Metastatic Pheochromocytoma of the Thoracic Spinal Extradural Space : Case Report and Review of the Literature

In this case report, a thoracic extradural metastatic pheochromocytoma withoutbony invasion, is presented. The disease which has been identified with it's symptoms,bio-chemical features, radiological appearance, histological diagnosis has beendiscussed in comparison with malignant pheochromocytoma metastases in theliterature. The origin of this tumor is the adrenal glands. Our review of the literatureshows that tumor has primary metastasis in bony structures of the spine and thendemonstrates secondary intraspinal invasion. This is the first case report of an epiduralmetastasis from malignant pheochromocytoma without a bony invasion

A large primary dumbbell hydatid cyst causing neural foraminal widening of the thoracic spine: A case report and literature review

Introduction: Spinal hydatid cyst is a rare, but serious condition. Presentation of the case: Herein, we present a 17-year-old male patient with back pain radiating to the legs and progressive weakness in the lower limbs. CT and MRI showed a spinal-paraspinal hydatid cyst with a dumbbell appearance that caused neural foraminal widening and spinal cord compression. The case was explored via right T3-T4 hemilaminectomy, and the hydatid cyst was completely removed. Discussion: The clinical presentation, diagnosis, and surgical treatment of this rare case of spinal hydatid disease are discussed, and all published cases of primary dumbbell hydatid cyst are reviewed. Conclusion: Even if serological test results are negative, hydatid cysts should be considered in the differential diagnosis of cystic lesions of the spine

Ruptured distal anterior choroidal artery aneurysm

WOS: 000262348500031PubMed ID: 19013815This report describes a patient with a rare distal anterior choroidal artery (AChoA) aneurysm that developed a right intracerebral haematoma and intraventricular haemorrhage and was treated by surgical exploration and clipping via a transtemporal/ventricular approach. The patient was discharged neurologically intact. We review the literature related to these rare aneurysms within the temporal horn, and the surgical anatomy of the AChoA.

Ruptured distal middle cerebral artery aneurysm: Case report

INTRODUCTION This report describes a rare case of a distal middle cerebral artery (dMCA) aneurysm. PRESENTATION OF CASE That developed a right intracerebral haematoma and subarachnoid haemorrhage. It was treated by surgical exploration and clipping via pterional approach. DISCUSSION Clinical findings and surgical approaches of dMCA aneurysm are different from proximal middle cerebral artery (MCA) aneurysms. Microneurosurgical clipping is the most effective treatment of dMCA aneurysm. CONCLUSION We comprehensively review the literature related to these rare aneurysms within the temporal lobe, surgical anatomy of the dMCA aneurysm. © 2013 The Authors

Giant Fusiform Basilar Artery Aneurysm Causing Obstructive Hydrocephalus

A 58-year-old man presented with a sudden onset gait disturbance and urinary incontinence. Magnetic resonance (MR) imaging and MR angiography showed a fusiform basilar artery aneurysm, 2 cm in diameter and 5 cm long. The aneurysm was thrombosed except the ectatic basilar artery flowing through it. Compression of the cerebrospinal fluid (CSF) pathways caused obstructive hydrocephalus with resultant transependymal CSF leakage. Conventional angiography missed the aneurysm. A one-sided ventriculoperitoneal shunt was placed to treat the patient's hydrocephalus. The patient's symptoms improved after surgery. MR imaging and MR angiography were useful noninvasive methods of detecting the aneurysm, defining its relationship with surrounding structures, and determining the cause of the hydrocephalus

A Rare Embryologic Variation: Anterior Communicating Artery Aneurysm Associated with Carotid–-Anterior Cerebral Artery Anastomosis or Infraoptic Course of the Anterior Cerebral Artery

Aneurysms of the complex of the anterior cerebral artery are frequently associated with anatomic variations of the circle of Willis. We describe a case of aneurysmal rupture of the anterior communicating artery, a variant of the anterior cerebral artery. The aneurysm appeared to be situated on this vessel proximal to the infered site of the AcoA. Surgery was performed at the 6th day after hemorrhage. The anterior communicating artery aneurysm was clipped. The post operative course was unventful, with complete recovery. In our case, an extremely rare variation of the proximal tract of the anterior cerebral artery, i.e. an infraoptic course of the proximal precommunicating tract under the optic nerve, with the distal A1 tract anterior to the chiasm and positioned between the optic nerves, is presented

Treatment of aneurysms arising from the proximal (A1) segment of the anterior cerebral artery

The aim of our study was to report a series of 15 consecutive patients with aneurysms of the proximal segment (A1) of the anterior cerebral artery. In 15 patients with diagnosed A1 aneurysms, representing 2.1% of 720 aneurysm patients treated at a University Clinical Center between October 1999 and August 2012, clinical presentation, neuroradiological findings, surgical treatment methods and outcome were retrospectively analyzed. Mean patient age was 53.06 (range 32 to 75) years. Ten saccular aneurysms were treated with micro neurosurgical approach via standard pterional craniotomy, four fusiform aneurysms with coiling, and one fusiform aneurysm with stent. No patients died during the operation. The mean follow-up period was 32 months (range 5 months to 7 years). Clinical outcomes revealed good recovery in all patients. Despite the general opinion that A1 aneurysms are benign lesions, an increasing number of reports have demonstrated their potential complications. To date, due to the rarity of A1 aneurysms, only a few consecutive series have been reported. Conduct of multicenter studies are required in order to understand clinical features of A1 aneurysms and devise a proper treatment plan
