Case Reports
Intracranial infantile myofibromatosis mimicking malignant brain tumor: A case report and literature review.
Myofibroma is a fibrous tumor of infancy that sometimes affects a single patient in a multiple fashion (infantile myofibromatosis). Its intracranial involvement is extremely rare, and its clinical picture has been poorly characterized. Here we report an interesting case of myofibromatosis with an intracranial lesion that behaved like an aggressive tumor and yet demonstrated very benign pathology. ⋯ The discrepancy between rapid tumor growth associated with increased uptake on metabolic imaging and benign pathologic findings with a low proliferative index is noteworthy and should be recognized in the management of an intracranial lesion in a patient with infantile myofibromatosis. Given de novo formation of a lesion in this adult patient, long-term follow-up is essential in this disease.

To evaluate whether preoperative multirow detector computed tomography (MDCT) findings were associated with clinical outcome 24 months after dynamic stabilization for painful degenerative lumbar spine disease. ⋯ Clinical improvement after dynamic stabilization was significantly associated with 7 independent baseline imaging findings. Preoperative evaluation of these MDCT parameters may improve therapy selection for patients with degenerative lumbar spine disease.

Diffusion tensor imaging (DTI) estimates the course and connectivity patterns of white matter tracts. The objective of this study is to evaluate whether findings in the brain stem modify the preoperative surgical trajectory planning or postoperative outcome in patients with brain stem cavernous malformations. ⋯ Compared with the standard magnetic resonance imaging, DTI provided improved visualization of cavernous malformation involvement in eloquent fiber tracts of the brainstem. This additional information might help in selecting a more appropriate surgical trajectory in selected lesions. Larger patient cohorts are needed to assess the effect of this modality in patients' outcome.

Controlled Clinical Trial
The analysis of the petrosal vein to prevent venous complications during the anterior transpetrosal approach in the resection of petroclival meningioma.
The anterior transpetrosal approach (ATPA) has been used in the resection of petroclival meningioma (PCM) for more than 20 years. Although PCM sometimes involves the petrosal vein and its preservation has been an important issue, the precise risk of petrosal vein sacrifice and subsequent venous complications associated with the use of the ATPA in patients with PCM has not yet been elucidated. ⋯ Our study demonstrated that the ATPA could be performed safely on patients with PCM from the viewpoint of venous preservation. Preoperative CT-DSV is important for assessing the petrosal vein and its tributaries to facilitate a safer operation.

Case Reports Comparative Study
Surgical accuracy of 3-Tesla versus 7-Tesla MRI in Deep Brain Stimulation for Parkinson's Disease.
In deep brain stimulation (DBS), accurate placement of the lead is critical. Target definition is highly dependent on visual recognition on magnetic resonance imaging (MRI). We prospectively investigated whether the 7-T MRI enabled better visualization of targets and led to better placement of leads compared with the 1.5-T and the 3-T MRI. ⋯ Although the 7-T MRI enables a significant better visualization of the DBS target in patients with PD, we found no clinical benefit for the placement of the DBS leads.
