Cubital tunnel syndrome is defined as ulnar neuropathy caused by compression in the region of the cubital tunnel and can be related to a variety of pathological aetiologies. Treatment involves decompression of the nerve and varies depending on the offending agent. We report the case of an 81-year-old man avid tennis player who presented with symptoms related to ulnar neuropathy. The patient was referred for an ultrasound of the elbow which demonstrated ulnar neuropathy related to compression by an 8 mm synovial cyst extending into the cubital tunnel. Magnetic resonance imaging of the elbow was performed confirming the cystic nature of this lesion. Ultrasound-guided aspiration of the cyst was performed followed by injection with corticosteroids. The patient experienced complete resolution of symptoms after treatment.
