Awake craniotomy is a frequent procedure in the practice of neurosurgery. In functional neurosurgery, this anesthetic technique has been described for Deep-Brain- Stimulators (DBS) placement Parkinson’s disease and tumor resection eloquent areas. We describe case transoperative identification epileptogenic foci with successful real-time resection. A 26-year-old patient who presented to our emer...

Objective Brain mapping techniques allow one to effectively approach tumors involving the primary sensory-motor cortex and nearby area (M1). Tumor resectability maintenance of patient integrity depend on ability successfully identify motor tracts during resection by choosing most appropriate neurophysiological paradigm for mapping. Mapping with a high frequency (HF) stimulation technique has em...

Introduction: The endoscopic transsphenoidal approach for pituitary adenomas and other sellar lesions is quickly becoming the procedure of choice in their surgical management. The most common approach is binostril three-hand technique which requires a large exposure and subjects both nasal cavities to potential trauma. To reduce nasal morbidity, we employ a mononostril two-hand technique with t...

five cases of giant cell tumor of the lower end of radius are reported. three of the patients were women and two were men, the youngest of the patients was 18 years old and oldest 37 years. en bloc resection followed by reconstructive procedures were performed in three of the cases with good results.

Abstract Neural stem cells (NSCs) harboring cancer-driving mutations in the subventricular zone (SVZ) have recently been reported as of origin for human GBM. However, pathological role residual tumor-initiating NSCs (tNSCs) SVZ is undetermined recurrent tumors after surgical removal primary tumor. After resection GBM, most recurrences still appear local around cavity (RC). Accordingly, removal,...

BACKGROUND Colorectal cancer is the third leading cause of death worldwide. Currently, novel chemotherapeutic agents are first-line therapy for unresectable stage IV colorectal cancer, while benefits of noncurative primary tumor resection in advanced disease remain debatable. OBJECTIVE This meta-analysis evaluated outcomes of patients with unresectable stage IV colorectal cancer receiving sys...

introduction hemangiopericytomas (hpcs) are rare neoplasms which account for approximately 1% of primary vascular tumors. case presentation we report a 73 years old woman with vague abdominal pain who did not have further significant symptoms and was diagnosed to have retroperitoneal hemangiopericytoma. discussion the tumor was initially diagnosed by ultrasound evaluation. mri showed a lobulate...

conclusions the authors emphasize on the rarity of this pathology among children, its clinical polymorphism, the necessity of a rapid diagnosis, and an appropriate treatment to avoid complications and recurrence of the tumor. introduction right atrial myxoma is a rare disease among children and its clinical presentation is not specific. case presentation we reported a four-year-old girl with ex...

calcifying epithelial odontogenic tumor (ceot) is a rare benign, but locally infiltrating odontogenic neoplasm. it accounts for less than 1% of all odontogenic tumors. this is a case report of recurrent ceot in the maxilla. a 35-year-old patient reported after three years of surgical excision of the lesion, with a recurrence. it is of particular concern because of its anatomic location in the m...
