A 38-year-Old Woman With Flaccid Tetraparesis after Presenting With Abdominal Pain

A 38-year-old woman presented in the emergency department with acute abdominal pain. She underwent laparoscopic cholecystectomy. Postoperatively, she developed worsening abdominal pain, tachycardia, flaccid tetraparesis, urinary retention, constipation and SIADH. She also developed red-colored urine. Porphobilinogen was requested in an isolated urine sample, with the test result showing 256 mg/g of creatinine. This case didactically emphasizes the necessity of considering differential diagnosis in acute abdomen pain associated with neurological disorders.
