Summary::
Posterior Reversible Encephalopathy Syndrome is a rare and
acute neuro-radiological entity, characterized by several
symptoms of different aetiologies. The main etiologies of
PRES are HTN, Pre-eclampsia, Eclampsia,
Immunosuppressive therapy etc, but there are many
unexplained causes too. Here we report a case of post-partum
woman who developed PRES in post-operative period, who
was complicated by the postdural puncture headache
following spinal anesthesia- a rare and uncommon etiology.
