Spontaneous mediastinal hematoma is exceedingly rare. We described such a case of a 61-year-old male with a posterior mediastinal hematoma from ruptured small aneurysm, which was ascertained <em>via</em> contrast-enhanced computed tomography examination. Subsequent super-selective angiography of left gastric artery revealed a ruptured aneurysm with contrast medium leakage, feeding vessels respectively from caudal and cranial artery. The left gastric artery branch caudally feeding aneurysm was successfully occluded, while cranially feeding artery from the branch of left bronchial artery failed to embolize due to complex anatomic factor. Our management still yields to a satisfactory outcome.

AbstractA 7-year-old male patient with a history of recurrent abdominal pain over 1 year presented with cardiac tamponade due to massive pericardial effusion, which was percutaneously drained. Contrast-enhanced computed tomography revealed a large posterior mediastinal cyst and calcified, heterogeneous pancreatic parenchyma. Elevated amylase and lipase levels of the cyst fluid confirmed the diagnosis of pancreatic pseudocyst, which was treated with an octreotide infusion and Roux-en-Y cystojejunostomy. The child was discharged on pancreatic enzyme supplement and was asymptomatic on follow-up.

Purpose: To describe how the combined use of duplex and intravascular ultrasound (IVUS) can assist in the evaluation and treatment of isolated abdominal aortic dissection without need for contrast angiography. Case Report: A 78-year-old man presented with intermittent bilateral buttock and thigh claudication. Duplex ultrasound and contrast-enhanced computed tomography (CT) confirmed a chronic dissection along 3 to 4 cm of the infrarenal abdominal aorta. During Extra Large Palmaz stent implantation, the procedure was based on IVUS images and fluoroscopy without angiography. Both duplex and IVUS images were critical in assessing the type and extent of the lesion to be treated, in guiding the procedure, and in assessing its satisfactory outcome. Conclusions: In selected cases, ultrasound-based imaging modalities can provide most of the information required to accomplish complex aortic procedures.

Pulmonary Artery Pseudoaneurysm

Purpose: To report successful coil embolization of a rare traumatic pulmonary artery pseudoaneurysm. Case Report: A 57-year-old man developed a pulmonary artery pseudoaneurysm 14 days after he had been stabbed with a knife in the left lung. The pseudoaneurysm was diagnosed with contrast-enhanced computed tomography and confirmed by pulmonary arteriography. Coils were deployed in the feeding vessels to occlude the defect. Conclusions: Pulmonary artery pseudoaneurysm after penetrating chest injury can be treated by percutaneous catheter embolization, which is less invasive than surgery.

Cluster Of Differentiation

Epithelioid angiosarcoma arising in schwannoma is an extremely rare mesenchymal tumor that accounts for only 1 to 2% of all sarcomas. This type of tumor occurs in all parts of the body, most often in the skin and soft tissues and rarely in the mediastinum. The present study describes the case of an asymptomatic, 58-year-old male who presented with epithelioid angiosarcoma in the posterior mediastinum during a physical examination. Enhanced computed tomography of the chest revealed a 3.5 × 3.1-cm mass in the posterior mediastinum. Thoracoscopic mediastinal mass resection was performed under general anesthesia due to the possibility that the tumor was malignant. Pathological examination revealed the presence of angiosarcoma and schwannoma components. Immunohistochemical staining for cluster of differentiation (CD) 31, CD34, early growth response (EGR), vimentin, Sry-related HMG box (SOX)-10 and S-100 was strongly positive. The patient recovered and was discharged on postoperative day 5. Two months postsurgery, the patient returned for evaluation, and no evidence of tumor recurrence was observed.

This case report describes the chemoembolization of a small hepatocellular carcinoma employing a lipiodol drug delivery system utilizing a novel arterial pathway. Because the target lesion was precariously located adjacent to the inferior heart border and the diaphragm, it was unsuitable for imaging-guided microwave ablation. To achieve chemoembolization, several intraprocedural adaptations were necessary, given the variant anatomy encountered and difficulty accessing the left gastric artery through a celiac artery approach. The left gastric artery was selected from a superior mesenteric artery approach through the pancreaticoduodenal arcade (Rio Branco’s arcade). This case illustrates the importance of a mastery of the vascular anatomy and variants of hepatic arterial flow.
