Clinical Classification Guidelines
Inclusion Terms

- Congenital absence of liver
- Congenital hepatomegaly
Medical Intelligence & Overview
Congenital malformations of the liver are unusual conditions present at birth that affect the structure and function of this vital organ. The ICD-10 code Q44.79 encompasses various rare congenital irregularities of the liver, such as accessory liver tissue, absence of parts of the liver, and abnormal enlargement. Recognizing these conditions is important for proper diagnosis and management, even though many may remain asymptomatic or be discovered incidentally during imaging or surgery.
Causes & Symptoms
Clinical Causes: Genetic factors that influence fetal development Chromosomal abnormalities that disrupt normal organ formation Environmental influences during pregnancy, such as exposure to toxins or infections Unknown factors, as many congenital malformations have no identified cause
Key Symptoms: Often asymptomatic and discovered incidentally during medical imaging Abdominal swelling or a palpable mass in some cases Jaundice or yellowing of the skin and eyes if liver function is affected Abdominal pain or discomfort, especially if liver tissue is enlarged or abnormal Signs of liver dysfunction, such as fatigue, nausea, or easy bruising in some cases
Diagnostic & Treatment
Diagnosis Path: Ultrasound: Often the first step, revealing abnormal liver tissue or absence CT scan or MRI: Provides detailed images to confirm the presence of accessory tissue or absence of parts Biopsy: In some cases, a tissue sample may be examined to understand tissue characteristics and rule out other conditions Liver function tests: To assess whether the liver is functioning properly Genetic testing: May be recommended if other congenital abnormalities are present
Treatment Protocols: Routine monitoring: Many congenital anomalies are benign and require only observation Surgical intervention: May be necessary if the malformation causes symptoms, complications, or affects liver function Supportive therapies: Such as nutritional support or medications to manage symptoms Multidisciplinary care: Collaboration among gastroenterologists, surgeons, and genetic specialists for comprehensive management Follow-up care: Regular assessments to monitor liver health and address any arising issues
