Real-time ultrasonography of the spinal cord: intraoperative and postoperative imaging.

Fourteen subjects with spinal cord pathology were studied with 10 MHz linear array or 5 MHz mechanical sector ultrasound scanners. Twelve patients were studied intraoperatively. The examinations were rapid, aiding the surgeon at the time of exploration. Sonography defined cysts, outlined the extent of neoplasia and aided in the localization of bone fragments. Guidance for placement of syringo -subarachnoid shunts reduced the amount of surgical manipulation. Four patients were examined postoperatively through laminectomy defects, three confirming adequate position and function of shunts and in one case demonstrating tumor recurrence.

The sonographic diagnosis of focal and diffuse infiltrating intrascrotal lesions.

Thirty-six examples of inflammatory and neoplastic disease of the scrotum were evaluated with ultrasound. Analysis of the images suggests that sonographic differentiation of these conditions is possible in certain instances. The ability to separate testicular from extratesticular pathology is quite accurate. In some cases, neoplastic disease of the testis can be differentiated from malignancy, although surgical intervention is often required for diagnosis.

Real-time neurosonography of the brain through calvarial defects with computed tomographic correlation.

Although real-time sonography is an excellent imaging modality for the neonatal brain, examination of the adult brain has been limited. Attempts to study the older subject through the ossified calvarium have resulted in poor quality and non-diagnostic images. Eighteen patients with various calvarial defects were examined for a variety of intracranial abnormalities. A mechanical sector scanner was used. Disease was clearly defined and accurate correlation with computed tomography resulted. Subjects without intracranial disease and patients with cerebral atrophy, porencephalic cysts, hydrocephalus, hematomas, and neoplasia were included in this study. The midline structures, ventricles and proximal midbrain structures were clearly visualized. This procedure appears useful to evaluate changes in the size of the ventricles and intracerebral masses in the postoperative patient.

Unsuspected infectious keratitis in host corneal buttons.

Infectious keratitis may be unsuspected preoperatively in patients undergoing penetrating keratoplasty. We have diagnosed five cases of previously unknown corneal infection discovered only after post-keratoplasty histopathologic examination using specific stains. These cases of preoperatively unsuspected infectious keratitis illustrate examples where histopathologic examination using specialized stains may alert the physician to the need for appropriate postoperative antimicrobial therapy. Furthermore, these cases illustrate the ability of soft contact lenses to mask symptoms of infectious keratitis. Additionally, the clinical appearance of advanced bullous keratopathy may mask signs of infectious keratitis.
