Azygos and hemiazygos continuation: An occasional finding in emergency department.

Interruption of the inferior vena cava (IVC) with azygos continuation is a rare congenital anomaly, in which the IVC is interrupted below the hepatic vein and venous return beyond this point is restored by the dilated azygos and hemiazygos veins draining into the superior vena cava. A case of the interruption of the IVC with azygos/emyazygos continuation for the absence of the hepatic segment of IVC, left renal vein duplication, and polysplenia is reported. The embryologic, clinical, and radiological significance are discussed.

Stent-assisted coiling in ruptured cerebral aneurysms: multi-center experience in acute phase.

Introduction: The purpose of this study is to report on a multi-center experience of ruptured intracranial aneurysms treated in acute phase with stent-assisted coil embolization, including primary success rates and midterm follow-up results.

Materials And Methods: Retrospective analysis was performed on a sample of 40 patients (14 men, 26 women, mean age 59.7 years) affected by ruptured saccular aneurysms and treated by stent-assisted coiling in acute phase; double antiplatelet therapy with clopidogrel bisulphate and acetylsalicylic acid was started after the procedure.

Vertebroplasty Using Calcium Triglyceride Bone Cement (Kryptonite™) for Vertebral Compression Fractures. A Single-Centre Preliminary Study of Outcomes at One-Year Follow-up.

This study assessed the one-year clinical and radiographic outcomes, in terms of pain-relief, vertebral re-fracture and complications, after vertebroplasty (VP) using a new osteoconductive cement (calcium triglyceride bone cement - Kryptonite™ bone cement, Doctors Research Group Inc., Southbury, CT, USA) to treat osteoporotic vertebral compression fractures. Sixteen consecutive osteoporotic patients (12 women and four men, mean age 68+/-10.

Multisegmental diffuse intradural extramedullary ependymoma. An extremely rare case.

Ependymoma has been described typically as an intramedullary tumour derived from ependymal cells with a predominance in women in the fifth decade of life. Pain is the most frequent symptom. Intradural extramedullary presentation is rarely described and almost always as a unique lesion.

[Chordoma: diagnostic considerations and review of the literature].

Chordoma is a rare malignant tumor of the bone; it arises from embryonic remnants of the primitive notochord and occurs along the midline from the skull base to the sacrum. In this article, we reviewed the origin, location, clinical, histopatological and imaging features, treatment, and differential diagnosis of chordoma.
