The Application of Virtual Reality for Preoperative Planning of Lymphovenous Anastomosis in a Patient with a Complex Lymphatic Malformation.

The management of lymphatic malformations (LMs) is challenging, particularly for large and complex lesions involving anatomical structures in the adjacent tissue. While lymphovenous anastomosis (LVA) has been reported as an effective treatment for lymphedema, it has hardly been described as a treatment for LM. Virtual reality has the ability to visualize human structures in three dimensions and can be used for the preoperative planning of complex cases.

Lymphatic supermicrosurgery for the treatment of recurrent lymphocele and severe lymphorrhea.

Background: Lymphocele and lymphorrhea are frequent complications after lymph node excision. Recurrent lymphoceles and intractable lymphorrhea are particularly difficult to treat conservatively. We describe the outcomes of four patients with recurrent lymphocele and nine patients with persistent lymphorrhea that were treated by supermicrosurgery.

Positron emission tomography with FDG in the detection of peritoneal and retroperitoneal metastases of ovarian cancer.

Objective: The aim of this prospective study was to evaluate (18)F-FDG-PET, in comparison with CT, for the detection of peritoneal and retroperitoneal metastases of ovarian cancer.

Methodology: 13 patients with primary (n = 7) or recurrent (n = 6) ovarian cancer underwent an attenuation-corrected (18)F-FDG-PET of the abdomen as well as a contrast-enhanced abdominal CT, followed by surgical staging. For data analysis, the abdomen was artificially divided into six regions (right and left subphrenic region, right and left paracolic gutter, retroperitoneum and central abdomen).

18-FDG PET scan in the staging of recurrent melanoma: additional value and therapeutic impact.

Staging of melanoma patients by means of whole body functional imaging in a single evaluation session using positron emission tomography (PET) with fluorine-18- labelled deoxy-d-glucose (FDG) as a metabolic tracer has created much interest over the last decade. After enthusiastic pilot studies, more attention has been paid to the false-negative and false-positive results of this technique than to its true therapeutic impact. This study aimed to evaluate (1) the sensitivity and specificity of this technique at a single lesion level compared with conventional screening procedures (CSP) - both of these accompanied by careful clinical examination; and (2) the additional value of the PET scan at the level of the individual patient and its therapeutic impact for different types of melanoma recurrence.

Proliferative myositis in a child.

A case of proliferative myositis in the lumbar paraspinal muscles in a 14-year-old boy is presented. Imaging investigations including plain radiograph, ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), bone scan and positron emission tomography (PET) were suggestive of an inflammatory process such as myositis ossificans. The diagnosis was made by incisional biopsy.
