QUESTION
Which of the following statement is incorrect with reference to hydroallantois in cattle?
OPTIONS
(A) It occurs in 85% to 90% of cases of dropsy.
(B) Abdominal enlargement develops slowly over many months
(C) The foetus and placentomes cannot be palpated.
(D) The prognosis is extremely poor.
ANSWER
(B) Abdominal enlargement develops slowly over many months
EXPLANATION
Hydroallantois typically causes rapid abdominal enlargement over days to a few weeks, so slow enlargement over many months is the incorrect statement. It accounts for most bovine cases of excessive fetal-fluid accumulation and can make the fetus and placentomes difficult or impossible to palpate. Prognosis is often guarded to poor, particularly in severe cases. Gradual enlargement is more characteristic of hydramnios.
