Benign intracranial hypertension associated with hypothyroidism in a hemophilic child

Benign intracranial hypertension (BIH) due to hypothyroidism in children is rare. We report a case of BIH due to hypothyroidism with bilateral sixth nerve palsy in a hemophilic child. The child presented with headache, vomiting, and inward deviation of both eyes for 10 days. On examination, her vision was 20/40 both eyes with restricted abduction in both the eyes. Anterior segments were within normal limits. Fundus showed bilateral disc edema. No marked abnormality was detected by neuroimaging. Baseline investigations were normal except a raised thyroid stimulating hormone. We started the patient on tablet acetazolamide, domperidone, and systemic steroids. Disc edema and ocular movements started improving. We have not come across any such case in literature after thorough PubMed search. The presentation, management, and future problems of this rare case are discussed.
