Chronic esophageal dissection: Delayed diagnosis in a 15-year-old male.

Esophageal dissection is a rare condition, characterized by disruption of the submucosa from the muscular layer of the esophageal wall. It is commonly iatrogenic in etiology and patients typically present with acute onset dysphagia, odynophagia, and retrosternal pain. The condition can be diagnosed endoscopically; however, contrast swallow studies either with CT or fluoroscopy carry less risk and are the imaging investigations of choice for this condition.

Imaging of bone and soft tissue BCOR-rearranged sarcoma.

With recent advances in molecular research, an ever-increasing number of undifferentiated round cell sarcomas without the characteristic gene fusions of Ewing sarcoma are being discovered. One specific subtype termed BCOR-rearranged sarcoma belongs to this group. Previously termed 'Ewing-like' sarcoma, it was formally included with undifferentiated round cell tumours in the 2013 WHO Classification of Soft Tissue and Bone Tumours.

Insufficiency fractures: A rare cause of foot and ankle pain in three patients with rheumatoid arthritis.

Insufficiency fractures are recognized but rare complications in patients with longstanding rheumatoid arthritis. Such fractures are typically solitary and are rarely seen to affect the foot and ankle. We describe 3 women with longstanding rheumatoid arthritis, treated with one, or a combination of, corticosteroids, DMARDs and anti-TNF, presenting with foot and ankle pain with no prior history of trauma.
