Histological features of a subject of 28 weeks gestation who died. Histological features of a subject of 28 weeks gestation who died. (A) Typical frontal horn cysts on ultrasound; (B) histological features of part of the cyst showing no distortion of surrounding tissues (a) and ventricular wall (b). There is no evidence of haemorrhage in or around the cyst. The cyst is lined by nodules of neuroblasts which project into the lumen of the cyst (c) and occasional blephoroplasts, suggesting an ependymal origin. (C) Magnification of the cyst showing neuroblastic focus similar in appearance to normal germinal matrix. B R Pal et al.
