Leriche Syndrome: Acute Onset Painful Paraplegia of Vascular Origin with Catastrophic Consequences.

Acute Aorto-Iliac Occlusive Disease (AIOD) is a rare clinical entity which when presents with buttock claudication, erectile dysfunction and absent femoral pulses is termed as Leriche syndrome. A 59-year-old male patient with past history of smoking and dyslipidaemia presented with acute onset lower back pain, paraplegia, intense lower limb pain and was initially evaluated for compressive myelopathy. On further clinical examination there were absent femoral pulses and Computed Tomography (CT) aortogram was done which confirmed the diagnosis of diffuse AIOD. Clinically, it is often challenging to differentiate between vascular or neurogenic origin of acute onset painful paraplegia. A high index of suspicion and careful clinical examination is therefore essential to avoid misdiagnosis of a major vascular event which can result in significant morbidity and mortality.
