Idiopathic intracranial hypertension: Imaging and clinical fundamentals

Figure 16  The “STOP” acronym for idiopathic intracranial hypertension. We have fabricated the “STOP” acronym for idiopathic intracranial hypertension (IIH) merely as a mnemonic tool. Although there are several signs that may be encountered in IIH cases, the presence of 3 out of 4 of these signs mentioned above may suggest (but not verify) the probability of IIH diagnosis in specific clinical scenarios according to the revised IIH criteria (Friedman et al[1], 2013). Therefore, specifically assessing these neuroimaging signs and addressing their presence or absence in the radiological report may be of increased value for the referring physician.
