Posterior fossa choroid plexus papilloma with focal ependymal differentiation in an adult patient: A case report and literature review
2019, Radiology Case ReportsCitation Excerpt :The most likely sources of these lesions are renal carcinoma and lung carcinoma [18]. The lateral ventricle is the most common site for metastatic spread, and only 0.4% of all ventricular metastases are located in the fourth ventricle [19]. Because reports of the clinical and radiological features of CPP with ependymal differentiation are lacking, the difference in the imaging appearance between CPPs with and without ependymal differentiation is unclear.
A Primer on Secondary Brain Neoplasms: The Essentials
2018, Seminars in RoentgenologyCitation Excerpt :Although a pituitary mass may be favored to be metastatic when there is significant edema or erosive/destructive changes rather than smooth remodeling of the sella, it can be difficult to tell the difference between adenomas and metastatic pituitary lesions when imaging findings are nonaggressive as in Figure 10. Other rare locations for metastatic disease to localize to are the lateral, third, and fourth ventricles.36 The most common tumor types for metastasis to the ventricles are renal cell, lung, and colon carcinomas.37
Solitary choroid plexus metastasis from carcinoma of the oesophagus
2008, Journal of Clinical NeuroscienceCitation Excerpt :On the other hand, symptoms such as motor weakness, seizures, unsteady gait, memory disturbance, personality changes, and visual disturbance were relatively uncommon. Although not often recognized, subarachnoid and intraventricular haemorrhages are not uncommon with intraventricular metastases.11–13 Certainly, this feature has been demonstrated in eight patients.
