Abstract

BACKGROUND

Limited reports exist about intracranial incidental findings on computed tomography (CT) imaging. We studied the frequency of incidental findings on 3000 brain CT scans of trauma patients.

METHODS

Three thousands standard brain CT scans of trauma patients were evaluated for some incidental findings. Cisterna magna was evaluated in 1500 CT scans.

RESULTS

In this study we found 30 incidental abnormalities that include 8 cases of tumor: 3 meningioma, 2 craniopharyngioma, 1 oligodendroglioma, 1 low-grade astrocytoma, and 1 medulloblastoma. Suspect osteoma was found in 3 cases. In 3 cases, abnormal calcification was found in pineal region, basal ganglia, and temporal horn area. Three suspect lipomas were found in midline and near midline of the brain. Arachnoid cyst was found in 7 cases and hydrocephaly in 3 cases. Large cisterna magna (>10 cm(3)) was found in 11 cases.

CONCLUSION

Cisterna magna enlargement was the most common incidental finding and brain tumor and arachnoid cyst were next in frequency.

摘要

背景

关于计算机断层扫描（CT）成像中颅内偶然发现的报道有限。我们研究了3000例创伤患者脑部CT扫描中偶然发现的频率。

方法

对3000例创伤患者的标准脑部CT扫描进行评估，以寻找一些偶然发现。对1500例CT扫描评估了枕大池。

结果

在本研究中，我们发现了30例偶然异常，包括8例肿瘤：3例脑膜瘤、2例颅咽管瘤、1例少突胶质细胞瘤、1例低级别星形细胞瘤和1例髓母细胞瘤。发现3例疑似骨瘤。3例中，松果体区、基底神经节和颞角区域发现异常钙化。在脑中线和中线附近发现3例疑似脂肪瘤。发现7例蛛网膜囊肿和3例脑积水。发现11例枕大池增大（>10 cm³）。
