✦ Synopsis
Urea cycle disorders (UCDs) are rare causes of hyperammonemic encephalopathy in adults. Most UCDs present in childhood and, if unrecognized, are rapidly fatal. Affected individuals who survive to adulthood may remain undiagnosed because of clinicians' unawareness of the condition or atypical presentations. We describe the case of a 49-year-old man who initially presented with a stroke and developed hyperammonemic encephalopathy over a period of 8 months. A diagnosis of carbamoyl phosphate synthetase type 1 deficiency was made, and the patient was referred for liver transplantation. One year after liver transplantation, the patient had normal plasma ammonia concentrations and had returned to work. Liver Transpl 17:1481-1484, 2011. V C 2011 AASLD.
