We present MR findings of three cases of surgically proved intraneural ganglion cysts involving the common peroneal nerve (two patients) and ulnar nerve (one patient). The lesions were located along the course of the involved nerve and situated close to a joint. MRI demonstrated the cystic nature and extent of the lesions with clear definition of the anatomic relationship of the lesions to the surrounding structures.
The radial head fracture combined with the dislocation of the distal radioulnar (RU) joint which is called Essex-Lopresti injury is very rare. We report one case of this injury. A twenty-four years old man fell down on his right palm in a motorcycle accident. He visited his local G.P. and the fracture of the radial head and dislocation of the distal RU joint was pointed out. Two days after injury, resection of the radial head was carried out but a reduction of the distal RU joint was impossible. Five weeks after injury, he visited our hospital because of wrist pain and a limitation of supination-pronation. We planned Sauve-Kapandji's operation however, the movement of his forearm gra
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
