We thank the authors for commenting on our case report.¹ They present an interesting and well-documented case of a solitary fibrous tumor (SFT) in the atrium of the right lateral ventricle to add to the previous cases of intraventricular SFTs in the literature.² The unusual feature of their tumor was its multiloculated cystic nature with enhancing septations. Evidently, the increased awareness among pathologists of intracranial and spinal SFTs may result in the diagnosis being made more frequently. Of clinical relevance is that SFTs, though usually indolent, can behave aggressively with symptomatic recurrences requiring a second surgery or adjunctive radiation therapy.³ Although we agree that MR imaging may have demonstrated T2 hypointensity in our case, due to the presence of calcification, it is unlikely that we could have ruled out a meningioma or a choroid plexus papilloma on that basis alone. As the authors emphasize, the MR imaging features of SFTs are so variable that it would be difficult to differentiate these tumors from meningiomas, hemangiopericytomas, or gliomas with any degree of certainty.
