When the Scar Speaks: Multimodality Imaging of a Post-Traumatic Neuroma
Abstract: Post-traumatic neuromas are benign, non-neoplastic lesions that arise from disorganized nerve regeneration following peripheral nerve injury. Although, uncommon, they are an important cause of persistent pain, paresthesia, and functional impairment after trauma, often mimicking other soft tissue lesions and posing a diagnostic challenge. We present the case of a 32-year-old male who developed persistent pain, paresthesia, and extension deformity of the left index and middle fingers following a penetrating glass injury to the left hand that had been managed conservatively. Clinical examination revealed a tender palpable nodule along the course of the median digital nerve with a positive Tinel?s sign. High-resolution ultrasonography demonstrated a well-defined hypoechoic lesion in continuity with the affected nerve, showing loss of normal fascicular architecture and no internal vascularity. Magnetic resonance imaging further characterized the lesion as isointense on T1-weighted images and hyperintense on T2-weighted images with minimal post-contrast enhancement, findings highly suggestive of a traumatic neuroma. Electromyography and nerve conduction studies revealed severe left-sided median nerve sensorimotor axonal neuropathy, supporting the diagnosis. Correlation of the patient?s clinical history with multimodality imaging findings enabled accurate diagnosis and exclusion of other peripheral nerve sheath tumors. This case highlights the pivotal role of high-resolution ultrasound and magnetic resonance imaging in the evaluation of post-traumatic peripheral nerve lesions. Early recognition of characteristic imaging features is essential for timely diagnosis, appropriate surgical planning, symptom relief, and prevention of long-term functional disability.
