An ectopic (or "wandering") spleen results from abnormal ligamentous laxity failing to fixate the spleen in its normal location in the left upper quadrant. Ligamentous laxity can be acquired due to conditions, such as splenomegaly or pregnancy, but is often congenital. Because of this laxity, there is an elongated vascular pedicle, which is prone to torsion and resultant splenic infarction. These patients generally present with abdominal pain and other nonspecific symptoms making the diagnosis very difficult to make clinically. As such, the radiologist plays a crucial role in the diagnosis and care of these patients, as often the diagnosis is only considered after imaging.
异位（或“游走”）脾是由于韧带松弛异常，未能将脾脏固定在左上腹的正常位置所致。韧带松弛可能是由于脾肿大或妊娠等情况后天获得的，但通常是先天性的。由于这种松弛，会出现细长的血管蒂，容易发生扭转并导致脾梗死。这些患者通常表现为腹痛和其他非特异性症状，使得临床诊断非常困难。因此，放射科医生在这些患者的诊断和治疗中起着至关重要的作用，因为通常只有在进行影像学检查后才会考虑诊断。
