Proximal Sciatic Nerve Intraneural Ganglion Cyst
نویسندگان
چکیده
Intraneural ganglion cysts are nonneoplastic, mucinous cysts within the epineurium of peripheral nerves which usually involve the peroneal nerve at the knee. A 37-year-old female presented with progressive left buttock and posterior thigh pain. Magnetic resonance imaging revealed a sciatic nerve mass at the sacral notch which was subsequently revealed to be an intraneural ganglion cyst. An intraneural ganglion cyst confined to the proximal sciatic nerve has only been reported once prior to 2009.

Pure peroneal intraneural ganglion cyst ascending along the sciatic nerve.
Peroneal nerve entrapment is most commonly seen in the popliteal fossa. It is rarely caused by a ganglion. Intraneural ganglia, although uncommon and seldom cause serious complications, are well recognized and most commonly affect the common peroneal (lateral popliteal) nerve. Ganglionic cysts developing in the sheath of a peripheral nerve or joint capsule may cause compression neuropathy. The ...
متن کاملTeaching NeuroImages: intraneural ganglion cyst of the tibial nerve.
A 59-year-old man with knee arthritis suddenly developed left posterior thigh pain and complete paralysis of his foot. EMG/nerve conduction studies localized the lesion to the distal sciatic nerve in the thigh (absent motor units from the short head of biceps femoris but normal vastus lateralis). Imaging demonstrated an intraneural ganglion cyst in the tibial nerve extending up to the sciatic n...

Peroneal intraneural ganglion cyst which manifests itself with the complaint about palpable swelling and pain around the knee laterally adjacent to fibula neck, that peroneal nerve passes through, is a pathology that can lead to neurological symptoms. For the diagnosis of peroneal intraneural ganglion cyst, which is a rare reason for drop foot, physical examination, electromyography and radiogr...
متن کاملCommon Peroneal Nerve Palsy Secondary to a Proximal Tibiofibular Joint “Ganglion Cyst”—A Case Report and Review of Literature
Although ganglion cysts occur frequently, their presence in the lower extremities is rare and they seldom cause peripheral nerve compression. There are enumerable case reports of intraneural ganglion involvement with the common peroneal nerve and its branches, the sural nerve, and the posterior tibial nerve but extraneural ganglion sciatic and common peroneal nerve palsy cases are quite rare. O...
