Conclusion

This case reviewed the presentation, work-up, and treatment of PIN palsy caused by a lipoma. As radial nerve paralysis is most commonly caused by orthopedic and iatrogenic trauma, the case highlights the importance of a thorough physical exam and suspicion of a deep causative mass in the case of an unclear clinical presentation of radial nerve palsy. Aided by the MRI diagnosis of lipoma, the symptomatic mass was excised, allowing for the patient's swift and progressive recovery.
