Waxing and Waning Presentation of Isolated Cardiac Sarcoidosis on Sequential 18F-FDG PET Examinations.

We describe the case of a patient who had suspected myocardial ischemia, showed normal findings on multiple perfusion scans, and showed isolated cardiac sarcoidosis on 18F-FDG-PET. Also discussed are the diagnosis and the monitoring of disease response using imaging follow-up.

Focal angiomatosis of the breast with MRI and histologic features.

Angiomatosis of the breast is an extremely rare, benign vascular lesion. This is a diagnostic challenge, given the limited number of cases reported in the literature. Additionally, due to similar features of the more common malignant vascular tumor, angiosarcoma familiarity with angiomatosis in the differential diagnosis is important. We present a case of angiomatosis of the breast in a 28-year-old female. The lesion presented as an incidental enhancing mass on computed tomography scan initially and subsequent mammogram and ultrasound studies did not show a correlate. Next, magnetic resonance imaging demonstrated an enhancing correlate for which magnetic resonance imaging biopsy and subsequent excisional biopsy demonstrated angiomatosis of the breast.

Jejunal diverticulosis found in a patient with long-standing pneumoperitoneum and pseudo-obstruction on imaging: a case report.

Small bowel diverticulosis is a rare finding within the general population and jejunal diverticulosis, specifically, is even rarer. Clinical manifestations can range from post-prandial pain, constipation and malabsorption to serious complications, such as gastro-intestinal hemorrhage, perforation and acute intestinal obstruction. Here we describe the case of an 81-year-old gentleman who presented with a three-year history of abdominal pain and weight loss. Despite unremarkable physical examination and laboratory tests, persistent pneumoperitoneum and dilated loops of small bowel were found on imaging. Having been given a diagnosis of small bowel bacterial overgrowth, the patient underwent capsule endoscopy study for further evaluation of his small bowel. The capsule did not reach the colon and the patient never noted passing the capsule in his stool so, six months post-procedure, a computed tomography (CT) scan seemed to reveal the retained capsule. Subsequent exploratory laparotomy revealed 200 cm of atonic, dilated jejunum with impressive diverticula along the anti-mesenteric border. This case report is an example of an unusual set of presenting signs and symptoms of jejunal diverticulosis, including persistent pneumoperitoneum, pseudo-obstruction and small bowel bacterial overgrowth. A literature review has revealed that these signs have been present in other cases of jejunal diverticulosis, although the etiology and pathophysiology is not clearly understood.
