肝臟囊腫是肝臟內充滿液體的囊性病變，可為先天性或後天性。多數為偶然發現的良性病變，但需與膽管囊腺瘤或膿瘍等鑑別。
貓肝臟囊腫罕見。波斯貓可合併多囊腎與多囊肝。
犬肝臟囊腫罕見，多為偶然超音波發現。先天性多囊肝病偶見於 Cairn Terrier 等品種。多數單純性囊腫無臨床意義。
建議：含 Dextrose 的晶體液 (2.5-5% Dextrose)，避免 LRS（肝功能不全時乳酸代謝差）
類型：LRS
監測頻率：每日觀察

建議數日內就診評估，非立即危及生命但不宜拖延 (evaluation within days recommended, not immediately life-threatening)
單純性肝臟囊腫預後極佳，多數不影響生活品質與壽命。多囊肝病視肝功能受損程度而定。腫瘤性囊腫需依組織學類型評估預後。
Diagnostic Approach for Hepatic Cyst
Evaluate for jaundice, ascites, hepatomegaly, neurological signs (hepatic encephalopathy)
Serum chemistry (ALT, ALP, GGT, bilirubin, albumin, BUN), serum bile acids, ammonia
Abdominal ultrasound; coagulation profile before biopsy; percutaneous or laparoscopic liver biopsy
