| Sometimes the first manifestation is a hydrops and a fluctuating swelling in the upper part of scarpa's triangle. |
| The rapidity with which emaciation, hydrops, and marasmus occur in severe cases is thus easily accounted for. |
| Occasionally a constriction occludes the course of the tube, while the distal end is dilated into a condition of hydrops. |
| If susceptibility or recent infection is indicated by serology, weekly ultrasound examinations should be performed for four to eight weeks after exposure to detect hydrops. |
| The capsular ligament, except in hydrops, is the seat of connective-tissue overgrowth, and tends to become contracted and rigid. |
| When the affection is of long standing and the joint is much distended it may be termed hydrops articuli or hydrarthrosis. |
