Secondary extra-articular synovial osteochondromatosis with involvement of the leg, ankle and foot. An exceptional case.

Extraarticular synovial osteochondromatosis is a very rare benign disease whose aetiology may be primary or secondary to pre-existing pathology or after trauma. The diagnosis can be made with plain radiography and CT, and MRI is necessary to evaluate the non-mineralized soft tissue component and assess extension. It must be confirmed with a pathological study by biopsy or resection.

Pneumatosis intestinalis as an incidental finding in a patient with COVID-19 infection.

In reference to the article by Láinez Ramos-Bossini AJ et al., recently published in your Journal, we would like to provide our experience regarding a probable causal association between pneumoperitoneum and pneumatosis intestinalis in patients affected by COVID-19 (1).

Acute cholangitis in the context of Lemmel syndrome with signs of diverticulitis.

Here, we present the case of a 51-year-old male with pain in the right hypochondrium, jaundice, fever, chills and septic shock. A computed tomography (CT) scan showed a juxtapapillary diverticulum with inflammatory changes, which caused bile duct ectasia and left biliary radicals. We considered this to be a septic shock of a biliary origin due to the cholangitis associated with Lemmel syndrome, with signs of juxtapapillary diverticulitis.

Atraumatic splenic rupture as a complication of acute exacerbation of chronic pancreatitis, an unusual disease.

We report the case of a patient with acute exacerbation of chronic pancreatitis and he suffered an atraumatic splenic rupture. Splenic rupture not associated with trauma is a rare entity that can occurs in normal spleen (spontaneous) or damaged spleen (pathological). This entity may be associated with local inflammatory processes, such as pancreatitis.

Classifying thoracolumbar fractures: role of quantitative imaging.

This article describes different types of vertebral fractures that affect the thoracolumbar spine and the most relevant contributions of the different classification systems to vertebral fracture management. The vertebral fractures types are based on the three columns model of Denis that includes compression, burst, flexion-distraction and fracture-dislocation types. The most recent classifications systems of these types of fractures are reviewed, including the Thoracolumbar Injury Classification and Severity score (TLICS) and the Arbeitsgemeinschaft für Osteosynthesefragen Spine Thoracolumbar Injury Classification and Severity score (AOSpine-TLICS).
