| congenital pancytopenia | <haematology> A rare inherited type of aplastic anaemia which carries an increased risk to the patient of developing leukaemia. May be treated by bone marrow transplant. Origin: Gr. Haima = blood (13 Nov 1997) |
| congenital paramyotonia | Paramyotonia congenita, a nonprogressive myotonia induced by exposure of muscles to cold; there are episodes of intermittent flaccid paralysis, but no atrophy or hypertrophy of muscles; autosomal dominant inheritance. There is a variant autosomal dominant form in which cold is not a provoking factor. Synonym: Eulenburg's disease. (05 Mar 2000) |
| congenital pneumonia | Pneumonia in the newborn, infection being contracted prenatally. (05 Mar 2000) |
| congenital protein C or s deficiency | This inherited disorder of blood coagulation is characterised by a deficiency of vitamin K dependent plasma proteins (C and s) that are naturally occurring anticoagulants. This disorder results in an increased risk of blood clot formation within the circulatory system. (27 Sep 1997) |
| congenital pulmonary arteriovenous fistula | Abnormal congenital communication between pulmonary arteries and veins usually found in the lung parenchyma. (05 Mar 2000) |

| congenital renal cysts | <radiology> Congenital solitary cyst, multilocular cyst, multicystic disease (renal dysplasia), polycystic disease, autosomal-recessive (childhood) form, autosomal-dominant (adult) form, medullary sponge kidney, medulary cystic disease see also: Potter syndrome (12 Dec 1998) |

| congenital spherocytic anaemia | <haematology> A hereditary disorder that leads to a chronic haemolytic anaemia due to an abnormality in the red blood cell membrane. This disorder is caused by a defective gene. Red cells are resistant to stress and rupture easily. Infants may appear jaundiced and pale. Fatigue, weakness and shortness of breath are other symptoms that may be seen in older patients. The spleen may also be enlarged. Treatment includes splenectomy (removal of the spleen). After this is accomplished the life-span of the red blood cells returns to normal. Origin: Gr. Haima = blood (27 Sep 1997) |
