Introduction: Vascular anomalies, comprising up to 4.5% of the general population, are aberrations occurring during vascular development. Vascular abnormalities are frequently identified in children and frequently exhibit characteristics similar to nerve sheath tumors. We report a case of 16 years old boy with a arterio-venous (AV) malformation (AVM) affecting the brachial plexus. We discuss the clinical features, diagnosis, treatment, and histopathological findings in this patient and review the relevant literature.
Case report: A 16- year-s old boy presented with pain, paresthesia, swelling, and reduced grip strength of the hand. Radiological investigations revealed a vascular lesion encasing C5, C6 nerve roots and displacing the C7 root. Near total surgical excision of the lesion was done with preservation of nerve. Histopathology confirmed arteriovenous AVMmalformation with distinct features.
Conclusion: High-resolution ultrasound is crucial for diagnosing soft- tissue vascular anomalies. Surgeons well versed in micro surgical skill play a vital key role in minimizing neural deficits. In the case of vascular malformations of brachial plexus, near total excision is the most favorable option.
