“…Its usefulness was first documented in lung cancer, but it is now also one of the imaging tools for pleural diseases [4,5,6,7]. However, a major drawback with FDG-PET is that any kind of inflammation can produce high uptake values in almost any tissue.…”

The FDG-PET (fluorine-18 fluorodeoxyglucose positron emission tomography) scan is used with increasing frequency to investigate pleural abnormalities and to determine the possibility of neoplastic invasion. However, false-positive findings are not uncommon and talc pleurodesis has been reported to cause hypermetabolic pleural thickenings up to 5 years after the procedure. We report the cases of 3 patients (2 of whom had a history of asbestos exposure) requiring talc pleurodesis for recurrent pneumothoraces between 1988 and 1990, who were investigated in 2011 for pleural abnormalities. Avid pleural thickening on FDG-PET scan mimicking pleural cancer was found, but this was deemed secondary to the pleurodesis. Talc pleurodesis generates inflammation which promotes pleural adhesions. This inflammatory reaction could decrease with time, as in other inflammatory processes. Since talc is not metabolized by the body, the FDG-PET scan can remain positive, most likely because of a foreign-body granulomatous reaction, even 20 years later. It is important to be aware of this possibility and to question patients with pleural abnormalities about past procedures and mention such procedures to the colleagues who are responsible for interpreting metabolic imaging. Follow-up of hypermetabolic pleural lesions attributed to talc pleurodesis is important for the detection of new pleural lesions or neoplastic evolution.

“…In clinical routine, the decision whether to perform pleurocentesis in a patient is usually based on the clinical findings and the visual estimation of the pleural effusions on chest X-ray, ultrasound, or CT scans (13). However, the precise volumetry of pleural effusions remains challenging, particularly in patients with loculated effusions and atelectasis.…”

“…Additionally, some sources suggest the use of fat-saturated T1 MRI [ 8 , 17 ]. T1 images provide a contrast between the pleural abnormalities and the extra-pleural fat [ 74 ], while T2 images can be used to obtain tissue-specific data [ 74 ]. PDW (proton density-weighted) MRI and T2 MRI were found to be useful for differentiating between the malignant and benign pleural conditions [ 8 ].…”

“…It tracks the signal changes after a passage of an administered contrast agent through rapid sequential imaging [ 10 , 108 ]. DCE could be used to assess the vascularity, perfusion, and vascular permeability of the pleural malignancies and predict their response to chemotherapy [ 1 , 11 , 16 , 17 , 74 , 75 , 82 , 107 , 108 , 112 , 115 , 116 , 117 ]. A two-compartment mathematical model may be used for pharmacokinetic analysis, to quantify the changes in microcirculation and judge vascular permeability [ 10 , 82 ].…”

The primary pleural neoplasms constitute around 10% of the pleural tumors. The currently recommended method for their imaging is CT which has been shown to have certain limitations. Strong development of the MRI within the last two decades has provided us with a number of sequences that could potentially be superior to CT when it comes to the pleural malignancies’ detection and characterization. This literature review discusses the possible applications of the MRI as a diagnostic tool in patients with pleural neoplasms. Although selected MRI techniques have been shown to have a number of advantages over CT, further research is required in order to confirm the obtained results, broaden our knowledge on the topic, and pinpoint the sequences most optimal for pleural imaging, as well as the best methods for reading and analysis of the obtained data.
