vertebral artery pseudoaneurysm, is the subject of this report. The size and location of this aneurysm led to the choice of endovascular occlusion of the vertebral artery proximal to the aneurysm neck, which resulted in an excellent recovery. The interrelationship between neurofibromatosis, arterial lesions, and trauma is discussed in this case report. Case Report This 52-year-old Caucasian woman was admitted for evaluation of a painful enlarging mass on the left side of her neck. Two weeks previously she had undergone an elective abdominal hysterectomy and on the 1

vertebroplasty. 2 , 4 In this article, we describe the development of pseudoaneurysm and direct focal aortic dissection as a complication in PV, and we discuss the optimal technique to avoid this complication. Both patients had undergone recent PV via a transpedicular approach at another institution and were subsequently referred to our institution for treatment based on their symptoms and imaging findings. Case Reports Case 1 History and Examination This 67-year-old woman was transferred from another hospital due to the diagnosis of a left lumbar artery

I atrogenic vascular injury after lumbar spinal surgery is rare. 1 , 5 , 8 Arterial structures that may be damaged include the aorta and the iliac and lumbar arteries. Vascular damage can present with acute or delayed symptoms. Laceration of a major vessel may cause a massive retroperitoneal hemorrhage requiring immediate surgical or endovascular repair. 3 , 5 , 7 , 8 Delayed onset of chronic symptoms or signs may occur when an arteriovenous fistula or pseudoaneurysm is formed. 2 , 4–6 , 8 , 9 We present our experience in the treatment of a patient

F emoral nerve palsy caused by iliacus hematoma is a rare entity most often occurring in individuals receiving anticoagulation therapy, patients with blood dyscrasias such as hemophilia, and patients in whom an anterior iliac crest graft has been harvested. 7 Fewer cases have been reported following trauma, and most of these were in teenage patients following hyperextension injuries to the hip. 2–5, 9, 11, 13–17 Our case illustrates an unusual source of this type of injury, a traumatic pseudoaneurysm. The management and timing of interventions in this injury

O ccasional cases of cerebrovascular moyamoya disease associated with an intracranial aneurysm have been reported. The aneurysms have been described as saccular, fusiform, or pseudoaneurysms. 1, 3–5, 7, 8, 10, 11 To our knowledge, this is the first report of a pseudoaneurysm verified histologically in a patient with moyamoya disease. Case Report This previously healthy 51-year-old woman experienced a sudden attack of headache on July 11, 1979. Nineteen hours later, while working as a caddie, she became unconscious. She was taken to another hospital

C omplications following the placement of CSF shunts are protean and include common problems such as obstruction and infection 4 and uncommon problems such as premature suture closure, 12 seizures, 20 metastases, 6 and visual loss. 9 To our knowledge, the formation of a pseudoaneurysm after the placement of a ventricular shunt catheter as part of a CSF diversion procedure has not been reported previously. We report a case in which the placement of a ventricular catheter as part of a VP shunt via a coronal approach may have resulted in the formation of

A lthough pseudoaneurysms are rare, accounting for < 1% of all intracranial aneurysms, they are associated with significant morbidity and mortality rates. 1 , 6 , 10 , 17 , 20 Intracranial hemorrhage ensues in up to 60% of patients with subsequent mortality rates ranging from 31–54%. 12 , 17 , 20 Pseudoaneurysms occur as a consequence of a multitude of preceding events, including traumatic, infectious, and iatrogenic causes, and they are more frequent in the pediatric population. 1 , 2 , 7 , 9–11 , 13 , 16 , 18 , 19 Furthermore, they pose a significant

A lthough patients with an aneurysm generally present with cerebral SAH, spinal cord SAH is very rare. Spinal SAH is caused by AVM, aneurysm, or tumor. 1, 2, 6, 9, 12, 13 Most spinal SAHs are thought to occur when a spinal AVM and aneurysm coexist. 1–3, 6, 9 We describe a rare case of spinal pseudoaneurysm that developed into SAH and document findings indicating that the pseudoaneurysm was the likely cause of the SAH. Case Report History This 71-year-old woman was hospitalized to undergo medical treatment of autoimmune hepatitis. She underwent

A neurysms or pseudoaneurysms of the spinal vasculature are a rare cause of SAH. Spinal SAH is primarily a result of high-flow vascular lesions such as arteriovenous malformations, 2 dural arteriovenous fistulas, and associated aneurysms. Isolated PSA aneurysms (that is, with no associated high-flow state) are rare, and to date only 8 cases have been reported. 1 , 3 , 6–11 We report a case of a ruptured isolated PSA pseudoaneurysm at the thoracic level presenting with SAH, which was subsequently treated with endovascular obliteration. We also discuss the

regions; the studies demonstrated the development of a pseudoaneurysm off the posterior wall of the aorta adjacent to the T-11 fracture ( Fig. 2 left ) and a fistula leading toward the site of the spinal fracture. An emergency angiographic study was ordered, and two vascular stents were placed to occlude the defect ( Fig. 2 right ). This procedure was performed without complication, and the patient was then transferred to the intensive care unit. Fig. 2. Left: Reconstructed CT scan revealing the aortic lesion.
