Neuro-Ophthalmological Manifestations after Intramuscular Medroxyprogesterone: A of Idiopathic Intracranial Hypertension?

We report a case of a 22-year-old female student nurse who presented to hospital with an acute neuro-ophthalmological syndrome characterized by papilledema, ataxia, ophthalmoplegia and headache after a single first time use of 150 mg medroxyprogesterone intramuscular injection. Clinical, laboratory, radiological and ophthalmological investigations were in keeping with the diagnosis of idiopathic intracranial hypertension but lumbar puncture did not show a raised cerebrospinal fluid pressure suggesting a of this entity. Her neuro-ophthalmological clinical features responded well to acetazolamide and diagnostictherapeutic lumbar puncture.
