Studies indicated that malignancy developed more frequently in medical thoracoscopy (MT) than in VATS in the follow-up period of patients with nonspecific pleuritis in long-term outcome.12,13,18 Mesothelioma is the most common malignancy in these patients.21 In patients with pleural adhesions and/or fibrinous
layer on the pleura, inadequate examination of the pleural cavity and difficulty in accessing the neoplastic tissue reduce the diagnostic success of MT, and VATS is recommended in such patients.22 VATS is performed under general anaesthesia in a lateral decubitus position.
Most sick birds were diagnosed with septicemia, occasionally with fibrinous
exudation into the coelomic cavities.
Histologically, the excised lobe was effaced by severe necrosuppurative pneumonia with hemorrhage and fibrinous
pleuritis but no intralesional bacteria (Figure 2).
The histological observation revealed that in Group B the whole wound was covered with thin layer of stratified squamous epithelium on day 7 with very little or without fibrinous
The signs are more than the symptoms and sometimes endothelial plaques are seen and the hypopyon is thick fibrinous
and the upper level is irregular.
Patients with posterior synechia, hypopyon, and/or fibrinous
reaction in the anterior chamber were recorded separately.
The classification also described the provisional criteria of 2 rare histologic patterns: acute fibrinous
and organizing pneumonia (AFOP) and bronchiolocentric patterns of interstitial pneumonia (BPIP).
When the process is prolonged, fibrinous
material spreads through necrotic cartilage to the synovial space, tendon sheath, and bursae.
Briefly: 1) Peracute fibrinous/ necrotizing pneumonia (pleuropneumonia): extensive dissemination; associated with blood tinged fluid in the pleural cavity; extensive fibrinous
pleuritis, 2) Acute/subacute fibrinous/necrotizing pneumonia (pleuropneumonia): predominantly caudodorsal; fibrinous
pleuritis and 3) Chronic necrotizing pneumonia (pleuropneumonia): predominantly caudodorsal; firm capsulated processes with necrosis and abscesses; local fibrous pleuritis (S0RENSON et al., 2006).
Setarial parasites are commonly found in peritoneal cavity of ungulates and adults in peritoneal cavity are generally non-pathogenic but may be associated with mild fibrinous
peritonitis (Constable et al., 2017).
Libman-Sacks endocarditis (LSE) is sterile fibrinous
vegetation that preferentially develops at the left-sided heart valves.
The first type of reaction is aseptic fibrinous
reaction in which the adhesion and encapsulation results in a granuloma formation and remain asymptomatic for a long time (3-5).
