Abdominal pelvic CT findings compared between COVID-19 positive and COVID-19 negative patients in the emergency department setting.

Purpose: Manifestations of COVID-19 are primarily respiratory based, however, gastrointestinal symptoms are now recognized as an important component of the disease. The purpose of this study is to evaluate differences in abdominal pelvic CT findings in the emergency department by COVID-19 test result.

Methods: This retrospective study identified patients tested by PCR for COVID-19 infection who underwent abdominal pelvic CT scan in the ED across an academic health system from March 15 to April 15, 2020.

Role of CT in the management of recurrent ovarian cancer.

Objective: The purpose of this study was to evaluate the potential role of preoperative CT in patients with recurrent ovarian cancer who undergo secondary cytoreductive surgery.

Materials And Methods: Preoperative CT examinations of 36 consecutive patients (age range, 30-75 years; mean age, 55 years) were reviewed retrospectively. Patients had recurrent ovarian cancer and secondary cytoreduction within a mean CT-surgery interval of 22 days (range, 2-69 days).

Ovarian malignancies.

Ovarian cancer is the second most common pelvic tumor and the leading cause of death from a gynecologic malignancy. MRI plays a strategic role in patient care for initial evaluation and treatment planning in patients with ovarian cancer. This article reviews the pathologic classification and characteristic findings on MRI of ovarian malignancies, patterns of tumor spread and staging, and the utility of cross-sectional imaging prior to primary and secondary to cytoreproductive surgery.

Utility of sonography for small hepatic lesions found on computed tomography in patients with cancer.

Objective: To assess the performance of sonography in evaluating small indeterminate liver lesions detected on computed tomography in patients with cancer.

Methods: Radiology database review from January 1, 1998, to August 4, 2000, identified 76 patients with 124 indeterminate hepatic lesions smaller than 1.5 cm on computed tomography who had abdominal sonography within 3 months.

Subcutaneous nodules at the injection site of low-molecular-weight heparin: a mimic of metastatic disease at CT.

Purpose: To describe the appearance and prevalence of subcutaneous nodules in the anterior abdominal wall seen at CT in cancer patients receiving subcutaneous injections of low-molecular-weight heparin (LMWH).

Methods: CT examinations were reviewed in 426 patients receiving subcutaneous abdominal wall injections of LMWH for the presence of nodules. Nodules were evaluated for contour, maximal diameter, CT attenuation, and presence of hazy changes or air in the surrounding fat.

Detection and characterization of adnexal masses.

The main challenge to the radiologist is to differentiate benign from malignant adnexal masses. Both US and MRI perform well for prediction of benignity. There is less specificity for diagnosis of malignancy but features, such as papillary projections, thickened septations, and internal vascularity within nodules, aid in this differentiation.
