Computed tomography in the diagnosis of congenital cytomegalic inclusion disease.

We present two cases of congenital CID, one in a 4-month-old male infant and the other in a 6-week-old male infant. The diagnoses were confirmed by means of computed tomography, cultures, and serologic methods. The relatively noninvasive character of CT makes it an ideal diagnostic method in the neonate. With the improved visualization afforded by CT, specificity on radiographic grounds alone may become possible.

Comparison of arachnoiditis produced by meglumine iocarmate and metrizamide myelography in an animal model.

Myelography in monkeys was performed with either meglumine iocarmate or metrizamide. The severity of resultant arachnoiditis in each animal 12 weeks later was evaluated by repeat myelography and by histologic study of the arachnoid. Three of the four animals examined with meglumine iocarmate had severe arachnoiditis; none of the four animals examined with metrizamide had as severe changes. The difference between the two groups was statistically significant (P less than .05).

Traumatic bilateral carotid-cavernous sinus fistulas with progressive unilateral enlargement.

The authors present a patient with traumatic bilateral carotid-cavernous sinus fistulas associated with fracture of the sella turcica. Repeat angiography ten days after admission revealed that the left fistula had enlarged and was shunting the entire output of the left carotid artery and a portion of the output of the basilar artery. A muscle embolization procedure was sucessfully performed on the left side but was complicated by hemorrhage from the left cavernous sinus prior to closure. Problems associated with the enlargement of carotid-cavernous fistulas are discussed.

Experimental production of arachnoiditis with water-soluble myelographic media.

After myelography with either metrizamide (300mg l/ml) or meglumine iocarmate (280 mg l/ml), mild to severe arachnoid fibrosis was demonstrated radiographically and histologically in primates. Intrathecal injections of metrizamide (170 mg l/ml) or autologous cerebrospinal fluid produced less arachnoiditis. The risk of arachnoiditis is probably minimized by the use of reduced volumes and concentrations of water-soluble media. Controlled studies of arachnoiditis following myelography are probably more reliable in the primate model than in other experimental animals.

Arachnoiditis following myelography with metrizamide in monkeys. Effect of blood in the cerebrospinal fluid.

Monkeys were injected intrathecally with blood, metrizamide (Amipaque) or a mixture of blood and metrizamide. Twelve weeks later the animals were examined for evidence of arachnoiditis. Either blood or metrizamide alone in sufficient amounts resulted in arachnoiditis. The addition of blood to metrizamide did not alter the severity or risk of arachnoiditis from experimental myelography with metrizamide.

Double contrast myelography.

Myelography was performed with a combination of air and an aqueous myelographic contrast media. Excellent demonstration of the arachnoid sac and cord was possible with double contrast myelography in primates. A technique for double contrast myelography is described. Clinical applications are discussed.
