Same patient.
Puncture.
It is implemented in the prone position. We see the image turned in a supine position. The direction of the needle avoids the large vessels. It reveals protein-rich fluid, the bacteriology is negative.
Take-home message:
imaging gives no answer on persisting effusions bacteriology. Despite decades of sterility, it can be suddenly infectiously activated without giving a morphological hint.
New patient 47:
51 years ago, in 1958, this case was published in "Tuberkulose Arzt”. The author, HG Schmitt, would be 102 years old. He had first seen the patient in 1944; it was then that his interest for pleural pathology commenced:
our patient is a 38-year old man who had prolonged pleurisy in 1958, 16 years prior to the admission. The overview x-ray (in low KV-technique) shows no calcification.
One suspected a neoplastic mass. Your answer is right. – The next picture shows a simple method which gives new information.
120 kV and Bucky-Potter grid demonstrate a large, homogenous, globular shadow enveloped by a calcified shell .
Sonography and CT. Both did not exist at that time. It would verify a chronic, persistent effusion bordered by calcified visceral and parietal pleura.
Note the uncalcified layer between parietal pleura and the inner thoracic wall. -
In 1953 they performed the following exam:
A conventional axial tomography.
Spine, aorta descendens, heart shadow and the voluminous persistent effusion, which is surrounded by a calcified layer.
Radiograph of the operative specimen, demonstrating the envelope of irregular calcified connective tissue.
