Several imaging findings of thoracic diseases have been referred—on chest radiographs or CT scans—to signs, symbols, or naturalistic images. Most of these imaging findings include the air bronchogram sign, the air crescent sign, the arcade-like sign, the atoll sign, the cheerios sign, the crazy paving appearance, the comet-tail sign, the darkus bronchus sign, the doughnut sign, the pattern of eggshell calcifications, the feeding vessel sign, the finger-in-gloove sign, the galaxy sign, the ginkgo leaf sign, the Golden-S sign, the halo sign, the headcheese sign, the honeycombing appearance, the interface sign, the knuckle sign, the monod sign, the mosaic attenuation, the Oreo-cookie sign, the polo-mint sign, the presence of popcorn calcifications, the positive bronchus sign, the railway track appearance, the scimitar sign, the signet ring sign, the snowstorm sign, the sunburst sign, the tree-in-bud distribution, and the tram truck line appearance. These associations are very helpful for radiologists and non-radiologists and increase learning and assimilation of concepts.Therefore, the aim of this pictorial review is to highlight the main thoracic imaging findings that may be associated with signs, symbols, or naturalistic images: an “iconographic” glossary of terms used for thoracic imaging is reproduced—placing side by side radiological features and naturalistic figures, symbols, and schematic drawings.

Background: Background: Changes in the treatment landscape of CLL have complicated the decision-making processes, especially in the context of relapsed/refractory (R/R) disease. In this setting current guidelines do not provide clear information on the sequencing of targeted agents (TAs). Aims:Aims: With this in mind a series of evidence-based recommendations were produced to support pts, clinicians, and other health care professionals in their decisions about the management of R/R CLL. Methods:Methods: A multidisciplinary panel that included specialists in methodology, CLL management, and hematology, performed a systematic review of the literature using the databases MEDLINE, EMBASE, and the Cochrane Library, then participated in a virtual consensus conference held at the end of December 2021. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to formulate recommendations. Specifically, the strength of recommendations was determined by the balance between desirable and undesirable consequences of alternative management strategies, quality of evidence, variability in values, preferences, and resource used.

Background: Early interim-PET (PET-2) is the most powerful factor able to predict treatment outcome in advanced-stage Hodgkin Lymphoma (HL) patients treated with ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine). The 2-y PFS of PET-2 positive patients is only 12%, but the optimal treatment for this patient subset is still unknown. For this reason in January 2006 a treatment policy was designed by GITIL (Gruppo Italiano Terapie Innovative nei Linfomi) to early intensify chemotherapy with BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) for HL patients with a PET-2 positive after 2 ABVD cycles. Patients and methods: 136 HL patients with advanced-stage or intermediate-stage with adverse prognostic factors (more than 3 nodal sites, ESR > 50 mm, sub diaphragmatic presentation, bulky lesion), consecutively admitted to nine GITIL Italian centers were treated with two ABVD courses and re-evaluated with interim-PET. Twenty-one of these 136 patients proved to be PET-2 positive, and 19/21 are the object of this analysis. The mean age was 31.7 years (16–64), 10 patients were in stage II, 9 in stage III–IV. Bulky disease was present in 11, and B-symptoms in 16. Fourteen patients showed an IPS score 0–2, 5 patients a score 3–7. The median interval between the end of second ABVD course and PET-2 was 11 days (5–14). BEACOPP (4 escalated and 4 standard cycles) was followed by consolidation radiotherapy in 3 patients for bulky mediastinal tumor. PET scan were centrally reviewed by two well-experienced nuclear medicine experts, using the blood pool mediastinal structures (BPMS) as reference for the residual uptake, as elsewhere published (Gallamini, JCO 2007). Results. Upon central review, 2 interim-PET scan were classified as minimally positive in 2 patients, with a single MRU (Minimal Residual Uptake) lesion showing a SUV (Standardized Uptake Value) lower than BPMS, and therefore only 19 cases were suitable for the BEACOPP salvage treatment. After a mean follow-up of 14.3 months (7.0–30.2), 15 patients remain in continuous CR and 4 had a treatment failure because of disease relapse (1) or progression (3). For the responding patients the mean duration of CR was 13.0 months (6.5–30.2). The IPS score for progressing patients was 2, 3, and 4; for the relapsing-one, 0. At time of this analysis, l8 patients are still alive and 1 died during BEACOPP treatment for disease progression. The 1-year second treatment failure-free survival (1-y 2TFFS) was 94.7 % (95% C.I. 84.7–100). The 1 y OS survival was 93.3 (95%C.I. 80.7–100). In univariate analysis the only clinical factor related to treatment failure was the presence of extra-nodal disease. (Log-rank=6.8 p=0.009). Conclusions. BEACOPP-escalated regimen was able to induce durable CR in most (15/19) HL patients with a positive interim-PET. These results, although requiring a longer follow-up and a higher number of patients, seem to suggest that the very-poor prognosis of PET-2 positive, ABVD-treated HL patients can be substantially improved by early chemotherapy intensification; escalated-BEACOPP is likely to represent a good treatment choice for this very poor prognosis patient subset.
