Post Dural Puncture Headache after Diagnostic Lumbar Puncture in a Male Patient with Intra-cranial Hypertension

Idiopathic Intra-cranial Hypertension (IIH) is characterized by elevated intracranial pressure in the absence of a cranial mass or other disease process. Elevated intracranial pressures are hypothesized to result from an increased cerebrospinal fluid production, decreased reabsorption, or cerebral edema. Our patient illustrates a paradoxical change in intracranial pressure after diagnostic lumbar puncture for evaluation of IIH.
