Acute Intermittent Porphyria (AIP) the commonest type of porphyria is due to deficiency of porhobilinogendeaminase leading on to accumulation of porphyrin precursors. Clinical diagnosis is often delayed as many of its symptoms mimic other common illnesses. We report a case of 19 year old lady presented to us with quadriplegia, predominantly motor. She also had hyponatremia. In the past she had many symptoms which can occur in AIP,but were overlooked and diagnosis was delayed. This time many past, ongoing and current symptoms like abdominal pain, other autonomic, and neuropsychiatric symptoms were considered together and a clinical diagnosis of porphyria was considered and investigations substantiated it. Diagnosis of AIP require high clinical suspicion and early diagnosis and treatment can prevent recurrence, avoid unnecessary investigations and treatment for many mimickers and will be lifesaving.
