Navigating the Diagnostic Challenges of Cervical Plexus Schwannoma: A Rare Entity

Abstract

Schwannomas are the most commonly occurring neurogenic tumours. However, cervical plexus schwannomas are rare, and they mostly present with an asymptomatic neck mass. An elderly male with multiple comorbidities presented with a painless posterior triangle neck mass for a year without any neurological symptoms. After undergoing a few diagnostic modalities, including ultrasound-guided biopsy and MRI, the mass was suggestive of a schwannoma. Post-excision biopsy, no neurological deficits or recurrence were seen. This case exemplifies the challenges associated with diagnosing cervical plexus schwannomas and highlights the necessity of integrating multiple diagnostic modalities for their accurate identification. The rarity of this tumour, coupled with its uncommon anatomical location, highlights the importance of considering cervical plexus schwannomas in the differential diagnosis of asymptomatic lateral neck masses.
