Objective： To evaluate the clinical application of proton magnetic resonance spectroscopy （1HMRS） in patients with radiotherapy treated intracranial tumors. Methods： Forty patients with intracranial tumors underwent multivoxel 1HMRS examination before and after radiotherapy. The concentrations of N-acetyl aspartate （NAA）, choline （Cho） and creatine （Cr） were obtained both in the tumors and the contralateral normal brain regions, The ratios of NANCr, Cho/Cr and Cho/NAA were calculated at the same time and follow-up one year. Results：（1） After radiotherapy, tumors inhibited by radiation had decreased Cho, NAA and Cr on proton MRS. Some cases showed necrotic wave. （2） During the one year follow-up, local tumor recurred in 8 cases and their Cho and Cho/NAA increased high again. Other cases without recurrence, HMRS showed no change. Conclusion： Multivoxel proton MR spectroscopy is available for study of tumor metabolites after radiotherapy and it is a valuable method in the evaluation of radiotherapy treated tumors,

Background tumor involving the septum pellucidum is uncommon. Surgery as the main therapeutic procedure for this lesion is a challenge to neurosurgeons. We analyzed the clinical characteristics and pathological features of septum pellucidum tumor in 41 patients and compared the curative effects of frontal transcortical, trans-sulcal and interhemispheric transcallosal approaches. Methods Clinical characteristics and the pathological features of septum pellucidum tumor were investigated retrospectively in 41 patients. The differences in postoperative residual rates, extents of tumors and resection of normal brain tissues after use of the three approaches in these patients were analyzed statistically. Results Septum pellucidum tumor is more likely to attack young or middle-aged persons. The tumor mainly presents itself as a central neurocytoma or cerebral low-grade glioma in pathology and manifests as intracranial hypertension clinically. No difference was found in the extent of tumor resection but significant difference in the extent of normal brain tissue resection and in postoperative disability rate among the three approaches. The transcortical approach brought about the most serious injury to brain tissue and the highest disability rate, Whereas the frontal transcallosal approach the lightest injury and the lowest disability rate. The injury to brain tissue and the disability rate brought about by the front trans-sulcus approach were between the above two approaches. Conclusions Operation is still regarded the major treatment for septum pellucidum tumor. Transcallosal and trans-sulcus approaches are fit with the concept of minimally invasive surgery, and transcallosal approach is the first choice for septum pellucidum tumor.

This study aims to elucidate the nature of cognitive deficits caused by intracranial tumors, as well as to examine how a surgical operation of the tumor may affect tumor-induced cognitive deficits. The patient group included 43 individuals with meningioma or low-grade glioma admitted to a surgical operation of the tumor. Neuropsychological examination was conducted preoperatively, as well as three and 12 months postoperatively. The control group comprised 31 healthy subjects. In the tumor patients, preoperative cognitive performance was compromised in several cognitive domains as compared to the controls. The tumor patients with frontal and large tumors showed impairment virtually across all cognitive domains. Postoperatively, the cognitive performance of the meningioma and the small tumor group improved in all domains, with the performance of the low-grade glioma group and the large tumor group reflecting more modest cognitive improvement. Most of this improvement did not emerge until the 12 months follow-up. Cognitive impairment due to an intracranial tumor is diffuse affecting most cognitive domains. Cognitive recovery after the surgery is more noticeable in patients with meningiomas and small tumors, and the recovery will require a minimum of one year time-wise. This evidence is of significant value when planning both clinical treatment and rehabilitation of intracranial tumor patients.

Background:Giant colloid cysts (size>3 cm) are very rare with only few reported cases in the literature. Case presentation:We report a case of 44 year female who presented with features of raised intracranial pressure, memory and gait disturbances. CT and MR imaging showed a large colloid cyst at foramen of Monro leading to obstructive hydrocephalus. The patient underwent right interhemispheric transcallosal-transforaminal approach and complete excision of the cyst. Conclusions:For a large size of colloid cyst complete surgical excision is recommended. However deep midline location, proximity to the vital structures and giant size of the lesions make surrounding vital structures vulnerable for injury.

The phosphaturic mesenchymal tumor（mixed connective tissue variant）（PMT-MCT） is a very rare tumor. It always leads to paraneoplastic syndrome known as tumor-induced osteomalacia（TIO） manifested with hypophosphatemia, muscle pain and multiple fractures. intracranial occurrence of this tumor is extremely rare. Here we report a case of a large PMT-MCT occurs simultaneously in the clivus and temporal bone for the first time. The patients complained of bone pain throughout the body for more than 10 years and a gradually worsened hearing loss in the left ear for 3 years. Serum test revealed a low phosphate level. MRI scan demonstrated an enhanced lesion in the clivus and left temporal bone. After subtotal resection, the patient was referred to Gamma Knife radiotherapy. Histopathological sections of the tumor confirmed a diagnosis of PMTMCT. 3 months following the section of the tumor, the patient’s serum phosphorus level normalized and bone pain was significantly relieved. Previous publications and our case indicate complete resection or subtotal resection followed by radiotherapy could provide good prognosis of the tumor.
