A 52-year-old woman presented with bilateral distal anterior cerebral artery (ACA) mirror aneurysms, in addition to two right middle cerebral artery (MCA) aneurysms. The left distal ACA and right MCA aneurysms were clipped through right interhemispheric and right pterional craniotomies. The right distal ACA aneurysm was thrombosed. Distal ACA aneurysms tend to be multiple, but mirror aneurysms ...

A 39-year old gentleman presented with cough and haemoptysis for 5 years. A chest radiograph showed a large left retrocardiac opacity (Fig. 1). A contrast enhanced computerised tomography of the thorax showed a hypertrophied aberrant systemic artery from the descending thoracic aorta, leading to a large saccular, partially thrombosed aneurysm in the left lower lobe (Fig. 2). The patient underwe...

We report a case of a giant serpentine aneurysm (GSA) of the middle cerebral artery (MCA) that underwent complete spontaneous thrombosis after angiography. The patient was a 24-year-old man who had an acute headache. CT and MR examinations revealed a large partially thrombosed aneurysm of the MCA with residual flow in the artery. Angiography demonstrated a GSA arising from the left MCA. Thirtee...

A 57-year-old man, who was a chronic axillary crutch user as a result of childhood poliomyelitis, was referred to our hospital because of a sudden onset of right forearm ischemia. The right forearm had no pulse, and three-dimensional computed tomography (3DCT) showed an aneurysm of the right brachial artery associated with arterial occlusion. The thrombosed aneurysm of the brachial artery was r...

The mechanisms of thrombus formation in atherosclerotic cerebral arteries are still controversial, although intraplaque haemorrhage and rupture of the atheromatous plaques have been proposed. A histopathological analysis of segments of the thrombosed large intracranial arteries was carried out on eight patients who died within 28 days after brain infarction. The study revealed occlusive thrombi...

The management of severely hypoplastic pulmonary arteries in the adolescent or adult with congenital heart disease is challenging. A patient with pulmonary atresia and ventricular septal defect (PA-VSD) presented with severe cyanosis due to a kinked and thrombosed right ventricle to pulmonary artery conduit. Retrograde wedge angiography showed a patent right and a diminutive left pulmonary arte...

Twelve patients in a series of 22 with giant intracranial aneurysms demonstrated neuroradiological features of partial or total spontaneous intra-aneurysmal thrombosis. The presence of this intra-aneurysmal clot significantly altered the computed tomographic appearance of the giant aneurysm. Massive intra-aneurysmal thrombosis did not protect against subarachnoid haemorrhage and the likelihood ...

We report a case of a 36-year-old male who presented with a pulsatile mass at the left temporal region after a head injury. Duplex sonographic examination confirmed the diagnosis of traumatic pseudoaneurysm of the superficial temporal artery. Imaging showed the pseudoaneurysm was partially thrombosed.

The term mycotic aneurysm involves an infection of secondary aneurysmal wall to bacterial endocarditis. The 63% of mycotic aneurysms of the superior mesenteric artery are due to embolism from a septic endocarditis. Although most of these aneurysms is diagnosed, due to the increase in diagnostic methods, even a quarter of the superior mesenteric artery aneurysms present with rupture, intestinal ...
