Comparison of MR imaging, CT, and angiography in the evaluation of the enlarged cavernous sinus.

Twenty-one patients with enlargement of the cavernous sinus were studied with CT and MR imaging. Eighteen of the patients also had cerebral angiography. MR was superior to CT in differentiating parasellar aneurysms from neoplastic masses. MR was also superior to both CT and angiography in defining the relationships of cavernous sinus neoplasms to the internal carotid artery, pituitary gland, optic chiasm, infundibulum, and fifth cranial nerves. Only in the definition of bone erosion or hyperostosis was MR inferior to another method (CT). We conclude that MR should be the initial diagnostic study in patients with symptoms of a parasellar mass, with supplementation when necessary by CT and angiography.

Intervertebral disk-space infection after chymopapain injection.

Four patients who had received chymopapain injections for treatment of herniated lumbar disks were evaluated by computed tomography (CT) because of persistent low back pain and suspicion of infection. Irregularity of the vertebral end-plate and a mottled appearance of the vertebral bodies suggested the diagnosis of disk-space infection in all four cases. CT-guided biopsy of the disk space was performed in each case, and bacterial cultures demonstrated staphylococcal infections, which were treated accordingly. Diskitis secondary to chymopapain injection is rare because of the precautions that are usually taken. No antibiotics are used routinely with such injections, although systemic antibiotics have been used in diabetics for prophylaxis.

Computed tomography of spine trauma.

Nine patients admitted to the hospital for spine trauma were studied with computed tomography. The use of computed tomography minimized patient motion, allowed excellent definition of compromise of the spinal canal by fracture fragments, and better delineated fractures of the neural arches than plain films or tomography. Plain radiographs and computed tomography scans permitted complete evaluation of spine trauma with no additional investigations being necessary.

Computed tomography in acute head injuries.

Computed tomography (CT) is ideally suited for detection of intracranial pathology, whereas plain radiography is limited to the bony structures. Distinguishing surgical and nonsurgical lesions is quite feasible with CT. Follow-up examinations are non-traumatic and carry minimal risk to the critically ill patient. In the great majority of head trauma cases, the recognition of pathology is unequivocal, thus facilitating proper management.

Ultrasonographic abdominal aortography.

B-mode ultrasonography is an easily performed and accurate method of studying the abdominal aorta. The procedure is totally noninvasive and does not require patient hospitalization to detect aortic aneurysmal dilatation. Aneurysm size, extent, and associated aneurysmal clot formation can be determined more accurately than with contrast aortography. Para-aortic abdominal masses or organs that transmit pulsations can be detected where an aneurysm was originally suspected. Studies for serial size determination or postoperative follow-up are quickly and inexpensively performed, making this procedure the choice diagnostic modality for abdominal aortic aneurysms.
