Papilledema and idiopathic intracranial hypertension due to the possible potentiation of ATRA by posaconazole in a case of acute promyelocytic leukemia.
Abstract
Idiopathic intracranial hypertension (IIH) (pseudotumor cerebri) is a rare side effect of all-trans retinoic acid (ATRA). IIH cases have been observed after the concomitant use of ATRA with azole group antimicrobials such as fluconazole and voriconazole. Here, we discuss about the diagnosis and treatment process of the IIH emerging in a young acute promyelocytic leukemia (APL) case with the ATRA impact, which can be increased by posaconazole.
