A Mystery Foot Mass - Page #4

Working Diagnosis:
Ganglion Cyst

The patient returned for follow-up after ultrasound and was agreeable to therapeutic and diagnostic aspiration of the cyst. A large amount of clear, jelly-like fluid was aspirated using an 18 gauge needle with almost complete resolution of the mass.

Although the mass resolved following aspiration, it did recur to a much smaller degree about a month later. Surgical excision and/or repeat aspiration of the mass was discussed, but patient declined both.

Author's Comments:
The patient continues with his usual activities, including basketball, and will follow-up only as needed.

Editor's Comments:
This case illustrates the utility of MSK US in the primary care sports medicine setting.
Also, while aspiration of a ganglion cyst may not lead to resolution, in this case, the cyst decreased in size and the patient was reassured about the benign nature of this condition.
