Pulmonary artery sarcoma (PAS) is a rare and fatal disease. PAS can often be misdiagnosed as pulmonary thromboembolism. Moreover, the correct diagnosis is frequently delayed due to nonspecific signs and symptoms. The prognosis of patients with PAS is poor. We report a case of a woman with a primary PAS who was initially diagnosed with pulmonary thromboembolism.

PURPOSE: This study aims to compare image quality, radiation dose, and the influence of the heart rate on image quality of high-pitch spiral coronary computed tomography angiography (CCTA) using 128-slice (second generation) dual-source CT (DSCT) and a 192-slice DSCT (third generation) scanner. MATERIALS AND METHODS: Two consecutive cohorts of fifty patients underwent CCTA by high-pitch spiral scan mode using 128 or 192-slice DSCT. The 192-slice DSCT system has a more powerful roentgen tube (2 × 120 kW) that allows CCTA acquisition at lower tube voltages, wider longitudinal coverage for faster table speed (732 m/s), and the use of iterative reconstruction...

We present a case of a geriatric male with giant ascending aortic aneurysm (AAA) who underwent successful coronary angiography using telescoping technique for evaluation his coronary arteries before surgery for AAA. Since the ascending aorta and root were extremely dilated, we knew it would not have been possible to engage the coronaries using regular catheters and standard technique. Hence, telescopic technique was used. Amplatz left 3 (AL3) 7F (French) guide catheter (90 cm) was initially used, and nonselective injection of contrast was done to see the coronary ostium...

Septic thrombophlebitis of the portal vein and/or its intra-hepatic branches (pylephlebitis) with associated liver abscess formation is a rare and potentially fatal complication of intra-abdominal infection. We present such a case that was caused by missed chronic appendicitis. Imaging findings can be complex and mimic other diseases leading to a diagnostic conundrum. Radiologists need to be knowledgeable of this challenging condition to prevent misdiagnosis and because prompt treatment is often life-saving...

Percutaneous microwave coagulation therapy has been one of the major new developments in tumor ablation. Microwave ablation has also been used intraoperatively to achieve hemostasis at surgical margins in laparotomy. However, the use of microwave ablation for coagulation and hemostasis through percutaneous approach has not been described in the literature. Here, we report a case of hepatic amyloidosis with massive post biopsy liver hemorrhage, which could not be by transarterial embolization, and subsequently controlled by ultrasound-guided percutaneous microwave ablation...

Metastatic tumors are rare in the breast. Well-differentiated neuroendocrine tumors (WDNETs) are slow-growing neoplasms that arise from neuroendocrine cells, particularly in the gastrointestinal tract and bronchial tree. Metastatic WDNET to the breast is a rare entity. We present a case report of ileal WDNET metastatic to the breast which was initially identified as a small mass in the patient's left breast on screening mammography. Targeted ultrasound identified a suspicious mass, and ultrasound-guided percutaneous core biopsy was performed...

Extramedullary plasmacytoma is rare in patients with diagnosed multiple myeloma. Soft tissue plasmacytoma of the gallbladder is particularly uncommon and has been described in only a handful of cases. Diagnosis of gallbladder plasmacytoma with fluorine 18-fluorodeoxyglucose (F18-FDG) positron emission tomography/computed tomography (PET/CT) has not previously been reported. We present a 65-year-old female with a history of multiple myeloma who underwent a restaging F18-FDG-PET/CT which showed a focal area of hypermetabolic activity, corresponding to a nodular lesion within the posterior gallbladder wall...

Despite progress in noninvasive imaging with computed tomography and magnetic resonance imaging, conventional angiography still contributes to the diagnostic workup of oncologic and other diseases. Arteriography can reveal tumors not evident on cross-sectional imaging, in addition to defining aberrant or unexpected arterial supply to targeted lesions. This additional and potentially unanticipated information can alter management decisions during interventional procedures.

Fibrosing mediastinitis is a rare condition defined by the presence of fibrotic mediastinal infiltrates that obliterate normal fat planes. It is a late complication of a previous granulomatous infection, such as histoplasmosis or tuberculosis (TB). Due to its rarity, fibrosing mediastinitis is often under-recognized, and the clinical presentation is variable and dependent on the extent of infiltration or encasement of structures within the mediastinum. We present a case of fibrosing mediastinitis in a man with a prior history of TB, who presented with progressive dyspnea and was found to have chronic mediastinal soft tissue opacities and pulmonary hypertension...

We present a case of a 69-year-old patient who underwent ascending aortic aneurysm repair with aortic valve replacement. On postsurgical day 12, he developed leukocytosis and low-grade fevers. The chest computed tomography (CT) showed a periaortic hematoma which represents a postsurgical change from aortic aneurysm repair, and a small pericardial effusion. The abdominal ultrasound showed cholelithiasis without any sign of cholecystitis. Finally, a fluorodeoxyglucose (FDG)-positron emission tomography (PET)/CT examination was ordered to find the cause of fever of unknown origin, and it showed increased FDG uptake in the gallbladder wall, with no uptake in the lumen...

Patients with locally advanced gastroesophageal cancers frequently undergo concurrent chemotherapy and radiation (CRT). 18-fluorodeoxyglucose-positron emission tomography ((18)FDG-PET) in combination with computed tomography is used for disease staging and assessing response to therapy. (18)FDG-PET interpretation is subject to confounding influences including infectious/inflammatory conditions, serum glucose, and concurrent medications. Radiotherapy induces tissue damage, which may be associated with FDG-avidity; however, few reports have described the focal areas of hepatic uptake following concurrent chemoradiation (CRT)...

Dual-energy computed tomography (DECT) simultaneously acquires images at two X-ray energy levels, at both high- and low-peak voltages (kVp). The material attenuation difference obtained from the two X-ray energies can be processed by software to analyze material decomposition and to create additional image datasets, namely, virtual noncontrast, virtual contrast also known as iodine overlay, and bone/calcium subtraction images. DECT has a vast array of clinical applications in imaging cerebrovascular diseases, which includes: (1) Identification of active extravasation of iodinated contrast in various types of intracranial hemorrhage; (2) differentiation between hemorrhagic transformation and iodine staining in acute ischemic stroke following diagnostic and/or therapeutic catheter angiography; (3) identification of culprit lesions in intra-axial hemorrhage; (4) calcium subtraction from atheromatous plaque for the assessment of plaque morphology and improved quantification of luminal stenosis; (5) bone subtraction to improve the depiction of vascular anatomy with more clarity, especially at the skull base; (6) metal artifact reduction utilizing virtual monoenergetic reconstructions for improved luminal assessment postaneurysm coiling or clipping...

A complete hydatidiform mole with a viable coexisting fetus (CMCF) is a rare occurrence. Similarly, Mullerian anomalies such as a bicornuate uterus are uncommon variants of normal anatomy. We report a case of a 40-year-old female with a known bicornuate uterus presenting at 13 weeks gestation with vaginal bleeding. Ultrasound findings showed a healthy viable pregnancy in the right horn with complete molar pregnancy in the left horn. After extensive counseling, the patient desired conservative management, however, was unable to continue due to profuse vaginal bleeding...
