Meckel's diverticulum. Internal hernia and adhesions without gastrointestinal bleeding--ultrasound and scintigraphic findings.

The results from an ultrasound study performed on an 11-year-old boy, who had several weeks of intermittent abdominal pain, showed a nonperistaltic loop of bowel near the umbilicus, which suggested either an internal hernia or a diverticulum. Tc-99m pertechnetate imaging showed a focal collection near the umbilicus, which was consistent with a Meckel's diverticulum. No evidence was found of gastrointestinal bleeding. Exploratory laparotomy showed a Meckel's diverticulum near the terminal ileum and attached to the anterior abdominal wall close to the umbilicus. Small bowel had herniated through the loop formed by the terminal ileum and the diverticulum.

Gallbladder perforation. An imaging analysis.

We evaluated the radiologic studies of 23 patients with surgically or autopsy-documented gallbladder perforation. Extravasation was shown by cholescintigraphy and cholangiography in seven patients and corresponded to free perforation or large pericholecystic loculation. In 16 patients, ultrasonography and computed tomography detected fluid and abscesses outside the gallbladder ranging from 1 to 2 mm pericholecystic fluid collections to large phlegmonous masses. A right, upper-quadrant mass on plain films and scattered calcification in this area suggested perforation. Gallbladder perforation could be diagnosed or suspected preoperatively in ten patients and antemortem in 22 of 23 individuals. This rate of recognition, higher than previously reported, may be ascribed in part to improvements in biliary imaging.

Radioisotope bone scanning in a case of sarcoidosis.

The application of radioisotope scanning to osseous involvement from systemic sarcoidosis has been infrequently described in the scientific literature. Most commonly, the small bones of the hands and feet are affected if sarcoidosis involves the skeleton. Nonetheless, there are also occasional manifestations of sarcoid in the skull, long bones, and vertebral bodies. This paper describes a case of sarcoid involving the lung parenchyma with multiple lesions in the skull and ribs demonstrated by bone scanning with Tc-99m MDP. Following treatment with steroids, the bone scan showed complete resolution of the rib lesions and almost complete resolution of the lesions in the calvarium.

Abdominal manifestations of actinomycosis in IUD users.

The use of an intrauterine device (IUD) is associated with the presence of actinomyces in the female genital tract. Since IUD use is currently so prevalent, IUD-related pelvic inflammatory disease occasionally spreads to the rest of the abdomen. Two patients with abdominal actinomycosis in association with an IUD illustrate the problem; we review the general problem.

The association of cleidocranial dysostosis with hearing loss.

Three new cases of cleidocranial dysostosis with hearing loss are reported in this paper. The significant points concerning this association are: (1) the hearing deficit is predominantly a middle ear conduction problem secondary to structural abnormalities of the ossicles; (2) there is sometimes a small bone conduction deficit indicating either a cochlear or an eighth nerve problem; (3) the middle ear hearing loss was corrected surgically in one reported case; (4) there is dense sclerosis of the temporal bone which makes a middle ear operation technically difficult; and (5) hearing loss with cleidocranial dysostosis may be more common than the number of cases in the literature suggests.
