Indications for CT in patients receiving anticoagulation after head trauma.

Background And Purpose: Head CT is frequently ordered for trauma patients who are receiving anticoagulation. However, whether patients with a Glasgow Coma Scale (GCS) score of 15 and normal findings on neurologic examination require CT is still debated. The purpose of our study was to assess the use of cranial CT in patients receiving anticoagulants after head trauma and to establish clinical criteria to identify those in this group who do not need emergency CT.

Ovarian torsion: CT findings in a child.

The computed tomography (CT) findings of ovarian torsion in a 10-year-old girl are presented. The CT scan was the first cross-sectional imaging examination performed in this patient, who presented with suspected acute appendicitis. Analogous to the sonographic diagnosis of ovarian torsion, the imaging findings may be pathognomonic on CT and should be prospectively recognized for prompt diagnosis.

Lower gastrointestinal bleeding from the internal iliac artery: angiographic demonstration of an iliac arteriocolic fistula.

A rare source of potentially massive lower gastrointestinal hemorrhage in women is advanced gynecologic malignancy. Such patients can develop gastrointestinal hemorrhage with or without prior pelvic irradiation, due to arteriocolic fistulas. Angiography permits the correct diagnosis and subsequent embolotherapy.

Juvenile granulosa cell tumor.

Juvenile granulosa cell tumor (GCT) of the ovary is a rare neoplasm occurring in premenarchal girls and young women. Juvenile GCT that occurs in premenarchal girls usually produces sexual precocity as a consequence of estrogen secretion. Juvenile GCTs are more likely to grow to a relatively large size with a much smaller likelihood of peritoneal spread, unlike their counterpart, epithelial ovarian neoplasms.

Combined CT venography and pulmonary angiography: a comprehensive review.

The combination of computed tomographic (CT) venography and pulmonary angiography (CTVPA) was initially described in 1998 as a single comprehensive noninvasive imaging examination for suspected thromboembolic disease. It allowed the identification of pulmonary embolism as well as deep venous thrombosis (DVT) in the abdomen, pelvis, thighs, and calves. The venographic portion of CTVPA has now been studied by multiple researchers and has been shown to be an accurate imaging study for the thigh veins in comparison with lower extremity sonography.
