Traction injuries of the brachial plexus: signal intensity changes of the posterior cervical paraspinal muscles on MRI.

PURPOSE: Our goal was to evaluate MR signal intensity change of the posterior cervical paraspinal muscles in brachial plexus traction injuries to determine the value of this finding in the diagnosis of nerve root avulsion. METHOD: MR images of 11 consecutive patients, 7 with nerve root avulsion and 4 without nerve root avulsion, were retrospectively analyzed, focusing on the signal intensity of the paraspinal muscles. RESULTS: Among the seven patients with nerve root avulsion, T2- or T2*-weighted MR images showed increased signal intensity in the deep posterior paraspinal muscles in five and traumatic meningocele in four. The signal intensity of the posterior paraspinal muscles was normal in all patients without nerve root injuries. CONCLUSION: MR signal intensity change in the deep posterior cervical paraspinal muscles is related to denervation and suggests the presence of nerve root avulsion.

Peripheral nerve intraneural ganglion cyst: MR findings in three cases.

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.

MR assessment of meniscal movement during knee flexion: correlation with the severity of cartilage abnormality in the femorotibial joint.

PURPOSE: The purpose of this study was to assess the degree of meniscal movement during knee flexion on MR images and to correlate it with the severity of cartilage damage in the femorotibial joint. METHOD: Sagittal MR images were obtained at extension and 45 degrees of flexion in 35 knees. A shortening ratio in the distance between the anterior and posterior horns at 0-45 degrees of knee flexion was calculated in each meniscus and was correlated with the degree of cartilage abnormality in the femorotibial joint. RESULTS: The shortening ratio of the meniscus was reduced in knees with cartilage abnormality in the femorotibial joint. The shortening ratio of the medial meniscus was inversely correlated with the degree of cartilage abnormality in the medial femoral condyle and with that in the medial tibial plateau. CONCLUSION: Restricted shortening ratio of the meniscus may be related to cartilage damage in the femorotibial joint.
