Peripulley ganglion cyst (A1 pulley)
Updates to Study Attributes
There is a thin-walled predominantly anechoic cyst ( 5(5 x 4 x 3 mm) abutting the A1 pulley at the 3rd metacarpophalangeal joint. There is no vascularity in the lesion. The A1 pulley is intact. There is no tendon thickening/ tenosynovitis/tenosynovitis/flexor tendon tear. PalmerPalmar plate is intact. There is no metacarpophalangeal joint effusion. The lesion is free from adjacent neurovascular bundles. Dynamic scaninterrogation shows free tendon movements.
Updates to Case Attributes
Ultrasound findings favor peri A1-A1 pulley gangliaganglion cyst. Peri pulley ganglia Peripulley ganglion cysts are located on the volar aspect of the finger. Location of A1 pulley gangliaganglion cysts is at the metacarpophalangeal joint level and that of A2 pulley ganglia at mid shaftthe midshaft of the proximal phalanx.
