Examples of pleural

• Effusions may also be related to the amount of pleural surface area supplied by collateral vessels.

• Finally, the shape of the posterior pleural field, deeper in front and merging with the border behind, is narrower behind.

• The method has now been extended for drainage of pleural effusions of varied aetiologies, and even pneumothorax in small patients, with the same favourable results.

• Prosopon on borders and spines consists of dense concentration of relatively fine tubercles; small number of larger tubercles scattered on pleural ridges and major spines.

• Two patients had bilateral pleural effusions that resolved during the in-hospital period and one a left pneumothorax without consequences.

• The thorax is narrow and tapers posteriorly, the pleural spines of the last segment being long and directed backwards.

• The body cavities (peritoneal and pleural), lungs, liver, heart and spleen were checked for metacestodes.

• It is supposed that schistosomula escape from pulmonary capillaries into alveoli and migrate through pulmonary tissues to the pleural cavity.
