Intraneural Lipoma of the Digital Nerve: A Case Report and Literature Review

Abstract

Intraneural lipomas are rare soft-tissue tumors that can occur particularly within the median nerve. Even fewer cases have been reported of their occurrence within the ulnar nerve. These masses can cause compression neuropathies. In this report, we present the first documented case of an intraneural lipoma of an ulnar digital nerve.

Intraneural lipoma of the median nerve: a case report

“…Postoperatively, the patient experienced some mild paraesthesia in the ring finger, which did resolve over time. No information about recurrence was provided [2].…”

“…It occurs in a younger age group with no sexual predominance. Due to these differences, these lesions are managed differently [1,2].…”

Rare case of Intraneural Lipoma of Digital Nerve

“…Although lipomas are common soft tissue tumors, fingers are not usual sites [ 4–6 ] Intraneural lipomas are extremely uncommon [ 4 ]. Intraneural lipomas arise from the growth of adipose cells within the substance of epineurium.…”

“…Intraneural lipomas are extremely rare in digital nerves with only one other case reported by DeSano et al. [ 4 ]. Their patient had the tumor in right ring finger, however on the ulnar side.…”

A Case of Cervical Intraneural Lipoma That Was Removed by Intercapsular Resection with No Resultant Postoperative Neurological Deficit

“…While lipomas in the cervical region are common, intraneural lipomas in peripheral nerves in this region are extremely rare. Although few cases of intraneural lipomas in the upper limbs have been reported by orthopedists [ 1 , 2 ], to the best of our knowledge, there are no reports of such tumors in the cervical region. We describe here a case that was initially suspected as schwannoma of cervical nerve origin that was finally diagnosed as a cervical intraneural lipoma based on lack of histopathological evidence of schwannoma.…”
