High Plasma Osteopontin Levels Are Associated with Serious Post-Acute-COVID-19-Related Dyspnea.

COVID-19 survivors commonly report persistent symptoms. In this observational study, we investigated the link between osteopontin (OPN) and post-acute COVID-19 symptoms and lung functional/imaging abnormalities. We recorded symptoms and lung imaging/functional data from previously hospitalized COVID-19 patients, who were followed for 4-84 weeks (122 patients/181 visits) post-symptom onset at our outpatient clinic.

Spontaneous Uterine Leiomyoma Torsion: A Challenging Differential Diagnosis for Radiologists.

Unlabelled: Uterine leiomyomas are very common gynaecological benign tumours. Spontaneous torsion of a uterine subserosal leiomyoma is a rare cause of acute lower abdominal pain and should be treated immediately with surgery. We report a case of an enlarged subserosal leiomyoma that was first detected by computed tomography (CT) and further confirmed by laparoscopic surgery to be a subserosal leiomyoma with torsion.

Haemoperitoneum Due to Spontaneous Rupture of a Liver Metastasis.

Unlabelled: Spontaneous rupture of a liver metastasis is a life-threatening complication of metastatic liver disease. Although metastatic liver lesions are much more common than primary tumours, spontaneous rupture of a liver metastasis is rare. Therapeutic decisions must take into account the extent of metastatic liver disease and the patient's performance status.

Contrast enhanced ultrasound of the kidneys: what is it capable of?

One of the many imaging uses of contrast enhanced ultrasound (CEUS) is studying a wide variety of kidney pathology, due to its ability to detect microvascular blood flow in real time without affecting renal function. CEUS enables dynamic assessment and quantification of microvascularisation up to capillary perfusion. The objective of this paper is to briefly refresh basic knowledge of ultrasound (US) contrast agents' physical properties, to study technical details of CEUS scanning in the kidneys, and to review the commonest renal indications for CEUS, with imaging examples in comparison to baseline unenhanced US and computed tomography when performed.

Massive intraperitoneal bleeding due to hemorrhagic cholecystitis and gallbladder rupture: CT findings.

Hemorrhagic cholecystitis with subsequent gallbladder rupture and torrential bleeding is a very rare but life-threatening complication of acute biliary tract diseases. Its clinical presentation may be dubious and therefore Computed Tomography (CT) imaging plays a crucial role in a prompt and accurate diagnosis. We present a case of a 64 year-old male who was admitted to the emergency department with clinical findings of acute cholecystitis.

Pancreatic sarcoidosis: MRI features.

Pancreatic sarcoidosis is a rare entity, and few reports in the literature describe the CT aspects of the disease. We report the MR features of a pathologically-confirmed case of pancreatic sarcoidosis, which presented as multiple pancreatic masses with low signal intensity on T1-weighted images, mild high signal intensity on T2-weighted images, and decreased enhancement compared to the normal pancreas after administration of gadolinium. Pancreatic sarcoidosis should therefore be included in the differential diagnosis of multiple pancreatic masses with these MRI features.
