Predictors of the presence of radiological abnormalities 6 months after severe COVID-19 pneumonia.

Background: SARS-CoV-2 pneumonia can cause significant long-term radiological changes, even resembling pulmonary fibrosis. However, the risk factors for these long-term effects are unknown. This study aims to assess radiological abnormalities and their possible risk factors six months after hospital discharge due to COVID-19 pneumonia.

Beyond Benign: A Case of Subependymal Giant Cell Astrocytomas Provoking Hydrocephalus in Tuberous Sclerosis Complex.

22-year-old male diagnosed with Tuberous Sclerosis Complex (TSC), a genetic disorder characterized by benign tumors in various organs, with a focus on neurological implications. Central to the study is the development of Subependymal Giant Cell Astrocytomas (SEGAs), leading to hydrocephalus in the patient. The diagnosis of TSC was made in the patient's childhood, and he was monitored regularly.

Publications on COVID-19 in radiology journals in 2020 and 2021: bibliometric citation and co-citation network analysis.

Objectives: The pandemic caused by SARS-CoV-2 has led to the rapid publication of numerous radiology articles, primarily focused on disease diagnosis. The objective of this study is to analyze the intellectual structure of radiology research on COVID-19 using a citation and co-citation analysis.

Methods: We identified all documents about COVID-19 published in radiology journals included in the Web of Science in the period 2020-2021, conducting a citation analysis.

Primary neuroendocrine tumour of the kidney in an asymptomatic patient involving a multidisciplinary approach.

Primary neuroendocrine tumours of the kidney are rare, and their pathophysiology is uncertain; since their discovery in 1966, they have been described only a few times in the literature. We present a case of a well-differentiated neuroendocrine tumour of the kidney in an asymptomatic patient, which required a multidisciplinary approach by the hospital's team, including precise surgical treatment and an effective radiopathological diagnosis. The patient underwent right radical nephrectomy.

Unusual Presentation of a Posterior Reversible Encephalopathy Syndrome With Brainstem Involvement and Subarachnoid Haemorrhage.

Posterior reversible encephalopathy syndrome is an increasingly recognized disorder characterized by a headache, visual disturbances, and seizures. It is a reversible neurotoxic state, with multiple risk factors in which endothelial injury and compromised brain perfusion are the common characteristics. Diagnosis is usually made by cerebral magnetic resonance imaging that typically shows early-stage bilateral symmetrical parieto-occipital hyperintensities on T2 and fluid-attenuated inversion recovery (FLAIR) sequences.

Primary Malignant Melanoma of the Esophagus: A Case Report and Review of the Literature.

BACKGROUND Primary malignant melanoma of the esophagus (PMME) is a rare cancer with a poor prognosis. It is often difficult to differentiate from non-epithelial malignant tumors, and immunohistochemical staining may be needed to diagnose the condition. The mainstay of treatment is usually surgical with curative or palliative intent, since radio- and chemotherapy do not really improve the outcome.
