Breast cancer is the most frequently diagnosed neoplasm in women in Italy. There are several risk factors, but thanks to screening and increased awareness, most breast cancers are diagnosed at an early stage when surgical treatment can most often be conservative and the adopted therapy is more effective. Regular screening is essential but advanced technology is needed to achieve quality diagnoses. Mammography is the gold standard for early detection of breast cancer. It is a specialized technique for detecting breast cancer and, thus, distinguishing normal tissue from cancerous breast tissue. Mammography techniques are based on physical principles: through the proper use of X-rays, the structures of different tissues can be observed. This first part of the paper attempts to explain the physical principles used in mammography. In particular, we will see how a mammogram is composed and what physical principles are used to obtain diagnostic images.

Breast cancer is the most common and most commonly diagnosed non-skin cancer in women. There are several risk factors related to habits and heredity, and screening is essential to reduce the incidence of mortality. Thanks to screening and increased awareness among women, most breast cancers are diagnosed at an early stage, increasing the chances of cure and survival. Regular screening is essential. Mammography is currently the gold standard for breast cancer diagnosis. In mammography, we can encounter problems with the sensitivity of the instrument; in fact, in the case of a high density of glands, the ability to detect small masses is reduced. In fact, in some cases, the lesion may not be particularly evident, it may be hidden, and it is possible to incur false negatives as partial details that may escape the radiologist’s eye. The problem is, therefore, substantial, and it makes sense to look for techniques that can increase the quality of diagnosis. In recent years, innovative techniques based on artificial intelligence have been used in this regard, which are able to see where the human eye cannot reach. In this paper, we can see the application of radiomics in mammography.

Fibromyalgia is a widespread condition which is currently underdiagnosed; therefore we conceived this study in order to assess whether a diagnostic suspicion may be assumed during widespread screening procedures, so that patients for which a reasonable diagnostic suspicion exist may be redirected towards rheumatologic evaluation. We analyzed a sample of 1060 patients, all of whom were female and undergoing standard breast cancer screening procedures, and proceeded to evaluate the level of pain they endured during mammographic exam. We also acquired a range of other information which we related to the level of pain endured; we suggested a rheumatologic examination for those patients who endured the highest level of pain and then we evaluated how many patients in this subgroup were actually diagnosed with fibromyalgia. Out of the 1060 patients who participated to our study, 139 presented level 4 pain intensity; One patient did not go for rheumatologic examination; the remaining 138 underwent rheumatologic evaluation, and 50 (36%, 28–44, 95% CI) were diagnosed with fibromyalgia. Our study shows that assessing the level of pain endured by patients during standard widespread screening procedures may be an effective asset in deciding whether or not to suggest specialist rheumatologic evaluation for fibromyalgia.

Introduction. Coronavirus SARS-CoV-2, the causative agent of COVID-19, primarily causes a respiratory tract infection that is not limited to respiratory distress syndrome, but it is also implicated in other body systems. Systemic complications were reported due to an exaggerated inflammatory response, which involves severe alveolar damage in the lungs and exacerbates the hypercoagulation that leads to venous thrombosis, ischemic attack, vascular dysfunction and infarction of visceral abdominal organs. Some complications are related to anticoagulant drugs that are administrated to stabilize hypercoagulability, but increase the risk of bleeding, hematoma and hemorrhage. The aim of this study is to report the diagnostic role of CT in the early diagnosis and management of patients with severe COVID-19 complications through the most interesting cases in our experience. Material and Methods. The retrospective analysis of patients studied for COVID-19 in our institution and hospitals, which are part of the university training network, was performed. Cases. Pneumomediastinum, cortical kidney necrosis, splenic infarction, cerebral ischemic stroke, thrombosis of the lower limb and hematomas are the most major complications that are reviewed in this study. Conclusions. Since the onset of the COVID-19 pandemic, the CT imaging modality with its high sensitivity and specificity remains the preferred imaging choice to diagnose early the different complications associated with COVID-19, such as thrombosis, ischemic stroke, infarction and pneumomediastinum, and their management, which significantly improved the outcomes.

Inferior vena cava leiomyosarcoma is a rare malignant mesenchymal tumor that originates from the smooth muscle cells of the venous media and is more frequent in females in the V-VI decade of life. Due to scarce and specific symptoms, diagnosis is not simple, and often metastases to the liver, lungs, and/or lymph nodes are already present. A 44-year-old male patient arrives at our institution presenting diffuse abdominal pain and a sense of weight associated with lumbar pain. He showed nothing relevant except for a moderate consumption of alcohol. Ultrasound examination of the abdomen revealed liver enlargement with hyperechoic nodularity and clear margins. Furthermore, the presence of a voluminous solid nodular formation was found, with an inhomogeneous echostructure and moderate vascularization on Doppler. Inferior vena cava leiomyosarcoma is a rare malignancy. The diagnosis is usually established after surgery, however, recurrences are common and the role of chemoradiation therapy remains to be defined. The only potential treatment is surgical resection with possible vessel reconstruction and en bloc removal of adjacent structures with 5 and 10-year survival rates of 49% and 29%, respectively.

Liposarcoma of the spermatic cord is a malignant neoformation so rare that less than 200 cases are reported in the world. It is a tumor that originates from adipose tissue and when it is found in the spermatic cord it can deceptively simulate an inguinal hernia and not be easily identified. The present work describes the case of a 37-year-old man with liposarcoma of the spermatic cord who arrives at our institution with painless swelling of the left testicle. Physical examination revealed a painless swelling in the scrotal sac. The scrotal ultrasound examination revealed a mass, measuring 8 cm (cranio-caudal) × 5.4 cm (latero-lateral) × 8 cm (antero-posterior) and characterized later with a basal CT examination of the abdomen. The patient was subsequently surgically treated with excision of the tumor, plus hernial plastic with plug and mesh. Histological examination revealed a mature adipocyte neoplasm whose morphological and molecular characteristics (amplification of the MDM2 gene) are consistent with the diagnosis of dediferrentiated liposarcoma variety CO-MINGLED, G2 (sec. FNCLCC). The patient is currently under cancer surveillance with no signs of loco-regional recurrence. Spermatic cord liposarcoma is an extremely rare malignancy. It's not easy to identify as it can simulate an inguinal hernia, hydrocele, lipoma, funicular cyst, or testicular tumor. Diagnosis is usually established postsurgery, however, relapses are common and the role of chemo-radiotherapy remains to be defined.
