====== Inflammatory pseudotumor of the choroid plexus ====== A case of [[inflammatory pseudotumor]] is described, in which CT revealed a hyperdense [[intraventricular lesion]] with a trapped [[temporal horn]], and MR imaging showed decreased [[T1]] and markedly [[hypointense]] [[T2]] signal with homogeneously intense enhancement. Radiologically and grossly the tumor resembled a [[meningioma]]; however, histologically it was composed purely of inflammatory, nonneoplastic components. The lesion was resected with no [[evidence]] of [[recurrence]] at 5-month follow-up ((Bramwit M, Kalina P, Rustia-Villa M. Inflammatory pseudotumor of the [[choroid plexus]]. AJNR Am J Neuroradiol. 1997 Aug;18(7):1307-9. PMID: 9282860.)).
