatosis type 1, leading to the formation of benign tumours or neurobromas of the peripheral nervous system. Large neurobromas of the brachial plexus are rare and present a difcult challenge for surgeon due to the anatomical complexity of the brachial plexus. Dermal neurobromas usually present with swelling and occasional pain, but neurobromas associated with the brachial plexus present with pain and neurological symptoms. These plexiform neurobromas of the brachial plexus are known to undergo malignant transformation. Here, we present a case of a large plexiform neurobroma affecting the left brachial plexus and extending till the elbow, conrmed with MRI and surgical debulking was done.

Recklinghausen’S Disease

Abstract Two cases of solitary neurogenic tumors of the brachial plexus unassociated with von Recklinghausen's disease are presented. One patient had a malignant schwannoma. The lesion of the other patient was benign and was diagnosed pathologically as a plexiform neurofibroma. These uncommon neurogenic tumors of the brachial plexus unassociated with von Recklinghausen's disease pose diagnostic and surgical problems. The initial clinical presentation is usually that of a painless supraclavicular mass. At the time of surgical exploration, the exact site or nerve of origin cannot always be identified. If motor loss is caused by such a tumor of the brachial plexus, it usually indicates a malignant lesion and a poor prognosis. Although wide radical excision of a malignant neurogenic tumor is indicated surgically, one of our patients had an early malignant recurrence that necessitated immediate amputation.

Initial Injury

As the brachial plexus traverses the costoclavicular space, it is susceptible to compression by pathologies affecting the clavicle. Clavicle nonunions with hypertrophic callus may cause a delayed onset of brachial plexus palsy. We present a rare case of a floating shoulder injury causing medial and posterior cord brachial plexus palsy two months after initial injury. After the diagnosis was established, the patient was treated successfully with expeditious brachial plexus decompression, callus excision, and rigid osteosynthesis, with healing of the clavicle nonunion and scapular fracture, and recovery of sensory and motor deficits.
