Abstract

A 5-month-old boy presented with bilateral hydroceles since birth and right leg edema. An ultrasound of the pelvis showed a 4-cm cystic mass that was diagnosed as a teratoma or cystic hygroma. Magnetic resonance imaging was performed, which showed a dumbbell shaped contiguous, fluid filled mass extending intraabdominally through the inguinal canal from the scrotum. The cystic portion in the right iliac fossa was lying on the right iliac vessels, which were patent. A bilateral hydrocelectomy was performed, and the intraperitoneal sac was completely excised through the inguinal incision. The edema of the right leg disappeared a few days after surgery.

Abstract

Postoperative magentic resonance imaging (MRI) of basal ganglia functional lesions illustrates the accuracy of preoperative target localization. The technique of perioperative MRI and CT localization for pallidotomy will be discussed and correlated with the center of the lesion on postoperative standard MRI as well as three-dimensional (3-D) volume acquisition of image. Using a 1.5-tesla Signa system, a conventional acquisition of 128-slice, 256 x 256 matrix spoiled grass (SPGR) images were used for 3-D reformation. This allowed approximately 1 x 1 x 2 mm resolution over a 24-cm field of view in a T-1-weighted image. The display affords a volumetric analysis of the anatomic location and relation of the post-ventral pallidotomy to adjacent structures. Accuracy of lesion placement based on perioperative MR coordinates and revealed on postoperative images is confirmed. The volume of the lesion as well as its location are factors that affect clinical outcome.

Abstract

Magnetic resonance imaging technique is an exciting, new, safe clinical tool that provides a noninvasive way to monitor free-tissue transfers. Magnetic resonance imaging (MRI) produces a cross-sectional tomographic image at higher resolution than conventional CAT scans and provides a dynamic and physiologic assessment of transferred tissue. We first studied ischemic muscle in the beagle hindlimb gracilis muscles and found an incremental and definitive increase in signal strength both over time and in comparing complete devascularization to partial devascularization. In the right hindlimb (partially devascularized), there was an average increase in T2 (measured in milliseconds) of 2.5 percent at 1 hour, 16.72 percent at 3 hours, and 16.45 percent at 12 hours as compared to normal undisturbed muscle. Similarly, the left hindlimb (completely devascularized) measurements increased from 10.97 percent at 1 hour to 24.02 percent at 3 hours to 47.75 percent at 12 hours. Possible explanations for T2 increases include an increase in intercellular and intracellular water, a change in pH, and possible protein metabolism changes. Clinical studies in seven patients with free flaps have shown "normal" T2 values in healthy tissue comparable to undisturbed canine gracilis muscle and the change in contour and composition of tissue over time. The clinical usefulness of these data is apparent.
