Primary central nervous system lymphoma (PCNSL) is a rare, highly malignant tumor type of the nervous system and is associated with poor prognosis. To investigate the efficacy of current treatment strategies for PCNSL, the present study retrospectively analyzed the clinical and pathological features, imaging results, clinical management, and prognoses of nine patients with PCNSL. Postoperative pathological examination confirmed a diagnosis of lymphoma in all the patients and the adopted treatment regimens were as follows: Stereotactic biopsy in combination with methylprednisolone (MP) and methotrexate (MTX) and/or radiotherapy; craniotomy in combination with dexamethasone or MP and/or radiotherapy; and neuroendoscopic surgery in combination with MP and MTX. The follow-up period was 5–27 months with an average duration of 10.1 months. After the initial three months of follow-up, the clinical symptoms of all the patients were significantly improved, with the tumor disappearing in seven patients and evidently reducing in size in two patients. However, six patients exhibited tumor recurrence, three of whom eventually succumbed to the disease during the follow-up period. Currently, comprehensive treatment strategies based on a combination of stereotactic biopsy, chemotherapy and radiotherapy are recommended for the treatment of PCNSL. However, the effectiveness of these treatments remains unsatisfactory. Thus, future studies are required to investigate methods for improving the efficacy of PCNSL treatment strategies.
Pituitary adenomas are the third most common primary intracranial tumor; however, those with postoperative metastases are very rare and are classically considered as pituitary carcinomas. The field of neurosurgery has struggled with diagnosing and treating these unusual lesions. In this report, we retrospectively analyze the clinical features, imaging findings, pathological characteristics and prognosis of one patient with non-hormone-secreting pituitary adenoma who had multiple intracranial and spinal metastases and underwent four surgeries in a 16-year follow-up period. In addition, on the basis of the existing literature, we explore the underlying mechanisms of, as well as the preventive and therapeutic strategies used to treat, pituitary carcinomas and postoperative metastasis of pituitary tumors.
ABSTRACToperative methods in the treatment of secondary epilepsy from hippocampal lesions. █ MATERIAl and METhODS Selection of PatientsThere were 56 patients enrolled in this study including 31 males and 25 females. These patients were aged 16 to 74 years (mean age, 35.1±13.5 years) and had a history of epilepsy from 2 months to 10 years (mean length, 17.2±13.1 months). The inclusion criteria for patients diagnosed as having hippocampal sclerosis was that systematic anti- █ InTRODuCTIOnMesial temporal lobe epilepsy (MTLE) is the most common type of temporal lobe epilepsy in the clinic, and it tends to develop into medically intractable epilepsy. Hippocampal lesions are the most common cause of MTLE. Currently, the treatment strategy of this epilepsy type remains clinically controversial (16). In this paper, we retrospectively analyzed the clinical data and the outcomes of the microsurgical treatment of 56 patients who had secondary epilepsy from hippocampal lesions and were treated during the period from January 2005 to January 2014. The purpose of this study was to explore the significance of microsurgery and its various AIM: To explore the treatment efficacy of microsurgery for secondary epilepsy from hippocampal lesions. MATERIAl and METhODS:The clinical data, pathological findings, surgical methods and surgical outcomes of 56 patients with secondary epilepsy from hippocampal lesions were retrospectively analyzed. RESulTS:Postoperative pathological examinations confirmed that 27 patients had gliomas, 17 patients had vascular malformations and 12 patients had hippocampal sclerosis. Twenty-nine patients underwent selective resection of the lesioned tissue and the surrounding infiltrated tissue, and 26 patients underwent a more generous removal of the anterior temporal lobe, lesioned tissue, infiltrated tissue and medial structures of the temporal lobe. Fifty patients were followed up with an average follow-up duration of 25.5 months. At postoperative one year, the remission rate of epilepsy that achieved Engel grade I was 80.8% (21/26) and 83.3% (20/24) for the selective resection and more generous resection, respectively, indicating that the difference between the two methods was insignificant.COnCluSIOn: Microsurgery is the first choice for the treatment of secondary epilepsy from hippocampal lesions. Various operative routes and methods can be selected based on the lesion natures. Long-term favorable outcome of seizure control following microsurgery can be achieved in most of the patients.
