A cerebral midline cystic lesion was detected by real-time ultrasound in utero in the absence of other congenital abnormalities. Pulsed Doppler ultrasound assessment of fetal circulation demonstrated ...normal peripheral and intracardiac hemodynamics associated with decreased cerebral vascular resistance. Furthermore, a markedly turbulent flow pattern was evidenced within the cerebral lesion. The presence of a cerebral arteriovenous malformation with an aneurysm of the vein of Galen was suggested and the provisional diagnosis was later confirmed by computed tomography and carotid angiography performed after birth.

Both penetrating and blunt cardiac injuries require urgent management. Delayed sequelae and complications have been reported to occur in 4 to 56% of survivors and frequently required secondary ...surgical corrections. Between January 1980 and June 1984, 204 patients presented with heart injuries. One hundred twenty-eight of these patients survived. Of the 90 undergoing cardiorrhaphy in the operating room, 78 survived. Two-dimensional (2-D) and pulsed-Doppler echocardiography (echo) and/or cardiac catheterization were performed in 40 patients for suspected significant residual injury. Eight of the 40 required secondary cardiac operations. Two-dimensional echo demonstrated pericardial effusion, abnormal chamber enlargement, abnormal cardiac wall motion, intracardiac missile, and intracardiac and pleural thrombus. Pulsed-Doppler findings included ventricular septal defect, tricuspid insufficiency and right ventricular turbulence secondary to arteriovenous fistulae. Cardiac catheterization detected lesions undetected by 2-D echo in one patient with a gunshot wound. It is concluded that in the absence of cardiac bullets seen on routine chest X-ray, 2-D with pulsed-Doppler echo is an excellent screening technique. With a positive echo study or a residual bullet overlying the cardiac silhouette, cardiac catheterization is indicated in selected patients.
