Case Reports
MR imaging of acute intermittent porphyria mimicking reversible posterior leukoencephalopathy syndrome.
Reversible posterior leukoencephalopathy syndrome (PLS) is characterized by headache, altered mental function, visual disturbances and seizures. Neuroimaging studies suggest a white-matter oedema, predominantly in the posterior parietal-temporal-occipital regions of the brain. We present the case of a 30-year-old woman who had suffered her first attack of acute intermittent porphyria (AIP). ⋯ Following treatment with haematin and a high carbohydrate diet the patient's condition improved. Follow-up magnetic resonance imaging (MRI) revealed complete resolution of the lesions. To our knowledge, this is the first report concerning a completely reversible PLS in AIP.

Case Reports
Inflammation of vertebral bone associated with acute calcific tendinitis of the longus colli muscle.
We present a case of acute retropharyngeal calcific tendinitis with characteristic findings on radiographic, computed tomography, and magnetic resonance imaging (MRI). To our knowledge, this is the first acute retropharyngeal calcific tendinitis report having inflammation of both the vertebra itself and the longus colli muscle diagnosed on MRI. In patients with neck pain, acute retropharyngeal calcific tendinitis should be kept in mind in the differential diagnosis, even if these patients had vertebral pathological signals on MRI.
