Enhancing diagnostic accuracy for a rare brain tumor: This study analyzes the imaging findings of papillary glioneuronal tumors (PGNTs), aiming to improve preoperative diagnosis of this rare tumor type. By examining the clinical and imaging characteristics of 36 pathologically confirmed PGNT cases, the research seeks to identify key features that can aid in accurate and timely diagnosis. The study retrospectively analyzed the clinical and imaging manifestations, including CT and MRI findings, of the PGNT cases. Lesion location, cystic and solid components, presence of edema or hemorrhage, and calcification patterns were evaluated. Ultimately, the findings reveal that PGNTs typically manifest as cystic masses with mural nodules or mixed cystic and solid masses in the white matter around the supratentorial ventricle. Specific features such as “T2-FLAIR mismatch” in cystic lesions and the presence of septations, calcification, or hemorrhage were also highlighted. These imaging characteristics can help clinicians differentiate PGNTs from other brain tumors and improve diagnostic accuracy.
Published in Neurosurgical Review, this study is highly relevant to the journal's focus on neurological disorders and surgical interventions. By analyzing the imaging characteristics of papillary glioneuronal tumors, the research provides valuable insights for neurosurgeons and radiologists involved in the diagnosis and management of these rare tumors, ultimately improving patient care.
