Stereotactic Radiosurgery for Trigeminal Neuralgia Caused by Vertebrobasilar Compression: A Report of Four Cases.

Background: Microvascular decompression (MVD) of the trigeminal nerve is an effective procedure for treating patients with trigeminal neuralgia (TGN). However, vertebrobasilar decompression involves technical difficulties and demonstrates a higher risk of minor trigeminal hypesthesia/hypalgesia, transient diplopia, and hearing loss. Stereotactic radiosurgery (SRS) has been an effective alternative treatment for TGN.

Cerebellar Hemangioblastoma Associated With a Vascular Malformation: A Case Report Treated With Surgery and Radiosurgery.

Hemangioblastoma is well known as an essentially benign cystic and/or solid tumor classified WHO grade I, mainly originated in the posterior fossa. One of the characteristics of this tumor is very rich vasculature in and around the tumor. We have encountered a case of hemangioblastoma in association with a vascular anomaly near the tumor, though they were located separately by the tentorium.

Neuroendocrine Carcinoma of Uterine Cervix: Stereotactic Radiotherapy for Brain Metastasis and Stereotactic Body Radiotherapy for Renal and Pancreatic Metastases.

A case of cervical neuroendocrine carcinoma (NEC) of the uterine cervix (NECUC) was presented. After total hysterectomy with bilateral salpingo-oophorectomy and adjuvant chemotherapy, a left renal tumor and a pancreatic lesion developed and were both diagnosed on pathological examination as metastases from NEC. In addition, a brainstem metastasis causing neurologic signs developed.

Stereotactic Radiosurgery and Stereotactic Radiotherapy for Malignant Skull Base Tumors.

The role of stereotactic radiosurgery/stereotactic radiotherapy (SRS/SRT) for malignant skull base tumors was summarized and discussed. The treatment of skull base tumors remains challenging. Their total resection is often difficult.

One-Day Two-Fraction Radiosurgery for Brain Metastases Using Gamma Knife.

Objective: We aimed to evaluate the feasibility of a one-day two-fraction Gamma Knife radiosurgery (GKRS) for brain metastases.

Cases And Methods: Ten cases with ten brain metastases (four cases of lung adenocarcinoma, one small cell lung carcinoma (SCLC), two renal cell carcinoma, one breast cancer, one esophageal carcinoma, and one bile duct carcinoma) were treated by one-day two-fraction (with an interval of more than six hours) GKRS under rigid skull frame fixation. Of the ten brain metastases, five lesions were in the frontal lobe, one in temporal, one in occipital, and three in the cerebellar hemisphere.

[Spontaneous extra-cranial vertebral artery dissection accompanied with multiple cerebral infarctions due to re-canalization].

In this paper we report a case of vertebral artery occlusion caused by spontaneous extra-cranial vertebral artery dissection accompanied with cerebellar and thalamic infarctions due to recanalization. Furthermore, after a nine-week time lapse we performed PTA/stenting. A 62-year-old man with vertigo, dysarthria and nuchal pain without injury was admitted to our hospital.

[A case of treatment on traumatic pseudoaneurysm of internal carotid artery occurred epistaxis].

We reported a case of traumatic pseudoaneurysm of internal carotid artery accompanied by skull base fracture, for which Guglielmi detachable coil(GDC) embolization surgery was very effective for recovery. A 53-year-old man met a traffic accident and was admitted to our hospital with blindness and epistaxis accompanied with shock. Balloon occlusion test showed a positive sign of traumatic pseudoaneurysm of internal carotid artery, and under the diagnosis GDC embolization surgery was performed on six days after the onset.
