A case report on rare occurrence of periosteal ganglion cyst in femoral intercondylar region

Abstract

Ganglions are the cysts derived from myxomatous degeneration of periarticular tissue, commonly found around wrist and foot. Ganglion cysts are uncommon in Knee region and if present their occurrence is mostly incidental and benign. Based on their location, this could be extraarticular or intraarticular. Lesions with similar pathology in subchondral region around joints are lesser common entity called Intraosseous ganglions. Rarer still is the lesion produced by myxomatous degeneration of periosteum of long bone, called periosteal ganglion. We here present a case of 35 year old Male with gradual onset, poorly localised pain behind left knee which was radiologically suggestive of periosteal ganglion, eroding the posterior aspect of femur and confirmed histopathologically following the excision of a lesion from posterior aspect of femoral condyles.

Periosteal ganglion cyst of tibia: A rare case report

“…The recurrence rate for ganglion cysts is generally estimated to be between 15 % and 20 % [ 12 , 13 ]. Prevention for periosteal ganglion cysts include avoiding occupational hazards that has risk of injuring the joint or resting the wrists and fingers after long time of exertion [ 14 ]. This study has been reported in line with the SCARE criteria [ 15 ].…”
