Abstract:
INTRODUCTION:Papillary meningioma is an extremely rare malignant lesion with high degree of invasiveness, high recurrence rate, and perivascular pseudopapillary structure. The incidence of cystic degeneration in papillary meningiomas is relatively low, and cystic papillary meningiomas growing in the ventricle are even rarer. Here, we present a case of cystic meningioma and review the literature to propose the diagnosis, treatment, immunohistochemical features, and prognosis of the same. PATIENT CONCERNS:In July 2013, a 35-year-old male Chinese patient presented with dizziness that lasted for a week, without relief. Magnetic resonance imaging (MRI) revealed a 2.0 cm × 1.5 cm × 3.0 cm-sized mass located in the left lateral ventricle trigone. The tumor was small and likely non-malignant. Therefore, the patient received conservative treatment and regular follow-ups. In June 2017, the patient experienced sudden severe headache, dizziness, and vomiting. DIAGNOSIS AND INTERVENTION:MRI revealed that the mass in the left lateral ventricle trigone had increased to 5.0 cm × 7.0 cm × 8.0 cm over 4 years. The patient underwent surgical resection via the left parietal-occipital approach. Two months postoperatively, the patient received 60 Gy local radiotherapy. The postoperative histopathology suggested that the mass was a cystic papillary meningioma. OUTCOMES:Two years after the operation, the patient was asymptomatic, and no recurrence of the lesion was noted on MRI. CONCLUSION:The diagnosis of intraventricular cystic papillary meningioma depends mainly on its histology and imaging features. Total resection and adjuvant radiotherapy can result in a relatively good prognosis of patients with intraventricular cystic papillary meningiomas.
