INTRODUCTION.Idiopathic intracranial hypertension is characterized by an increased intracranial pressure, whichpathogenesis is currently unknown. It occurs in 1 to 2 cases per 100 000 habitants; women with overweight or obesity in childbearing age are the highest risk group. Usually, patients do notshow evidence in diagnostic studies that suggests an extensive intracranial process. Clinical features are nonspecific.However,patients can present headache, papilledema and transient loss of vision. Other less common features include photophobia, pulsatile tinnitus, retrobulbar pain, diplopia and permanent loss of vision.
CASE REPORT.A 55 year old obese female with history of untreated hypertension, that began with paralysis of the left side of face, andan occipitalpulsatile headache that later became generalized. The patient also presented, conjunctival hyperemia and decreased visual acuitythat later evolved toa bilateral blindness.
DISCUSSION.An increase in cerebrospinal fluid opening pressure was documented. However,its chemical and staining analysis, as well as the neuroimaging studies,were normal.,The thyroid function tests showed abnormal values, but the rest of the diagnostic studies were negative or normal. The patient was managed with carbonic anhydrase inhibitors, loop diuretics and corticosteroids. The impact on the patient’s life quality, as well as the potential and irreversible damage thatcan occur,if it is not adequately diagnosed and treated,make this case important for the clinician.
