CT imaging of complications of aortic intramural hematoma: a pictorial essay.

Aortic intramural hematoma (IMH) is a pathologic process with a clinical presentation identical to aortic dissection and associated with significant morbidity and mortality. Radiologists must be familiar with the imaging appearances of IMH as computed tomography (CT) plays a critical role in both diagnosis and patient management. The course of IMH is variable and the process may regress, remain stable, or progress in extent and therefore imaging findings associated with a negative prognosis must be recognized and included in the formal radiology report.

Radiographic Review of Current Therapeutic and Monitoring Devices in the Chest.

Chest radiographs are obtained as a standard part of clinical care. Rapid advancements in medical technology have resulted in a myriad of new medical devices, and familiarity with their imaging appearance is a critical yet increasingly difficult endeavor. Many modern thoracic medical devices are new renditions of old designs and are often smaller than older versions.

Hamartomas from head to toe: an imaging overview.

Hamartomas are tumours composed of mesenchymal tissues such as cartilage, fat, connective tissue and smooth muscle and can be found in virtually any organ system. These masses commonly develop sporadically, but are also seen in certain syndromes such as tuberous sclerosis or Carney triad. While their imaging appearance varies depending on the organ they arise from, findings are usually unique and a diagnosis can be confidently made.

Cystic Lesions of the Mediastinum.

Cystic lesions are commonly seen in the mediastinum, and they may arise from virtually any organ. The vast majority of these lesions are benign and result in no symptoms. When large, cysts may produce symptoms related to compression of adjacent structures.

Fatty lesions in and around the heart: a pictorial review.

A wide variety of fat-containing entities occur in and near the heart. These findings are often encountered by radiologists and may be incidental or the reason for the patient's clinical presentation. Cross-sectional imaging helps to characterize the extent of these lesions and to formulate a differential diagnosis, which varies by lesion location, imaging features and patient demographics.

Computed tomography of acute heart failure: A novel case and literature review.

Computed tomography (CT) is used in patients whose conditions span the gamut from healthy to critically ill. In the specific subset of patients with cardiac arrest or imminent cardiac failure who receive contrast-enhanced CT, extant literature illustrates a set of imaging findings that include inferior vena cava and hepatic parenchymal contrast reflux, pooling, and layering in a dependent fashion. We review the literature and present a case in which these findings are demonstrated along with renal venointerstitial reflux, a finding that has not been previously described.

Renal epithelioid angiomyolipoma with a negative premelanosome marker immunoprofile: a case report and review of the literature.

Introduction: The rare variant of renal epithelioid/pleomorphic angiomyolipoma has been reported in approximately 120 cases. One of the most important characteristics to differentiate these tumors from other renal cell neoplasms is their typical reactivity to premelanosome antigens. If such a tumor does not stain for HMB-45 or Melan-A, a specific diagnosis of epithelioid pleomorphic angiomyolipoma cannot be made with certainty.

Transvaginal ultrasonographic findings in surgically verified ectopic pregnancy.

Objective: Our purpose was to evaluate transvaginal ultrasonographic findings in ectopic pregnancies for positive ultrasonographic sign(s).

Study Design: Eighty-nine patients admitted with an ectopic pregnancy from September 1987 through September 1989 were retrospectively reviewed. Sixty-nine had undergone transvaginal ultrasonography within 10 days before surgery.

Biopsy proven eradication of an aneurysmal bone cyst treated by superselective embolization: a case report.

A large aneurysmal bone cyst of the upper tibia in a 17-year-old patient was treated by superselective embolization with excellent clinical and radiological results. Extensive curettage and detailed pathologic analysis performed 2 years following embolization revealed only healing bone. The presented case and reviewed cases in the literature indicate that embolization is a promising method for definitive therapy of the aneurysmal bone cyst.
