Brachial Plexus Schwannoma – Case Report and Literature Review
Acta Clinica Croatica
-Schwannoma as an extracranial nerve sheath tumor rarely aff ects brachial plexus. Due to the fact that brachial plexus schwannomas are a rare entity and due to the brachial plexus anatomic complexity, schwannomas in this region present a challenge for surgeons. We present a case of a 49-year-old female patient with a slow growing painless mass in the right supraclavicular region that was diagnosed as schwannoma and operated at our department. Th e case is described to remind that in case of supraclavicular tumors, diff erential diagnosis should take brachial plexus tumors, i.e. schwannomas, in consideration. Extra caution is also required on fi ne needle aspiration procedures or biopsies of schwannomas due to the possible iatrogenic injury of the nerve and adjacent structures. On operative treatment of schwannoma, complete tumor resection should be achieved while preserving the nerve.
Schwannoma of the Brachial Plexus: A Rare Case Report
Iranian Journal of Otorhinolaryngology, 2020
Introduction: Brachial plexus schwannomas are extremely rare tumours of the head and neck region accounting for less than 5 % overall. Due to its rarity and anatomic complexity of the brachial plexus, schwannomas in this region present a diagnostic and surgical challenge to the surgeon. Case Report: We present a case of a 56-year-old female who presented with a slow growing right sided neck swelling associated with pain and tingling in the distal end of the right forearm. According to FNAC, imaging studies results, a diagnosis of benign neurogenic tumour possibly schwannoma was made. After taking proper consent patient underwent surgical excision of the tumour. Postoperatively, patient developed numbness and tingling in right arm and stiffness at elbow joint, which is showing improvement after regular physiotherapy sessions. Conclusion: Although brachial plexus schwannomas are extremely rare head and neck tumours they should be kept as a differential diagnosis in patients presenting...

Management of Intrathoracic Benign Schwannomas of the Brachial Plexus
Case Reports in Surgery, 2014
Primary tumours of the brachial plexus are rare entities. They usually present as extrathoracic masses located in the supraclavicular region. This report describes two cases of benign schwannomas arising from the brachial plexus with an intrathoracic growth. In the first case the tumour was completely intrathoracic and it was hardly removed through a standard posterolateral thoracotomy. In the second case the tumour presented as a cervicomediastinal lesion and it was resected through a one-stage combined supraclavicular incision followed by left video-assisted thoracoscopic surgery. A brachial plexus tumour should be suspected not only in patients with a supraclavicular or cervicomediastinal mass but also in those with intrathoracic apical lesions. A preoperative magnetic resonance imaging study of brachial plexus should be performed in such cases in order to plan the correct surgical approach.

Schwannomas of the head and neck as well as brachial plexus primary tumors are both uncommon entities, and combination of these conditions is quite rare. Schwannomas of the brachial plexus are usually asymptomatic and they present as slowly enlarging masses in the supra-or infraclavicular regions. Although imaging plays a routine role in the detection of these neoplasms, identification of the nerve origin is not often feasible until the time of surgery. Definitive diagnosis is based on histopathological features with presence of spindle-shaped Schwann cells. We report a case of a middle aged woman with left lateral mid-neck mass, which based on the clinical findings, was provisionally diagnosed as a painless lymphadenopathy. Ensuing excisional biopsy revealed the brachial plexus as the origin of a tumor, which subsequently was confirmed to be a schwannoma with microscopic evaluation. The course of disease was complicated with upper brachial plexus injury which was recovered by sural nerve graft.

Primary brachial plexus tumors are rare, usually benign, and in general have a good prognosis after surgical excision. We present a case of a schwannoma in which sonography enabled the correct diagnosis of a probably benign brachial plexus tumor. Key to the diagnosis was the demonstration of a smoothbordered, longish, and well-defined nodule along a brachial plexus nerve root. Cross-sectional imaging modalities that provide a high degree of soft tissue contrast and spatial resolution, such as sonography and MR imaging, were suitable methods to establish the correct preoperative diagnosis. Findings at CT, sonography, MR imaging, and surgery are discussed.

Lipomas are benign soft tissue tumours, progressively expanding in volume. Beside frequent aesthetic consequences, lipomas can also exert pressure on surrounding tissues and structures. A case of a subpectoral infraclavicular lipoma compressing the axillo-subclavicular neurovascular bundle, produced unilateral brachialgia, thereby simulating a Thoracic Outlet Syndrome. The expansive, but non-infiltrative, nature of the lipoma allowed local excision in the vicinity of the brachial plexus and infraclavicular vascular structures. Surgical removal of the lipoma resulted in complete remission of symptoms in the left arm and hand. In the presence of unilateral brachialgia, a subpectoral tumour causing a Thoracic Outlet Syndrome should always be excluded in the absence of other relevant pathology.
