| 目的 探讨纵隔血管瘤的多层螺旋CT表现。方法 回顾性分析13例纵隔血管瘤的CT资料，观察病变部位、形状、大小、边缘、密度和强化模式、肿块-心脏大血管界面（MCI）和肿块-肺界面（MPI）及其他征象。结果 13例血管瘤均为单发肿块，边缘模糊，位于前中纵隔6例、前中后纵隔4例、右后纵隔3例。10例呈弥漫性蔓状生长，形态不规则，MCI模糊并轻度占位效应9例、明显占位效应1例；2例呈轻度蔓状生长，哑铃状，并延伸入椎管压迫脊髓；1例呈膨胀性生长，椭圆形。MPI清晰12例，模糊1例。8例为混合密度并周边条索状软组织，2例为均匀密度，3例以脂肪密度为主并结节或条索状软组织，其中5例见静脉石；13例均呈结节状或条索状强化并延迟强化，其中12例见引流静脉、7例见供血动脉；4例合并脾脏血管瘤。结论 纵隔血管瘤CT表现具有一定特征，增强CT扫描有助于准确诊断和术前评估。 |

| Objective To explore the imaging findings of mediastinal hemangiomas (MH) on multi-slice spiral CT. Methods CT findings of 13 patients with MH were analyzed retrospectively. The location, shape, size, margin, density and enhancement pattern, mass-cardiovascular interface (MCI), mass-pulmonary interface (MPI) and other appearances of MH were observed. Results Single mass with obscure margin was found in all 13 patients, located at anterior-middle mediastinum in 6 cases, at anterior-middle-posterior in 4 cases, while at posterior mediastinum in 3 cases. Diffuse pampiniform growth mass was found in 10 cases, with irregular-shape and obscure MCI, while mild and significant mass effect were observed in 9 cases mass and 1 case, respectively. Mild pampiniform growth and dumbbell-shape mass were observed in 2 cases, extended into spinal canal and compressed the spinal cord, and 1 mass showed expansive growth and oval-shape. MPI were clear in 12 cases and obscure in 1 case. Eight masses showed mixed density with stripe-like soft tissue in peripheral area, 2 masses showed homogenous density, 3 masses showed predominant fatty tissue with nodular or stripe-like soft tissue, among which the phleboliths were seen in 5 cases. All 13 masses showed heterogeneously nodular or stripe-like enhancement with delayed-enhancement, while significant draining veins were simultaneously seen in 12 cases, blood supply arteries in 7 cases and splenic hemangioma in 4 cases. Conclusion CT findings of MH are relatively specific. Enhanced CT is valuable for preoperative evaluation and accurate diagnosis of MH. |
