Non-ischemic Cerebral Enhancing (NICE) Lesions Following Endovascular Treatment of Intracranial Aneurysms: A Case Report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Non-ischemic cerebral enhancing (NICE) lesions are a rare complication following endovascular therapy (EVT) for intracranial aneurysms, presenting as delayed-onset enhancing lesions on MRI. While their pathophysiology remains unclear, NICE lesions can pose diagnostic challenges due to their resemblance to neoplastic or infectious processes. We report a case of a 67-year-old female with incidental anterior communicating artery (ACom) and posterior inferior cerebellar artery (PICA) aneurysms treated with EVT using a flow diverter for the PICA aneurysm and stent-assisted coiling for the ACom aneurysm. Three months post procedure, a follow-up MRI revealed punctate, nodular, and annular enhancing lesions with peri-lesional edema, consistent with NICE lesions. Despite these findings, the patient remained asymptomatic, reporting only subjective fatigue. She was treated with a one-month course of glucocorticosteroids, leading to symptom resolution. Serial MRI over one year demonstrated a reduction in edema, though new lesions appeared. This case underscores the importance of long-term imaging surveillance following EVT for cerebral aneurysms, as NICE lesions may persist, regress, or evolve over time. Although the clinical course may be benign in some patients, the presence of persistent or newly emerging lesions raises concerns regarding their underlying mechanisms and potential long-term impact. Further research is needed to better understand the pathophysiology, optimize management strategies, and refine follow-up protocols for patients with NICE lesions after EVT.
