All-trans-retinoic acid and pseudotumor cerebri in a young adult with acute promyelocytic leukemia: a possible disease association.

Pseudotumor cerebri or idiopathic intracranial hypertension is a neurological syndrome characterized by signs and symptoms of intracranial hypertension without clinical or radiological evidence of infective or space occupying lesions. Iatrogenic factors are frequent; in particular, cases of pseudotumor cerebri associated with all-trans-retinoic acid treatment in acute promyelocytic leukemia (APL) have been frequently described in pediatric patients. We report on a case observed in an older patient (young adult age) and give diagnostic and therapeutic guidelines.
