title: Intraneural Lipoma of the Tibial Nerve: A Case Report.
abstract: Intraneural lipomas, neurofibrolipomas, lipofibromatous hamartomas, and perineural lipomas are subsets of hamartomas that typically present as fibroadipose, soft tissue masses within the epineurium of a nerve. Several cases involving intraneural lipomas of the median nerve in the upper extremity have been reported; however, owing to the lesion's rare incidence in the foot and ankle, only a select few cases involving the superficial peroneal nerve have been reported. We present the first case of a tibial nerve intraneural lipoma in a 42-year-old female with a follow-up period of 2 years. We discuss the clinical presentation, distinguishing features, surgical procedures, and short-term outcome regarding this unique tumor.
