Meningeal Melanomatosis with a Spinal Meningeal Melanocytoma Trigger by an in vitro Fertilization.

Meningeal melanomatosis is an infrequent tumor originating from the melanocytes in the leptomeninges and one of the recognized primary melanocytic tumors of the central nervous system. The average survival has known to be about 5 months. It can be associated with solid tumors, such as meningeal melanocytomas. The patient we present was diagnosed of a meningeal melanomatosis that developed two solid tumors related to an in vitro fertilization. The clinical course was rapidly fatal. Although the use of comprehensive diagnostic procedures, usually the final diagnosis of primary diffuse meningeal melanomatosis is postmortem, it would be advisable for the appropriate management of the patient to make a differential diagnosis and to be aware of the behavior of the tumor.

Brain Metastases of Non-Small Cell Lung Cancer: Prognostic Factors in Patients with Surgical Resection.

BACKGROUND AND STUDY AIMS: Bronchogenic carcinoma is the cancer that most commonly metastasizes to the brain. The standard treatment schedule for these patients is still unclear, although recommendation level 1 class I advocates for surgical resection together with postoperative whole-brain radiotherapy for patients with good Karnofsky performance status (KPS). We performed a study to identify prognostic factors for the long-term survival of patients with brain metastases from non-small cell lung cancer (NSCLC). PATIENTS: This retrospective single-center study included 71 patients with brain metastases from NSCLC having undergone surgical metastasectomy between January 2002 and January 2015. RESULTS: The average age was 58.8 years. A total of 85.9% of the lesions were located in the supratentorial region, 61.9% of the lesions were < 3 cm, and 80.3% of cases were solitary brain metastases. Complete resection was achieved in 90.1% of patients. Clinical debut with motor involvement was associated with higher rates of incomplete surgical resection. Patients with motor deficits had a worse preoperative KPS. The preoperative KPS was > 70 in 74.6% of patients, and the postoperative KPS was > 70 in 85.9% of patients. Overall, 84.5% of the brain surgeries had no complications. Brain metastases were diagnosed as a synchronous presentation in 64.7% of patients.The average survival after brain surgery was 20.38 months. The survival rate was 66.2% at 6 months, 45.1% at 12 months, 22.5% at 24 months, 14.1% at 36 months, and 8.5% at 48 months. Patients < 55 years of age showed a higher survival rate at 12 months and 48 months. Patients > 70 years of age showed a higher mortality rate at 6 months. Complete surgical brain metastasis resection was associated with an increased survival at 6 months, and patients undergoing primary lung surgery had better survival rates at 48 months. A preoperative KPS > 70% improved the prognosis of patients at 6 and 24 months. Surgical complications reduced survival at 6 and 12 months. CONCLUSION: Surgical resection may be beneficial for a given group of patients: a preoperative KPS > 70; age < 55 years, complete surgical brain metastasis resection, no surgical complications, patients with primary lung surgery, and complete radiotherapy treatment. We did not find any significant difference regarding further factors that probably affect survival rates such as size or number of metastases.

Rosette-forming glioneuronal tumour of the fourth ventricle. Not always a foreseeable development.

AIM OF THE STUDY: Rosette-forming glioneuronal tumour (RGNT) of the fourth ventricle is an uncommon tumour. The management is not consensual. Most of the published cases show stable outcome with and without gross total resection and are regarded as having a relatively indolent behaviour. MATERIAL AND METHODS: We present a 32-year-old man with a tumour in the fourth ventricle. He underwent midline suboccipital craniectomy with gross total removal. RESULTS: The histopathological diagnosis was RGNT grade I. Four years later he presented a radiological progression and received stereotactic radiosurgery. At the last follow-up seven years after surgery, the MRI showed no recurrence. CONCLUSIONS: RGNT should be considered in the differential diagnosis of a posterior fossa tumour and has to be differentiated from other lesions for its indolent course and favourable prognosis. Surgical procedures should be carefully performed to avoid serious surgical morbidities. Stereotactic radiosurgery treatment appears to be a useful treatment in recurrence episodes.
