POSTERIOR TIBIAL NEUROPATHY FROM RUPTURED BAKERS CYST

Objectives: To increase awareness of entrapment neuropathy caused by r upture of Baker's cyst. Methods: A patient with psoriatic arthritis, r uptured Baker's cyst, and entrapment neuropathy is reported and the li terature on this complication is reviewed. Results: Nerve entrapment c aused by rupture of Baker's cyst is rare. Neurological examination and demonstration of Baker's cyst by Color Doppler Duplex Ultrasound (CDD U) help in making the diagnosis. Nerve Conduction Study (NCS) may conf irm the diagnosis of posterior tibial nerve entrapment. Conclusions: P eripheral nerve entrapment should be considered in patients with Baker 's cysts and loss of sensation along the plantar aspect of the foot or other neurological symptoms or findings.
