A 13-year-old, 5.6-kg castrated-male Maltese was presented for reverse sneezing. A dome-shaped round mass abutting diaphragm was incidentally found ventral to caudal vena cava, which had the same echogenicity and density as that of the liver during ultrasonography and computed tomography, showing isoattenuation with a contrast study. Vascular distribution was identified throughout the mass. A caval foramen hernia (CFH) was diagnosed tentatively, followed by a herniorrhaphy and splenectomy of the chronically congested spleen. The patient had been doing well for 5-month postoperative but died because of aspiration pneumonia. CFH is an extremely rare condition, requiring surgery due to compression of the vena cava. It should be considered as a differential diagnosis when intrathoracic, mass-like lesions are identified near the diaphragm.
一只 13 岁、5.6 公斤的去势雄性马尔济斯犬因反向打喷嚏而就诊。在超声和计算机断层扫描时，意外发现在腔静脉腹侧、尾侧有一个圆形肿块，与膈肌相邻，与肝脏的回声和密度相同，在对比研究中呈等密度。整个肿块均可见血管分布。初步诊断为腔静脉裂孔疝（CFH），随后进行疝修补术和长期充血的脾脏切除术。术后 5 个月，患者情况良好，但因吸入性肺炎而死亡。CFH 是一种极其罕见的情况，由于腔静脉受压，需要手术治疗。当在膈肌附近发现胸腔内类似肿块的病变时，应将其作为鉴别诊断。
