Aneurysmal bone cysts (ABCs) are benign, slow growing expansile lesions usually found in long bones or vertebrae. Plain radiography reveals expansion of bone and cortical thinning. MRI may assist in diagnosis by virtue of its ability to demonstrate blood-fluid levels, which is a characteristic finding in these lesions. Very few cases of ABC of the paranasal sinuses have been reported in the literature. We present MRI findings of ABC of the ethmoid sinus in a 19-year-old male.
骨囊肿（ABCs）是一种良性、生长缓慢的膨胀性病变，通常见于长骨或椎骨。X线平片显示骨质膨胀和皮质变薄。磁共振成像（MRI）因其能够显示液-液平面而有助于诊断，这是这些病变的特征性表现。文献中报道的鼻窦骨囊肿病例极少。我们报告了一名19岁男性筛窦骨囊肿的MRI表现。
