Computed tomography of the gallbladder: unusual diseases.

Abdominal CT has in many cases become the initial radiographic examination to elucidate the cause of obscure abdominal pain, fever of unknown origin, and other difficult diagnostic abdominal problems. Not infrequently, unsuspected disease involving the gallbladder may be encountered. Computed tomography commonly identifies calcified gallstones, occasionally indicates acute cholecystitis, and clearly determines the extent of gallbladder carcinoma. Other less common entities such as gallbladder perforation, porcelain gallbladder, and milk of calcium bile may be diagnosed if suspicion is high and attention directed to anatomic details of the gallbladder and adjacent organs. A review of abdominal CT performed during a 4.5 year period revealed 20 instances of unusual gallbladder diseases in 16 patients. Most often these were encountered incidentally or during CT evaluation of nonspecific abdominal problems.

Problems in CT diagnosis of ruptured abdominal aortic aneurysms.

In a review of 17 cases in which the CT diagnosis of abdominal aortic aneurysm rupture was prospectively made and for which surgical correlation was available the CT diagnosis was correct in 10 and incorrect in seven. Two of the false positives were retrospectively reinterpreted as negative for rupture. Characteristics of 10 surgically confirmed cases revealed a spectrum of appearances not always in agreement with prior published reports, probably due to the age and magnitude of the aortic leaks at the time of diagnosis. The most common characteristic of aneurysm leak (eight of 10 cases) was an abnormal soft tissue collection located adjacent to the posterior aspect of the aneurysm, a sign not previously emphasized in other reports. Renal displacement was also a valuable sign but was present in only three cases, all of which had large hemorrhages. Other characteristics of aortic rupture such as density of the collection and sharpness of its margins were not found to be generally useful.

Variable CT appearance of plasma cell granuloma of the lung.

Plasma cell granuloma of the lung is an uncommon benign inflammatory pseudotumor. Although it typically presents as a solitary mass on chest radiography, several chest film appearances have been described. Three cases are presented that illustrate the variable range and nonspecificity of CT appearances of plasma cell granuloma of the lung. Computed tomography is useful in the evaluation of these lesions primarily to establish important anatomic relationships associated with each of the various manifestations.

Tertiary syphilis of the liver: CT appearance.

A case of tertiary syphilis is reported in which CT demonstrated liver involvement. There were calcifications in the liver indistinguishable from hepatic calcifications due to other diseases. Syphilitic gummata should be considered in the differential diagnosis of liver calcifications when the clinical history is appropriate.

Orbital implants and prostheses: postoperative computed tomographic appearance.

Computed tomographic (CT) scans of 19 patients with 10 right and nine left orbital implants were reviewed. Except for orbital soft-tissue swelling due to recent surgery or infection, CT scans obtained with both the implant and prosthesis in place showed relative symmetry of the postoperative side and the native globe. Benign air collections were often associated with either the implant or prosthesis interface or with seating of the prosthesis in the conjunctival fornices. Six patients had either cartilage, silicone, or glass beads placed surgically along the orbital floor to elevate the implants, four having had prior depressed orbital floor fractures. CT identified implant migration in five patients. The orbital prosthesis, usually constructed of solid methylmethacrylate, is fitted over the implant and simulates the appearance of the eye of the contralateral side. The operative anatomy and its relation to the CT appearance of the implant and external prosthesis are reviewed.
