Splenic infarcts are represented by wedge-shaped, oval or linear areas. Haemorrhagic infarcts are characterised by being hyperdense. Disseminated infarction occurs predominantly in myeloproliferative diseases. During the early stages, the infarct appears as an ill-defined hypodense defect, with non-homogeneous contrast enhancement. During the acute and sub-acute stage, the density of the infarct is low and there is no contrast enhancement. During the chronic stage, its density increases and there is slight contrast enhancement. Complications following splenic infarcts, such as abscesses, bleeding and rupture can be demonstrated by CT with great accuracy. Problems in differential diagnosis may occur if there are atypical manifestations of the infarct, with respect to abscess or leukaemic infiltrations.
脾梗死表现为楔形、椭圆形或线状区域。出血性梗死的特征是密度增高。播散性梗死主要发生于骨髓增殖性疾病。在早期,梗死灶表现为边界不清的低密度缺损,增强扫描呈不均匀强化。在急性和亚急性期,梗死灶密度低,无强化。在慢性期,其密度增加,有轻度强化。脾梗死的并发症,如脓肿、出血和破裂,CT能准确显示。如果梗死灶有非典型表现,与脓肿或白血病浸润鉴别时可能会出现问题。
