In addition to the previous 5 cases of skull base osteoma with radiologic information reported in the English literature, this is the sixth case report of this rare disease. ⋯ A satisfactory 1-stage resection of the 2 contiguous lesions via a modified anterior transpetrous approach was performed.

Mild traumatic brain injury (mTBI), defined as blunt trauma to the head resulting in witnessed loss of consciousness, definite amnesia, or witnessed disorientation with a Glasgow Coma Scale (GCS) score of 14 or 15 is a common occurrence in the emergency department. In mTBI, oral anticoagulation is known to be an important risk factor for hemorrhage. Clinical guidelines recommend baseline computed tomographic (CT) scan and observation for 24 hours plus a CT scan before discharge. ⋯ Patients with a GCS score of 15 who are taking long-term anticoagulation therapy and who present with mTBI have a risk of cranial hemorrhage that is likely to be similar to that of non-anticoagulated patients. It may be reasonable to envision a protocol including only one CT scan and an appropriate observation period.

The aims of this study were to characterize the epidemiologic, histologic, and radiologic aspects of sphenopetroclival meningiomas (SpPCMs) and to evaluate the outcome of Gamma Knife radiosurgery (GKRS) either as an adjunct to microsurgery or as a primary SpPCM treatment modality. ⋯ GKRS can be an effective alternative treatment for controlling the progression of SpPCM tumors, producing appropriate clinical outcomes and few complications.

Brain & Music: an intraoperative stimulation mapping study of a professional opera singer.
Music is one of the most sophisticated and fascinating functions of the brain. Yet, how music is instantiated within the brain is not fully characterized. Singing is a peculiar aspect of music, in which both musical and linguistic skills are required to provide a merged vocal output. Identifying the neural correlates of this process is relevant for both clinical and research purposes. ⋯ ISM and a tailored music battery enabled better characterization of a specific network within the brain subserving score reading independently from speech with long-term clinical impact.

There is no published report of ruptured cerebral aneurysm accompanied by target vessel occlusion. We present a case of ruptured basilar tip aneurysm with concomitant basilar artery (BA) occlusion. ⋯ We were able to recanalize the BA trunk and perform coil embolization of the ruptured BA tip aneurysm. Our case is the first published report of a ruptured aneurysm with target large-vessel occlusion. Awareness of the issues raised in this case is required to determine the best treatment strategy, and preoperative consideration allows neurointerventionalists to avoid unpleasant surprises in the angiography suite.
