==Overview==
Liver mass must be differentiated from the diseases that cause abdominal pain, pruritus, low-grade fever, and ascities such as [[angiomyolipoma]], [[adenoma]], borderline (high-grade [[Dysplasia|dysplastic]]) [[Nodule (medicine)|nodule]], [[cholangiocarcinoma]], confluent [[fibrosis]], [[focal nodular hyperplasia]], focal fat sparing and deposit on [[liver]], [[gallbladder cancer]], hereditary hemorrhagic [[telangiectasia]], inflammatory pseudotumors, liver [[hemangioma]], [[hepatoblastoma]] in children, pyogenic [[Liver abscess|liver abscesses]], [[pancreatic cancer]], [[Stomach cancer]].

Liver mass may be differentiated according to clinical features, laboratory findings, imaging features, histological features, and genetic studies, from other diseases that cause abdominal pain, pruritus, low-grade fever, and ascities. Common differential diagnosis includes: liver abscess, simple liver cyst, and fungal infections.

Overview

Liver mass must be differentiated from the diseases that cause abdominal pain, pruritus, low-grade fever, and ascities such as angiomyolipoma, adenoma, borderline (high-grade dysplastic) nodule, cholangiocarcinoma, confluent fibrosis, focal nodular hyperplasia, focal fat sparing and deposit on liver, gallbladder cancer, hereditary hemorrhagic telangiectasia, inflammatory pseudotumors, liver hemangioma, hepatoblastoma in children, pyogenic liver abscesses, pancreatic cancer, Stomach cancer.

Common Differential Diagnosis

Liver mass must be differentiated from the following diseases that cause abdominal pain, pruritus, low-grade fever, and ascities such as:[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][16][17][18][19][20][21][22][13][23][24][25][26][27]

Abbreviations: RUQ= Right upper quadrant of the abdomen, LUQ= Left upper quadrant, LLQ= Left lower quadrant, RLQ= Right lower quadrant, LFT= Liver function test, SIRS= Systemic inflammatory response syndrome, ERCP= Endoscopic retrograde cholangiopancreatography, IV= Intravenous, N= Normal, AMA= Anti mitochondrial antibodies, LDH= Lactate dehydrogenase, GI= Gastrointestinal, CXR= Chest X ray, IgA= Immunoglobulin A, IgG= Immunoglobulin G, IgM= Immunoglobulin M, CT= Computed tomography, PMN= Polymorphonuclear cells, ESR= Erythrocyte sedimentation rate, CRP= C-reactive protein, TS= Transferrin saturation, SF= Serum Ferritin, SMA= Superior mesenteric artery, SMV= Superior mesenteric vein, ECG= Electrocardiogram
