Idiopathic intracranial hypertension (IIH) is a rare disorder of unclear pathogenesis occurring commonly in obese women of childbearing age and characterized by increased intracranial pressure in the absence of intracranial space-occupying lesion or cerebrospinal fluid outflow obstruction. We report a rare case of a middle-aged obese female with intractable headache referred to the department of radiology for neuroimaging on account of suspected dural sinus thrombosis and brain Magnetic Resonance Imaging (MRI) which revealed signs of IIH with asymptomatic transcribriform plate intranasal meningocele with a view to underscore the quiddity of IIH in middleaged obese females and also emphasize the need for radiologists to diligently review previous patient's images where available for possible finding that could contribute to a suspected diagnosis.
