Abstract

Posterior interosseous nerve (PIN) syndrome is a condition defined by compressive neuropathy of this radial nerve branch caused by trauma, space-occupying lesions, brachial neuritis, or spontaneous compression. Its clinical presentation is characterized by an insidious onset of symptoms, usually a deficit in finger extension without sensitive impairment. In the present article, we report a clinical case of a 72-year-old female with an intraneural lipoma that had been causing extrinsic compression for 11 months, and had a full recovery after surgical excision. Besides the paucity of clinical cases described in the literature (only three to date) we also emphasize the excellent outcome of the patient, regardless of her age and of the duration of symptoms.

Keywords

PIN - posterior interosseous nerve syndrome - intraneural lipoma - lipoma
