BACKGROUND Intraosseous ganglion (IOG) cysts rarely have been reported in the carpal bones and lunate is the most common area of involvement. They can present as chronic wrist pain accompanied by a radiolucent lytic lesion in the lunate bone. We provided a retrospective review of six cases of intraosseous ganglion cysts within the lunate bones that all of the patients presented with chronic wri...

This article reviews what is known about ganglion cyst formation, natural history (50% of cysts will spontaneously resolve), diagnosis, and management of this common malady. Although the exact mechanism of cyst formation is unknown, most current theories hold that extra-articular mucin "droplets" coalesce to form the main body of the tumor. Only subsequently are the "cyst wall" and pedicle (con...

Fig. 1.Axial MR images at level of mandibular condyles. nounced during Valsalva. There was no evidence of adenopathy or bruit, nor was there evidence of paresthesia or motor deficit. Oral examination was normal. MR imaging demonstrated bilateral cystic structures just anterior and lateral to the mandibular condyles (Figs. 1 and 2). CT before and after right temporomandibular joint arthrography ...

Ganglion and synovial cysts occur mainly, but not necessarily, in association with osteoarthritis. Presentation varies widely, ranging from small, incidentally detected, asymptomatic lesions to giant ones that might be the source of symptoms, either due to their compressive effect on adjacent structures or due to complications, such as rupture. On magnetic resonance imaging they are typically p...

Lesions of the ulnar nerve are the most common causes of paralysis of a peripheral nerve.1,2 The cubital tunnel (or sulcus ulnaris) syndrome is the second most frequent compression syndrome of the upper extremities after the carpal tunnel syndrome.3,4 We report our findings in a patient who suffered from cubital tunnel syndrome and underwent subcutaneous anterior transposition, a surgical proce...

Background A ganglion is a common benign cystic lesion, containing gelatinous material. Ganglia are most commonly asymptomatic, except for a lump, but symptoms depend on the location. A dorsal foot ganglion is typically painful. On the dorsal foot, the dorsalis pedis artery and the medial branch of the deep peroneal nerve are located under the fascia. Objective Five female patients of average...

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...
