A severe presentation of breakthrough infection caused by the Omicron variant with radiological findings of COVID-19 pneumonia in an elderly woman.

Omicron variant of COVID-19 is characterized by exceptional transmissibility and by immune evasion with the ability infect people with naturally acquired or vaccine-induced immunity. However, lung involvement is poorly reported in patients who resulted positive by this new COVID-19 variant. COVID-19 breakthrough infections are defined as COVID-19 infection in fully vaccinated patients.

Unusual presentations of COVID-19 pneumonia on CT scans with spontaneous pneumomediastinum and loculated pneumothorax: A report of two cases and a review of the literature.

Spontaneous pneumomediastinum (SPM) and Loculated pneumothorax (LPNX) are both generally rare clinical and radiological conditions associated with Coronavirus Disease 2019 (COVID-19). We report for the first time clinical data and radiological chest CT imaging of two patients affected by COVID-pneumonia associated with early radiological findings of SPM and LPNX.

Validation of DWI in assessment of radiotreated bone metastases in elderly patients.

Bone metastases are commonly observed in oncologic patients with advanced disease. These metastases are considered the main cause of neoplastic pain, with more than half of oncologic patients experiencing neoplastic pain during the course of the disease due to bone involvement. Lung, breast, and prostate cancers are the primary causes of bone metastases.

Performance status versus anatomical recovery in metastatic disease: The role of palliative radiation treatment.

Metastatic disease is a common complication of the most advanced malignancies. It may compromise the patients' quality of life, often posing a greater risk than the primary disease itself. Currently, several different therapeutic approaches are available to palliate or cure (single metastasis with primary neoplasm under control - radical surgery) secondary disease.

Sharp penetrating wounds: spectrum of imaging findings and legal aspects in the emergency setting.

The main cause of severe civilian trauma is not the same all over the world; while in Europe the majority of cases are due to blunt traumatic injury, in the United States, penetrating gunshot wounds are the most common. Penetrating wounds can be classified into two different entities: gunshot wounds, or more technically ballistic traumas, and sharp penetrating traumas, also identifiable with non-ballistic traumas. Sharp penetrating injuries are mainly caused by sharp pointed objects such as spears, nails, daggers, knives, and arrows.
