A 13-year-old girl with a pituitary abscess complained of continuous headache and bitemporal hemianopsia after a common cold. However, she had no inflammatory reactions on admission. Computed tomography showed a low-density sellar mass lesion extending to the suprasellar cistern with a peripheral low-density area, and ring enhancement of the capsule with a particularly thick region. Magnetic resonance imaging showed the mass lesion as a low- and high-intensity area on the T1- and T2-weighted images, respectively. The iso-intense rim of the lesion and the left frontal mass lesion adjacent to the capsule were enhanced by gadolinium-diethylenetriaminepenta-acetic acid. Magnetic resonance imaging also indicated only mild sphenoidal sinusitis which may be representative of the inflammatory process. Careful assessments of neuroimaging findings and preceding trivial inflammatory signs are necessary for the correct diagnosis of a pituitary abscess.
一名13岁的垂体脓肿女孩在感冒后出现持续头痛和双颞侧偏盲。然而，她入院时没有炎症反应。计算机断层扫描显示鞍区有一个低密度肿块病变，延伸至鞍上池，外周有低密度区，包膜呈环形强化，强化区域特别厚。磁共振成像显示，在T1加权像和T2加权像上，肿块病变分别为低强度和高强度区域。钆喷酸葡胺增强扫描显示病变的等强度边缘和与包膜相邻的左侧额叶肿块病变有强化。磁共振成像还显示仅有轻度蝶窦炎，这可能是炎症过程的表现。仔细评估神经影像学表现和先前轻微的炎症体征对于垂体脓肿的正确诊断很有必要。
