Neonatal cholestasis is far less common than unconjugated hyperbilirubinemia. Despite its relative infrequency, neonatal cholestasis is always pathologic. Therefore, the clinician should consider the possibility of cholestasis in a jaundiced infant. This case was a 50days girl with cholestasis and abdominal distention due to huge hemangioma.
Keywords: cholestasis, hyperbilirubinemia, infants, hepatic neoplasms, liver enzymes
Cholestasis refers to impedance to bile acid formation or flow and is evidenced by elevated conjugated or direct hyperbilirubinemia. An elevated direct bilirubin as greater than 1.0 if the total bilirubin is less than 5.0; and greater than 20% of the total bilirubin if the total bilirubin is greater than 5.0. Unlike neonatal unconjugated (indirect) hyperbilirubinemia, which is more frequently physiologic rather than pathologic, conjugated hyperbilirubinemia should always be viewed as abnormal and should not be ignored. Early recognition of cholestasis in infants and prompt diagnosis of the underlying disorder are imperative to identify those disorders that respond to specific treatment. It is therefore recommended that any jaundiced infant have total and direct bilirubin checked at 2 to 3weeks of age.1‒7
More common causes of neonatal cholestasis6
Obstructive: Biliary Atresia, Choledochal Cyst, Hemangioma, Hepatoblastoma, Gallstones/Biliary Sludge, Inspissated Bile (Due To Hemolysis), Alagille Syndrome (Biliary Hypoplasia), Cystic Fibrosis.
Hepatocellular: Idiopathic neonatal hepatitis, Viral (CMV, HIV), Bacterial, Urinary tract infection, Sepsis, Syphilis.
Genetic/Metabolic: 1-Antitrypsin deficiency, Cystic fibrosis, Hypothyroidism, hypopituitarism, Tyrosinemia, Galactosemia, Progressive familial intrahepatic cholestasis, Cystic fibrosis.
Toxic: Total parenteral nutrition.
Drugs: Most infants with neonatal cholestasis present with jaundice, dark urine, a colic stools, and varying degrees of hepatomegaly. It is necessary to evaluate infants for evidence of congenital anomalies, splenomegaly, skin rash, and neurologic signs. Cholestatic jaundice because of hemangioma -related bile duct compression.7,8
Hepatic hemangioma, also known as hepatic venous malformations, is benign non-neoplastic hyper vascular liver lesions. They are frequently diagnosed as an incidental finding on imaging, and most patients are asymptomatic. From a radiologic perspective, it is important to differentiate hemangioma from hepatic neoplasms. Hepatic hemangioma is thought to be congenital in origin, non-neoplastic, and is almost always of the cavernous subtype. Blood supply is predominantly hepatic arterial, similar to other liver tumors. A peripheral location within the liver is most common.8‒10
A 50 days' girl with birth weight 3 kg now was 5 kg, NVD delivery without any complication. The infant was icteric in 35 days. In 40 days she admitted in ward so in history every things was normal and her mother was normal and she never use any drugs or smoking. In physical examination the infant was so generalized icteric abdominal distention, umbilical hernia, edema and respiratory distress. Liver was huge and span 10 cm, spleen was palpable.
The laboratory tests were
Blood investigations revealed anemia (Hb 7gm/dl), normal total and differential leukocyte count and severe thrombocytopenia (platelet count 70,000/μL), AST 200, ALT 450, ALK 678, GGT 150, T. Billi 10 mg/dl, D 6mg/dl, PT 16 sec, PTT 30sec, INR 2U/A-U/C were normal. Other biochemistry lab test was normal. TORCH study, viral marker hepatitis, TFT, B/C and metabolic study were normal. HIDA scan was normal. Chest X ray was normal. Brain and pelvic CT were normal. In sonography typically well-defined hyperechoic lesions was seen in left lobe. So contrast abdominal spiral CT was done and in CT well defined enhance lesion was seen due to liver hemangioma (Figure 1). So surgical consult was done then the infant transfer to surgery ward and the left lobe of liver was lobectomy and after 2 weeks the T. Billi 3D1 and after 2 months the infant was good and lab test were normal.
Cholestasis refers to impedance to bile acid formation or flow and is evidenced by elevated conjugated or direct hyperbilirubinemia.

Unlike neonatal unconjugated (indirect) hyperbilirubinemia, which is more frequently physiologic rather than pathologic, conjugated hyperbilirubinemia should always be viewed as abnormal and should not be ignored.
Urinary tract infections are an important cause of cholestasis in otherwise well-appearing infants, so urinalysis and culture should be routinely included in the initial stages of evaluation. The newborn screen results should be reviewed, with particular attention to the possibility of hypothyroidism, galactosemia, and cystic fibrosis. Urine-reducing substance (for galactosemia) and additional infant testing for thyroid function can also be considered. Knowledge of any maternal–infant blood group incompatibility is useful; as hemolysis can contribute to cholestasis via inspissate bile. CBC may provide evidence of sepsis or hemolysis. Liver enzymes ALT, AST, alkaline phosphatase, and GGT are included in the evaluation, although none is capable of diagnosing a particular condition. Protime/INR and albumin are tests of hepatic protein synthetic function.1-10
Hepatobiliary ultrasonography can make or exclude the diagnosis of choledochal cyst, as well as suggest (but not diagnose or rule out) biliary atresia. Hepatobiliary scintigraphy (e.g., HIDA scan), after 3 to 5 days of premedication with Phenobarbital, is used by many to exclude biliary atresia, if the test is negative (isotope passing from the liver into the intestine).9

Sub types
The presence of a few hepatic hemangiomas in the liver is not uncommon, but rarely a large number hepatic hemangioma may occur.12 Most hemangioma is relatively well defined. The dynamic enhancement pattern is related to the size of its vascular space.
Features of typical lesions include:
Recommendations for patients with no known risk factors for hepatic malignancy can range from center to center from performing confirmatory examinations (MR imaging, triphasic CT or scintigraphy) to considering follow-up ultrasound in 6 months to confirm stability, to performing no further imaging evaluation. Some authors propose surgical resection for patients with progressive abdominal pain in combination with size greater than 5cm .13,14 So we should know one of the causes of cholestasis is liver hemangioma with pressure in bile duct that can see in sonography and abdominal CT and with surgery the symptom was removed.
None.
