CT of inferior vena cava filters: normal presentations and potential complications.

With massive pulmonary embolism (PE) being the first or second leading cause of unexpected death in adults, protection against PE is critical in appropriately selected patients. The use of inferior vena cava (IVC) filters has increased over the years, paralleling the increased detection of deep venous thrombosis (DVT) and PE by improved and more available imaging techniques. The use of IVC filters has become very common as an alternative and/or as a supplement to anticoagulation, and these filters are often seen on routine abdominal CT, including in the emergency setting; therefore, knowledge of the normal spectrum of findings of IVC filters by the radiologist on CT is critical.

CT of the skin and subcutaneous tissues.

A broad spectrum of skin and subcutaneous (SQ) findings may be discovered in the emergency setting on CT examinations. There are some findings that are directly relevant to the reason or reasons why the patient has undergone the CT examination. However, other findings may be incidental.

Imaging of abdominal pain in pregnancy.

This article reviews the evolving radiology and clinical literature on imaging of suspected common and relatively common maternal nonobstetric conditions of the abdomen and pelvis, including appendicitis, urolithiasis, and biliary disease, as well as on trauma to the maternal abdomen and pelvis and to the fetus. Recommendations for imaging these conditions, based on the literature to date and on the authors' experiences at two tertiary-care institutions with busy obstetric services, are proposed. The potential and theoretical fetal and maternal risks from such imaging are also reviewed.

Radiologic-pathologic findings of primary osseous adamantinoma with unusual metastasis to the posterior cul-de-sac in pregnancy.

Adamantinoma is a rare primary bone malignancy with a predilection for the tibial cortex. Metastases have been reported to the long bones, lung, pleura and spine. We present a 26-year-old pregnant woman with metastatic disease to the posterior cul-de-sac, lungs, liver and retroperitoneum, which collectively have not been previously reported in a single patient to our knowledge.
