ABSTRACT
A large perirectal mucocele developed in a child over an 11-year period following repair of an imperforate anus. Renal failure and large bowel obstruction secondary to compression by the mass were the presenting symptoms. Computed tomographic evaluation of the pelvis was critical for preoperative assessment of this previously unreported complication of imperforate anus repair.

The sonographic appearance of kidneys in patients presenting with acute renal failure due to hemolytic-uremic syndrome (HUS) was evaluated and compared with that in an age-matched control series. In nine patients with HUS, the renal cortex was typically hyperechogenic and the renal pyramids appeared sonolucent. The renal size was normal or enlarged compared with 35 normal controls. While not specific, the sonographic patterns described in this study support the diagnosis of HUS in the appropriate clinical setting.

We used technetium Tc 99m medronate (methylene diphosphonate) scanning in the treatment of seven patients with rhabdomyolysis. In three patients the intense, diffuse, symmetric nature of the scans was suggestive of an underlying metabolic muscle disorder. The scans defined the extent of the muscle injury in three patients and demonstrated muscle injury that was not initially suspected in two patients. The scan also demonstrated clinically unsuspected metastatic pulmonary and gastric calcifications in one patient. All scans showed evidence of renal dysfunction. In conclusion, these cases demonstrate that Tc 99m medronate scanning helps to define the extent and location of muscle injury in rhabdomyolysis, and that diffuse muscle uptake of Tc 99m medronate may be associated with metabolic muscle disease.

Methyl iodide-131 (CH3I-131) is described as an agent for detection of acute experimentally produced pulmonary arterial occlusion in dogs. When gaseous CH3I-131 is inhaled, radioactivity passes instantaneously from the alveoli to the lung capillary bed. Where pulmonary blood flow exists, activity is washed out into the systemic circulation, but in areas of blood stasis, a transient pulmonary "hot spot" remains. CH3I-131 is easily produced and inexpensive, but administration is awkward and strict radiation safety precautions are mandatory.
