Spontaneous perforation of pyometra: A rare cause of acute abdomen and sepsis.

Pyometra, the accumulation of purulent material in the uterine cavity, is a rare gynecological condition whose etiology is impaired drainage of the uterine cavity. It is uncommon in premenopausal age and occurs mainly in older and postmenopausal women. Clinical signs of pyometra are vaginal discharge, postmenopausal bleeding, and lower abdominal pain.

A critical overview of the imaging arm of the ASAS criteria for diagnosing axial spondyloarthritis: what the radiologist should know.

The Assessment in SpondyloArthritis international Society (ASAS) defined new criteria in 2009 for the classification of axial spondyloarthritis (SpA) in patients with ≥ 3 months of back pain who were aged <45 years at the onset of back pain. This represents a culmination of a number of efforts in the last 30 years starting with the 1984 modified New York criteria for ankylosing spondylitis, followed by the 1990 Amor criteria and the 1991 European Spondyloarthropathy Study Group criteria for SpA. The importance of new ASAS criteria for radiologists is that magnetic resonance imaging (MRI) takes center stage and is one of the major criteria for the diagnosis of axial SpA when active (or acute) inflammation is present on MRI that is highly suggestive of sacroiliitis associated with SpA.
