Percutaneous vertebroplasty of the C2 body and dens using the anterior oblique ascending transdiscal approach.

This first description of percutaneous vertebroplasty (PVP) of the second cervical vertebra (C2) using an ascending oblique transdiscal approach is a case report of a 63-year-old woman who complained of neck pain that was resistant to painkillers and the result of an osteolytic metastatic lesion of C2. PVP was performed using an ascending oblique transdiscal approach, a percutaneous technique that had never been described before. It has since been used in more than 15 patients, resulting in pain relief and stabilization of C2 with good distribution of cement across the vertebral body and dens. Also, there were no complications and no leakage of cement along the path of the needle.

[Congenital mesoblastic nephroma: diagnosis and treatment of one case]. / Le néphrome mésoblastique congénital : diagnostic et prise en charge à partir d'un cas.

The congenital mesoblastic nephroma (CMN) described by Bolande et al. in 1967 is a renal tumor often discovered in neonatal period and early childhood. It's usually considered as a benign tumor with good prognostic for which nephrectomy is the reference treatment. But some cases of local recidives and metastatic sites had been described in the literature. For these reasons histologic analysis and quality of follow up are very important. In this observation we describe a neonatal kind of CMN and we discuss this pathology.

[Hepatic Epithelioid hemangioendothelioma: a rare liver tumor]. / L'hémangioendothéliome épithélioïde du foie: une tumeur hépatique rare.

Epithelioid hemangioendothelioma of the liver is a rare primary malignant tumor of vascular origin. It most frequently occurs in middle age adults and clinical findings are non-specific. Histological diagnosis may be difficult to achieve with lesions containing a large myxoid component, and immunohistochemical staining is required. A few imaging features may suggest the correct diagnosis, and radiologists should be familiar with these findings. We will illustrate the potential role of PET-CT at the time of initial presentation. Prognosis is variable and optimal management is based on a case by case analysis, ranging from clinical and imaging follow-up to liver transplantation.
