Abstract

Twenty-five patients underwent bedside ultrasonographic examination through a postoperative skull defect, and the images were compared with axial computed tomography (CT) scans. The patients included 12 with cerebrovascular disease, two with brain tumor, one with a brain abscess, and 10 with head injury. Clear ultrasonographic images were obtained in all patients except one who had undergone a suboccipital craniectomy. Ultrasound was most useful when hydrocephalus was present, in which cases, regardless of the cause, hypo-echoic dilated third and lateral ventricles were demonstrated. In one case, it was decided to emplace a ventriculoperitoneal shunt on the basis of the results of serial sonography, which documented ventricular enlargement. Intracerebral hematomas also were identified by ultrasonography. Acute hematomas, such as subarachnoid blood clots persisting after clipping of an aneurysm, appeared as hyper-echoic images, whereas, late hematomas were depicted as hypo-echoic images. In one case, a recurrent brain tumor was depicted as a hyper-echoic mass. In multiple-trauma patients with head injury who were too unstable to be moved for CT scanning, ultrasound was extremely useful. So-called "delayed traumatic intracerebral...Continue Reading

Brain Abscess

Brain abscess is an accumulation of pus caused by inflammation and infected materials in the brain. Symptoms include fever, headache, seizures and other neurological problems. Discover the latest research on brain abscess today.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Cardiomegaly

Cardiomegaly, known as an enlarged heart, is a multifactorial disease with different pathophysiological mechanisms. Hypertension, pregnancy, exercise-induced and idiopathic causes are some mechanisms of cardiomegaly. Discover the latest research of cardiomegaly here.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
