Desmoplastic infantile ganglioglioma (DIG) is a rare brain tumor encountere
d in infants. In spite of its large size at presentation and occasional hig
h mitotic activity on histopathology, the tumor has a good prognosis. A 7-m
onth-old baby girl developed increasing head circumference. On ultrasound,
a large multicystic mass was seen. We report the cranial ultrasound finding
s for the first time. Correlative imaging of this recently recognized entit
y is shown.
