This review summarized published data about the ultrasound image of the spleen in dogs and cats described as diffuse heterogeneous echogenicity pattern and its metaphorical terms honeycomb appearance, moth-eaten, lacy, marbled, and mottled.
The following words were used to search the indexed articles: (Moth-eaten or mottled or marbled or reticulonodular or lacy) and (spleen or splenic) and (ultrasonography or ultrasound or ecography) and (cat or feline or dog or canine).
In total, 36 articles were initially found, of which 19 were selected. The reticulonodular pattern can be seen in healthy puppies. Although patients with various morbidities may present the pattern of splenic diffuse heterogeneous echogenicity, the higher prevalence in the data collected from the papers included in this review were natural infection by Babesia canis 100% (72/72) or by Ehrlichia canis 100% (17/17) or caused by torsion of the spleen 73.3% (11/15). This pattern is also associated with neoplasia both in dogs and cats.
The use of more precise descriptors, such as diffuse heterogeneous echogenicity pattern, reticular or reticular-nodular pattern, is preferred over metaphorical terms such as lacy, moth-eaten, mottled, or marbled pattern. Discrete diffuse heterogeneous splenic echogenicity patterns can be missed if ultrasonographic examinations are conducted with lower-frequency transducers. Although healthy puppies or patients with various morbidities may present the diffuse heterogeneous splenic echogenicity pattern, higher prevalences were reported in canine patients with natural infection by Babesia canis and Ehrlichia canis.
本综述总结了已发表的关于犬猫脾脏弥漫性不均匀回声模式及其比喻性术语（蜂巢状、虫蚀状、花边状、大理石状和斑驳状）的超声图像的文献数据。
使用以下词汇搜索索引文章：（虫蚀状或斑驳状或大理石状或网状结节状或花边状）和（脾脏或脾）和（超声或超声或超声检查）和（猫或猫科或狗或犬科）。
共初步发现 36 篇文章，其中 19 篇被选中。网状结节模式可见于健康幼犬。尽管患有各种疾病的患者可能会出现脾脏弥漫性不均匀回声模式，但在本综述中包含的论文数据中，该模式的更高患病率为犬巴贝斯虫 100%（72/72）或犬埃立克体 100%（17/17）自然感染或脾脏扭转 73.3%（11/15）。这种模式也与犬猫的肿瘤有关。
与花边状、虫蚀状、斑驳状或大理石状模式等比喻性术语相比，使用更精确的描述符（如弥漫性不均匀回声模式、网状或网状结节模式）更为可取。如果使用较低频率的换能器进行超声检查，可能会错过离散的弥漫性不均匀脾脏回声模式。尽管健康幼犬或患有各种疾病的患者可能会出现弥漫性不均匀的脾脏回声模式，但在犬自然感染巴贝斯虫和埃立克体的患者中，该模式的患病率更高。
