Nephrogenic systemic fibrosis
Nephrogenic systemic fibrosis (NSF), also known as nephrogenic fibrosing dermopathy, is a complication of gadolinium-based contrast agents used in imaging studies. It is characterised by "firm, erythematous, and indurated plaques of the skin associated with subcutaneous oedema" 1. Eventually, f...
Scaphoid fractures (i.e. fractures through the scaphoid bone) are common, in some instances can be difficult to diagnose, and can result in significant functional impairment. Epidemiology Scaphoid fractures account for 70-80% of all carpal bone fractures 1. Although they occur essentially at a...
AAST spleen injury scale
The 2018 revision of the American Association for the Surgery of Trauma (AAST) splenic injury scale is currently the most widely used grading system for splenic trauma. The following is the imaging criteria for classification based on CT findings. Classification grade I subcapsular haematoma ...
Subarachnoid haemorrhage (SAH) is one of the types of extra-axial intracranial haemorrhage and denotes the presence of blood within the subarachnoid space. Epidemiology Patients tend to be older middle age, typically less than 60 years old 2. Subarachnoid haemorrhage accounts for 3% of stroke ...

An intracerebral haemorrhage, or intraparenchymal cerebral haemorrhage, is a subset of an intracranial haemorrhage. This can encompass a number of entities that share the acute accumulation of blood in the parenchyma of the brain. The aetiology, epidemiology, treatment and prognosis vary widely ...
A perforated appendix is one of the complications of acute appendicitis. If appendicitis is left untreated, ischaemic necrosis of a portion of appendiceal wall may occur, leading to perforation. An appendicolith is thought to be associated with a higher probability of perforation 1. Epidemiolog...
Sigmoid volvulus is a cause of large bowel obstruction and occurs when the sigmoid colon twists on its mesentery, the sigmoid mesocolon. Epidemiology Large bowel volvulus accounts for ~5% of all large bowel obstructions, with ~60% of intestinal volvulus involving the sigmoid colon 6. It is mor...
