Deep-seated intermuscular lipoma of posterior neck muscles: a case report and review of literature

Abstract

Abstract Lipomas are the most common soft tissue tumours, accounting for nearly 50% of all soft tissue neoplasms. Among the types of lipomas, intermuscular lipomas are rare. We report the case of a 46-year-old man with a deep-seated lipoma located between the trapezius and splenius capitis muscles in the posterior neck triangle. A successful surgical excision was performed. This case highlights challenges in diagnosis, surgical management, and the importance of complete excision in minimizing the risk of recurrence. This type of lipoma remains relatively understudied; therefore, further studies are needed to increase awareness of its incidence, clinical presentation, diagnostic evaluation, and optimal management.
