The complex embryology of the anterior mediastinum makes it home to an array of primary neoplasms tied to the presence of the thyroid and thymus glands in that compartment. While the occurrence of ectopic thyroid deposits in the extramediastinal thorax has not been convincingly established, the other three "Ts" of the classic "4T" mnemonic for the differential diagnosis of an anterior mediastinal mass have occurred in the lung parenchyma, pleural space, and endobronchially as primary tumors. Finding any of the three lesions - thymoma, teratoma, or B-cell lymphoma - in the chest outside the mediastinum is very unusual, but that possibility exists...

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.

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.
