	*Contributor:*	Nikolaos Sferopoulos, MD
	*Description:*	5 cm cystic mass

	*Diagnosis:*	CYST, SYNOVIAL / CYST, RETROCALCANEAL	*Category:*	lumps & bumps (plaques, nodules, tumors) / orthopedic disorders
	*Body Site:*	heel / foot	*Age:*	63 years
	*Contributor:*	Nikolaos Sferopoulos, MD
	*Description:*	bilateral 5 cm cystic masses
	*Comments:*	This 63-year-old man had asymptomatic swelling of the back of his ankles consistent with retrocalcaneal cysts. Retrocalcaneal cysts are usually associated with retrocalcaneal bursitis resulting from local trauma from poorly designed shoes or activities that result in recurrent trauma to the ankle such as roller and ice skating and long distance running. The patient complains of posterolateral heel pain, particularly with passive dorsiflexion or resisted plantar flexion. A posterior heel prominence, local swelling and tenderness at the medial or lateral aspect of the Achilles tendon insertion is indicative of retrocalcaneal bursitis.
