Avoid common mistakes on your manuscript.
Dear Editor,
We read with great interest the case report titled “Lipomatous ependymoma: report of a rare differentiation pattern with a comprehensive review of literature” authored by Kavita Gaur published in the February 2016 issue of Brain Tumor Pathol [1]. In this case report, a “13-year-old girl presenting with left-sided hemiparesis altered sensorium and episodic headache with bouts of projectile vomiting” was described. The authors have expressed that a large heterogeneous intraventricular mass lesion displaying focal calcification and hyperintensity on T1- and T2-weighted fluid attenuated inversion recovery (FLAIR) magnetic resonance images suggested the presence of intratumoral fat. Herein, we demand a correction, in case your readers may be misled by a technical problem. The image which is presented in Fig. 1a as a T1-weighted image is a FLAIR magnetic resonance image, because vasogenic edema surrounding the mass effect in the parenchyma of the right lateral ventricle is hyperintense in Fig. 1a. In T1-weighted images, vasogenic edema is hypointense. Evaluating brain parenchyma and ventricular images together also shows that this is a FLAIR-weighted sequence instead of a T1-weighted sequence. We thought that this mistake is a wrong message given to the readers of your journal, most of whom are not radiologists.
Yours respectfully
