Background Cardiac myxoma is the most common cardiac tumor. Neurologic complications are seen in 20%-35%, most frequently embolic ischemic stroke, and rarely secondary to intracranial aneurysms. The mechanism of aneurysm formation in these patients is speculative. Methods We report, herein, a 37-year-old male with a cardiac myxoma who experienced repeated ischemic stroke and intracerebral hematoma despite resection of heart tumor, secondary to multiple cerebral aneurysm. Results We offered him surgery with a bypass and clipping, because growing of aneurysm was not suitable for endovascular treatment. Conclusion Bypass and clipping are possible options in this type of disease. Aneurysm biopsy supports mycotic theory of aneurysm formation. © 2015 National Stroke Association.

Hirayama disease, or juvenile amyotrophy of distal upper extremity, is a benign, self-limiting cervical myelopathy consisting of selective unilateral weakness of the hand and forearm. The weakness slowly progresses until spontaneous arrest occurs within 5 years of onset. The condition predominantly affects Asian males and is thought to be secondary to spinal cord compression during neck flexion, because of a forward displacement of the posterior dural sac. The authors present what is to their knowledge the first reported case of a Caucasian male with a severe form of Hirayama disease, suffering from weakness of the leg as well as the forearm. An abnormal range of cervical flexion was observed at the C5-6 level. The patient was successfully treated by anterior cervical discectomy and fusion.

Trigeminal neuralgia is produced in a significant number of cases by vascular compression at the level of cisternal segment of the nerve at the entry of the pons. It is common to find superior cerebellar artery (SCA) responsible for this compression. The retrosigmoid approach (RA), with asterional craniectomy, clearly exposes the cisternal portion of the trigeminal nerve (TN).We describe in this case report how vessels at the trigeminal pore level known as Meckels segment can compress the TN. This situation is unusual. One of the reasons why the compression of this Meckels segment level could be overlooked is a suprameatal tubercle (ST) prominence that would prevent trigeminal pore visualization through retrosigmoid approach.The suprameatal extension of this approach has been described for other purposes, especially in tumors invading Meckels cave resection. We could not find publications for the use of the resection of the suprameatal tubercle in the retrosigmoid approach for microvascular decompression of the trigeminal neuralgia.Microvascular decompression of the TN is an effective treatment for trigeminal neuralgia, however in some cases, in which vascular compression is not evident when exploring the cerebellopontine angle, it is important to note that association of a prominent ST can hide a vascular compression of the nerve in this region.
