Traumatic intracranial aneurysms are rare lesions, accounting for less than 1% of all intracranial aneurysms. Formation of these lesions after a penetrating missile wound is very unusual, and diagnosis can be difficult due to the presence of associated lesions. In this article, we report a case of a woman who developed a middle cerebral artery aneurysm after a gunshot wound, and discuss potenti...

Spontaneous carotid-cavernous fistulae are uncommon. They are seen mostly in association with hypertension, atherosclerosis or intracranial aneurysm (Bickerstaff, 1970). Facial palsy was noted by Walsh (1957) in a case of traumatic carotid-cavernous fistula which recovered in one year. Involvement of the third, fourth, fifth and sixth cranial nerves has been frequently noted (Walsh, 1957; Sattl...

Large-vessel chronic traumatic arteriovenous fistulas are a rare complication after trauma. Delayed presentation can consist of one or more features of high-output cardiac failure, pulsatile abdominal mass, bruit, limb ischemia, and venous congestion. We describe a patient with a complex iliocaval fistula secondary to a remote gunshot wound associated with a large 8.5-cm aortic aneurysm. Inform...

Ultrasonography is a useful tool for the immediate evaluation of patients with suspected ruptured ectopic pregnancy, abdominal aortic aneurysm, traumatic intra-abdominal hemorrhage or cardiac tamponade. The 1999 Canadian Association of Emergency Physicians position statement states that bedside emergency department ultrasonography should be available 24 hours per day. This case study illustrate...

Background: Traumatic pseudoaneurysm of the supratrochlear artery is a rare lesion. It manifests, as a painless mass, in the frontal region following trauma. The unusual incidence and confusing presentation require the clinicians to thoroughly understand its presentation and diagnosis. Diagnosis is typically made on history and physical examination, but it can be confirmed by duplex ultraso...

BACKGROUND Traumatic intracranial aneurysms are rare conditions that can be a result of non-penetrating head trauma. We report the occurrence of intracranial aneurysms in patients with traumatic brain injury. METHODS All diagnostic cerebral angiograms performed in patients with traumatic brain injury at a level I trauma center from January 2006 to July 2007 were reviewed. RESULTS Diagnostic...

We report herein an 11-year-old pedestrian struck by a motorcycle, who suffered subdural hematoma and aortic rupture and developed traumatic pseudoaneurysm. He was treated conservatively for the first 24 hours and submitted to stent placement occluding the aneurysm neck. There were no recurrences in the post-procedure period and the child was discharged after 21 days without sequelae. This repo...

Pseudoaneurysm of the cavernosal artery is quite rare. Herein, we describe color Doppler findings of post-traumatic pseudoaneurysm of the right cavernosal artery in a 19-year-old adolescent boy who presented with right hip pain. Doppler showed turbulence of flow with arterial inflow and outflow from the aneurysm. Selective transarterial catheterization of the internal iliac and internal pudenta...

We report a 73-year-old woman with de novo arteriovenous malformations (AVMs) that developed in the ipsilateral parietal lobe after craniotomy and aneurysm clipping. While intracerebral AVMs are considered to be congenital lesions, there have been several reported cases of acquired AVM arising after ischemic or traumatic episodes. We summarize previously reported cases of such acquired 'de novo...
