A 47-year-old man experienced recurrent pulmonary embolism resistant to aggressive medical and surgical prophylaxis. Although paraneoplastic hypercoagulability was suspected, no endoscopic or radiologic signs of malignancy were detected. Death was the result of electromechanical dissociation, which was attributed to right ventricular outflow obstruction. At autopsy, anaplastic lung carcinoma wa...

specified medical condition(s). These criteria are intended to guide radiologists and referring physicians in making decisions regarding radiologic imaging and treatment. Generally, the complexity and severity of a patient’s clinical condition should dictate the selection of appropriate imaging procedures or treatments. Only those exams generally used for evaluation of the patient’s condition a...

The differential diagnosis of pulmonary cavitation is broad. The most common causes include infection and malignancy. Pulmonary thromboembolism is a common problem worldwide, with an estimated 650,000 cases in the United States annually. Pulmonary embolism does not usually lead to cavitation, given the dual blood supply of the lung; however, cavitation may complicate 4–7% of all pulmonary infar...

The advent of sophisticated and sensitive radiologic techniques has undoubtedly improved the evaluation of patients with established endocrine disease. An inevitable consequence of the increased sensitivity and widespread availability of modern imaging is, however, the discovery of apparently asymptomatic mass lesions in endocrine tissues. The clinician is then required to determine the appropr...

Hand and wrist radiographic indexes such as radial inclination, ulnar variance, carpal height ratio, and radial tilt play an important role in the diagnosis and management of medical disorders, so they should be modified regarding the population and race difference. This study aims to compare the normal radiologic wrist indexes in Mashhad population with other existing databases and define some...

The diagnostic evaluation of a patient with reversible cerebral vasoconstriction syndrome integrates clinical, laboratory, and radiologic findings. Imaging plays an important role by confirming the presence of cerebral vasoconstriction; monitoring potential complications such as ischemic stroke; and suggesting alternative diagnoses, including CNS vasculitis and aneurysmal subarachnoid hemorrhag...

PURPOSE To review the diagnostic examination and clinical presentation of mucinous cystadenoma of the appendix. METHODS Case report from experience at an Air Force tertiary care hospital in a 66-year-old woman with chronic right lower quadrant pain. RESULTS After extensive preoperative evaluation and subsequent diagnostic laparoscopy, a right hemicolectomy was performed for a mucinous cysta...

A woman was referred to our hospital with the working diagnosis of ovarian malignancy. While she was undergoing both clinical and radiological evaluation and monitoring, a decrease in the size of the ovarian mass was noted. After further evaluation via laboratory findings and tissue biopsy, we arrived at a final diagnosis of sarcoidosis, which is very unusual in the ovaries. Our case places emp...
