Computed tomography-guided navigated transcranial magnetic stimulation for preoperative brain motor mapping in brain lesion resection: A case report.

Background: Navigated transcranial magnetic stimulation (nTMS) is a well establish a noninvasive method for preoperative brain motor mapping. We commonly use magnetic resonance imaging (MRI) to supply the nTMS system. In some cases, MRI is not possible or available, and the use of computed tomography (CT) is necessary.

Microsurgical Treatment of Intraventricular Cavernoma with Prior Planning Neuroendoscopy.

Microsurgery remains the gold standard treatment for intraventricular lesions, but it is not without limitations. The cerebral ventricles approach is considered a challenge for neurosurgeons because of their deep location and their intimate association with critical areas of the brain. It has been shown that direct endoscopic view is superior to magnetic resonance imaging (MRI) in identifying intraventricular structures and lesions.

Solid pseudopapillary tumor of the pancreatic: evaluation of clinical, radiological and surgical profiles.

Objective: To describe the clinical, radiological and surgical features of solid pseudopapillary tumor of the pancreas.

Methods: We conducted a retrospective, observational study evaluating the multi-institutional clinical, radiological and surgical patients with a diagnosis of solid pseudopapillary tumor of the pancreas undergoing surgical treatment.

Results: We identified eight patients in three hospitals in the state of Amazonas, seven females, six under the age of 30.
