Plain radiographs (4-view scaphoid series) is used for diagnosis. However, scaphoid fractures may be occult and the risk of avascular necrosis merits follow-up in patients with continued symptoms.. Additional follow-up in this group can make use of a bone scan or MRI because of their greater sensitivity and specificity. ...

Atresia (plural: atresias) refers to a situation where there is absence, underdevelopment or abnormal closure, of a normal anatomical tubular structure or opening. Contrast this with agenesis which refers to the complete absence of any anatomical structure including its primordial precursors.. For example:. ...

Edge of film errors, also known as corner of film errors, are a classical perceptual error in radiology where a pertinent finding, whether incidental or not, is at the margin or edge of the image.. It is now used for all modalities, in both a literal sense, i.e. actually at the edge of the image, or more metaphorically, perhaps just the last slice in an image series or only seen on a single MRI localizer image.. Under the Renfrew classification of errors in radiology, these errors are generally thought to be "type 4: under-reading", although it could also be argued that in some cases they are also "type 9: location", i.e. outside the area of interest 3.. ...

Hickams dictum is usually stated as "patients can have as many diseases as they damn (or darn) well please". This aphorism has been attributed to John Hickam (1914-1970) an American physician, who was Chair of the Department of Medicine at the University of Indiana 1. The importance of this dictum lies in it acting as a counterweight to Occams razor, declaring that a patients clinical presentation may be secondary to two or more pathologies, rather than the parsimony of a single condition explaining all the symptoms and signs as put forward in the eponymous razor. Indeed in many cases it is more probable that an individual has multiple morbidities underlying the presentation, instead of one unifying diagnosis.. Hickams dictum has also been expressed in a slightly different way as Saints triad.. References 2 and 3 below nicely illustrate the tensions between Hickams dictum and Occams razor in modern medicine 2,3. ...

Butterfly gliomas are high-grade astrocytomas, IDH-mutant or glioblastomas, IDH-wildtype that cross the midline via the corpus callosum. Other white matter commissures are also occasionally involved. The term butterfly refers to the symmetric wing-like extensions across the midline. Butterfly gliomas most frequently occur in the frontal lobes, crossing via the genu of the corpus callosum, however, posterior butterfly gliomas are also encountered. ...

The metaphyses (singular: metaphysis) are the wide portions of long bones and the regions of the bone where growth occurs. Growth occurs at the section of the metaphysis that is adjacent to the growth plate (physis).. The metaphysis is located between the diaphysis and epiphysis.. A relatively rich blood supply and increased vascular stasis makes the metaphysis prone to hematogenous spread of infection in childhood and osteomyelitis. ...

By contrast, the ischemic penumbra will have only moderately decreased cerebral blood flow and normal or even increased cerebral blood volume due to autoregulation. It is of note that CT perfusion may overestimate infarct core on admission, especially in the early time window of a stroke, by predicting lesion in areas that will not show infarct on follow-up imaging, a phenomenon known as a ghost infarct core 3. ...
