ABSTRACT
Lemierre's syndrome is characterized by anaerobic bacterial infection in the head and neck, causing thrombophlebitis of the jugular vein. This disease is usually associated with a history of pharyngitis. The most common pathogens are Fusobacterium species, particularly Fusobacterium necrophorum. Lemierre's syndrome is seen most commonly in teenagers and young adults. We present a case report of a 67-year-old man with an atypical clinical manifestation of an uncommon pathogen in Lemierre's syndrome with epilepsia partialis continua.

A hyperintensity in the subarachnoid space on fluid-attenuated inversion-recovery (FLAIR) images is often caused by diseases such as subarachnoid hemorrhage or meningitis. Oxygen has a known paramagnetic effect and also causes signal changes in the subarachnoid space on FLAIR images. These changes usually develop when the inspired air contains a high oxygen fraction. Here we present a patient with a hyperintensity in the subarachnoid space on FLAIR images whose inspired air contained only a low oxygen fraction.

Reversible splenial lesion may occur in encephalitis rarely. A 21-year-old man was admitted with viral encephalitis. High signal on the diffusion MRI and low signal on the ADC map image was showed in the splenium. As the patient improved, the lesion suggestive of cytotoxic edema was completely resolved one month later. Although the concrete pathophysiology of focal cytotoxic edema in encephalitis is unclear yet, MRI is valuable diagnostic tool to manage encephalitis in the view of prognosis.
