MRI Findings of Causalgia of the Lower Extremity Following Transsphenoidal Resection of Pituitary Tumor
Figure 1
(a) and (b) Initial MRI of the lower extremities demonstrates edema in the right semimembranosis and semitendinosis muscles with abnormal enhancement in the distal sciatic and common peroneal nerves. (c) and (d) Delayed MRI of the lower extremities demonstrates near resolution of edema in the muscle and normalization of the nerves without abnormal enhancement.
