PSEUDOTUMOR CEREBRI IN AN INFANT AFTER L-THYROXINE THERAPY FOR TRANSIENT NEONATAL-HYPOTHYROIDISM

Pseudotumor cerebri is generally a benign disorder. It has been report ed to occur in hypothyroidism, particularly after the initiation of L- thyroxine replacement therapy. Previous case reports have involved chi ldren primarily in the peripubertal age range (similar to 8 to 13 year s). We report here the development of pseudotumor cerebri in an infant who required treatment with L-thyroxine for transient neonatal hypoth yroidism as a result of maternal thyroid-stimulating hormone receptor- blocking antibodies.
