Methods and materials
Chest CT imaging findings of 30 cases of patologically proven PPL were reviewed retrospectively,
in the period between 2002 and 2017.
Histology was confirmed by lung biopsy.
Patients
Patients were 14 males and 16 females (aged 58-86,
mean age 72 years).
PPL subtypes were MALT lymphoma (N=23,
76.6%) and DLBCL (N=7,
23.4%).
CT examinations and images interpretation
CT exams were performed at baseline and after contrast medium administration (arterious and venous phase).
The acquisitions were all in inspiration phases and high resolution images were contiguously reconstructed at 1-1.25 mm using standard filtered back-projection,
a smooth reconstruction kernel (B30f) for mediastinal structures and a sharp one (B70f) for parenchymal evaluation.
All the staging CT scans were evaluated by two expert radiologists in order to radiologically define the predominant pattern of presentation.
CT were assessed for the presence of:
- pulmonary nodules (single/multiple,
diameter <2.5 cm)
- masses or mass-like consolidations (diameter >2.5 cm) with or without the coexistence of a positive angiogram-sign
- ground glass opacities
- parenchymal distribution (bronchovascular or perilymphatic spread)
- hilar lymphnodes (long axis >1.5 cm)
- pleura/chest wall involvement
