Pleural thickening or nodule [greater than or equal to] 1 cm, lung mass [greater than or equal to] 1 cm, abdominal mass, liver metastasis, absence of pleural
loculation, pericardial effusion or cardiomegaly all were positively associated with a malignant aetiology.
We are most pleased to be working with our expert partners at ABL to move this new NIH SMARTT project forward, and hope it will be a key step that will introduce new and better therapy for pleural
loculation into clinical practice.
Loculation of pericardial infection in the form of an abscess is rare.
These lesions have an outer zone of granulation tissue and a central purulent
loculation surrounding the Actinomyces colonies.
However, even 2-3 weeks after symptom onset, a CT scan may show evidence of early organization and
loculation of peripancreatic fluid that may indicate a gathering infection.
Therefore,
loculation of the radioactive tracer within an abdominal collection suggests pseudocyst formation.
Cyst formation may be the result of hemorrhage or necrosis, fluid secretion from the meningioma, or
loculation of cerebrospinal fluid (CSF).
Tuberculosis can also be considered when the omental cake occurs in conjunction with other imaging features, such as ascites with adhesions/septations and
loculation, peritoneal and mesenteric thickening, bowel wall thickening, lymphadenopathy, and stigmata of TB in the chest.
Additional pleural CT appearance features such as
loculation, pleural thickening and nodules are not reliable in differentiating exudates from tansudates, although their prevalence is higher among exudative effusion.
8 cm in size with evidence of peripheral wall calcification and
loculation extending from pelvis to epigastrium.

Open drainage allow complete evacuation of pleural fluid by debridement and disruption of all
loculations which is necessary for full lung expansion and resolution of infection.
