A Giant Atypical Baker's Cyst Causing Compressive Neuropathy of Combined Peroneal and Tibial Nerves - A Case Report.

Introduction: Popliteal cysts (Baker cysts) causing compressive neuropathy of combined tibial and common peroneal nerves is an exceptional entity. Especially, an isolated multi-septate unruptured cyst (usually posteromedially) dissecting posterolaterally, thereby causing compression of multiple components of the popliteal neurovascular bundle as seen in this case report is unique in clinical field and in the literature. Awareness and early diagnosis of such cases along with a prudent technique will preclude permanent impairment.
