The utility of diffusion-weighted imaging (DWI) for the diagnosis of intracranial abscesses has already been established. However, the use of DWI for pituitary abscesses has not been previously reported. We present a case of postoperative pituitary abscess in which T1-weighted and T2-weighted magnetic resonance imaging (MRI) revealed a supra-sellar cystic mass, with the cyst contents showing high intensity on DWI. This case suggests that DWI is useful for the diagnosis of pituitary abscesses.
弥散加权成像（DWI）在颅内脓肿诊断中的效用已经得到证实。然而，DWI在垂体脓肿诊断中的应用此前尚未见报道。我们报告一例垂体脓肿术后病例，其T1加权和T2加权磁共振成像（MRI）显示鞍上囊性肿块，囊肿内容物在DWI上呈高信号。该病例提示DWI对垂体脓肿的诊断有用。
