Congenital anomaly: Something that is unusual or different at birth.
A minor anomaly is defined as an unusual anatomic feature that is of no serious medical or cosmetic consequence to the patient. A minor anomaly of the feet might, for example, be curvature of the second toe so it overlaps the third toe a little.
A major anomaly, by contrast, might be a cleft lip and palate, a birth defect of serious medical and cosmetic consequence to the child.
The word “congenital” means “at birth.” “Anomaly” comes from the Greek word “anomalos” meaning “uneven” or “irregular.”
- Congenital arthrogryposis
Congenital arthrogryposis: Nonprogressive congenital contractures that develop before birth and are evident at birth (congenital). The contractures are characterized by reduced mobility of many (multiple) joints. Congenital arthrogryposis is also called arthrogryposis multiplex congenita (AMC). In AMC the range of motion of the joints in the arms and legs is usually limited or fixed. Joints […]
- Congenital bilateral absence of vas deferens
Congenital bilateral absence of vas deferens: A condition in males when the tubes that carry sperm from the testes (the vas deferens) fail to develop normally. The testes usually develop and function normally and the men have normal sexual performance, but sperm cannot be transported through the male reproductive system. Men with congenital bilateral absence […]
- Congenital central hypoventilation syndrome
Congenital central hypoventilation syndrome: Failure from birth of central nervous system control over breathing while asleep. There are usually no breathing problems while awake. The involuntary (autonomic) control of respiration is impaired, but the voluntary control of ventilation which operates during waking hours is generally intact. The neurologic problem can extend to the control over […]
