Dear Friends,

      right pleural effusion with multiple enhancing pleural nodules.
      no suggestive signs of TB.
      the age and appearance don`t suggest mesothelioma, although can`t be excluded.
      in this age and with this appearance i think the probable diagnosis is metastatic disease (osteosarcoma?..).

      • tr says:

        a hypodense lesion in the right hilum, seen in the lower CT image, might be the primary source of metastases.

    2. Ren says:

      There is right pleural effusion with nodular pleural lesions along the mediastinal and costal pleura. Thickening of the right minor fissure noted without nodularity.The morphology of the lesion is not very specific for malignancy and in a young patient with fever infection cannot be excluded. So I think any of the above could be possible. Pleural fluid analysis and biopsy should be suggested. Thank you.

      The air that is under the left diaphgram… is it on the Stomach?
      Mtx from a carcinoid perhaps?

        In the PA x-ray there are some apical extrapulmonary lesions and in the right paratracheal margin, probably more pleural lesions.

      -Right pleural effusion + enhancing nodular pleural thickening.

      Possible diagnosis: pleural tumor (mesothelioma, lymphoma), metastases.

    8. Olena says:

      Right massive pleural effusion with multiple nodules localized on visceral pleura of the posterior and right lateral chest wall, on the diaphragmal pleura and also on mediastinal pleura, growing in pericardium (?) some of them have smooth well-defined and other on the contrary ill-defined and irregular contours, and also some of them have small region of hypointensity

      Really very nice and comlicated case. Only one-sided type of changes, chest pain but no fever make to suggest firstly malignancy/mts. however if to suggest tuberculosis – it is not typical for such tuberculosis changes to be without fever, only with chest pain.

      The anamnesis is also a pitfall – Venezuela it is exotic country so any other rare diseases can differentiated(parazites, infections)

      If to take in consideration the x-ray images some peribronchial changes are seen predominantly in midddle zones and on the right and pleural plaques are also seen on the right apex.

      nice case…
