Single-Session Surgical Intervention with Resection of a Primary Cranial Osteosarcoma and Cranioplasty using a 3D-Printed Craniotomy Template and Cranioplasty Molds.

Although osteosarcomas are the most frequent primary malignant bone tumors, the primary cranial manifestation of this condition is very rare with only a limited number of cases presented in the literature. We present the case of a 20-year-old male patient who underwent single-session surgical intervention for resection of right frontal osteosarcoma with a tailor-made craniotomy and cranioplasty using virtually designed 3D-printed templates and molds. Subsequently, the patient was treated according to the EURAMOS protocol and received adjuvant systemic chemotherapy.

The Manufacturing of 3D Printed models for the Neurotraumatological Education of Military Surgeons.

Introduction: When deployed abroad, military surgeons frequently have to deal with casualties involving head trauma. The emergency treatments, as well as craniotomies, are often performed by non-neurosurgeons qualified with basic neurotraumatological skills. Previous neurotrauma courses for education of non-neurosurgeons in Germany teach surgical emergency skills but do not include the training of skills needed to successfully utilize imaging in surgical planning, which is of importance for the safety and success of the treatment.

ioCT-guided percutaneous radiofrequency ablation for trigeminal neuralgia: how I do it.

Background: Percutaneous trigeminal nerve rhizotomy is usually performed by free-handed puncture of the foramen ovale under radiographic control with the patient kept semiconscious. The procedure has thus been reported to be highly uncomfortable for both the patient and surgeon. To our knowledge, this is the first description of a technique that includes precise navigated, CT-guided puncture of the foramen with the patient in general anesthesia and confirmation of needle placement by intraoperative CT.

Hypertrophic pachymeningoencephalitis associated with temporal giant cell arteritis.

We report the rare case of an 80-year-old male patient with hypertrophic pachymeningoencephalitis that may be associated with temporal arteritis. The patient presented to our neurological department with a 2-week history of latent paresis and ataxia affecting his right hand. He had been diagnosed with temporal arteritis 12 years earlier.

Assessment of rhabdoid brain tumor by F-18 FDG PET, C-11 methionine PET and MRI.

A 28-year-old man with headache, nausea, and decreased vision had a left parieto-occipital tumor demonstrated by MRI. Postradical resection and histology showed a solid mass containing rhabdoid cells, 10% positive for Ki-67. After completing chemotherapy and radiotherapy treatment, follow-up MRI revealed possible tumoral recurrence.

Use of twist-drill craniostomy with drain in evacuation of chronic subdural hematomas: independent predictors of recurrence.

Background: Recurrence rates after chronic subdural hematoma (CSDH) evacuation with any of actual techniques [twist-drill craniostomy (TDC), burr-hole craniostomy, craniotomy] range from 5% to 30%. Use of drain has improved recurrence rates when used with burr-hole craniostomy. Now, we analyze predictors of recurrence of TDC with drain.
