Microsurgery and radiosurgery for brainstem cavernomas: effective and complementary treatment options.
To evaluate treatment options for brainstem cavernous malformations (BSCMs) using the results from a center with long-standing experience in microsurgical resection and Gamma Knife radiosurgery (GKRS) treatment of BSCMs. ⋯ In the treatment of BSCM, patient selection and timing of surgery are crucial. If applied in a multidisciplinary neurosurgical center, microsurgery and radiosurgery are complementary treatment options that both result in reduced bleeding rates and improvement of clinical outcome.

Microvascular decompression (MVD) is an established surgical therapy for patients with idiopathic trigeminal neuralgia (TN). The role of MVD in patients with definite or suspected multiple sclerosis (MS) remains controversial. ⋯ Facial pain outcomes after MVD in patients with suspected MS-related TN are poor compared with outcomes for patients with idiopathic TN. This study provides further support that many patients with MS-related TN have pain that is centrally mediated, reducing the effectiveness of procedures performed on the trigeminal root, ganglion, or divisions.

This study was undertaken primarily to investigate the possible prognostic values of several cell-cycle regulators for the prediction of functioning pituitary adenoma (FPA) recurrence after surgical resection by immunohistochemically analyzing tumor samples obtained by surgical resection. ⋯ Our findings indicate that p16, pRB protein, and cyclin D1 are associated with recurrence FPA after surgical resection.

Infection associated with an intracranial meningioma is an extremely rare condition. Only six cases have been described in the literature. Because of its dual pathologies, initial radiologic diagnosis can be difficult. We present the first reported case of multiple infected intracranial meningiomas and correlate the radiologic and histologic findings. ⋯ In the appropriate clinical context, diffusion-weighted imaging and apparent diffusion coefficient map aid the diagnosis of infected intracranial meningiomas.

Plastic clips are made of diamagnetic material and may result in fewer computed tomography (CT) and magnetic resonance artifacts than titanium clips. Considering that polymer plastic clips are increasingly being used in endoscopic surgery, our study examined the CT and magnetic resonance imaging (MRI) characteristics of plastic clips after application in the neurocranium and compared them with titanium clips. ⋯ The plastic clips are made of a diamagnetic, nonconductive material that results in fewer CT and MRI artifacts than titanium clips.
