Abstract
|
|
|
Acute intermittent porphyria (AIP) is a rare genetic disorder. Its clinical manifestations include abdominal pain, neurological symptoms, and sensorimotor polyneuropathy. Herein we report the case of a 23-year-old woman who first presented with abdominal pain, followed by severe sensorimotor polyneuropathy, which was first reckoned as Guillain-Barre Syndrome (GBS) or critical illness polyneuropathy (CIP). Her clinical findings and laboratory data corresponded to AIP, which can cause severe peripheral axonal polyneuropathy, that is, porphyric neuropathy. On the basis of a review of the present case, we confirmed that porphyric neuropathy should be considered as a differential diagnosis in patients with an acutely progressing severe symmetric sensorimotor polyneuropathy with particular similarities to GBS or CIP because considerable recovery can be expected in patients with porphyric neuropathy who receive an early diagnosis and treatment.
