We report the MRI findings in an adult with epiglottitis. There was thickening of the epiglottis and left aryepiglottic fold. Management of this life-threatening condition requires imaging only when the diagnosis is uncertain or when an abscess or other complication is suspected.

Case Reports
Delayed oedema in the pyramidal tracts remote from intracerebral missile path following gunshot injury.
A 60-year-old man developed a severe left hemiparesis and central facial palsy, accompanied by somnolence and dysarthria 9 days after a gunshot wound to the right temporal region, from which he slowly recovered over 3 months. MRI disclosed bilateral oedema of the pyramidal tracts. This was interpreted as a consequence of the impact of the pressure wave caused by the bullet, after excluding an infectious or vascular cause.

Racemose cysticercal cyst is the subarachnoid manifestation of the larvae of Taenia solium. On MRI the cysts may resemble other cystic masses. We report the magnetic resonance spectroscopy (MRS) features of a case on in vivo proton spectroscopy and discuss its role in the diagnosis of intracranial cysts of parasitic aetiology.

Central pontine myelinolysis (CPM) is one of the serious neurological complications of alcoholism. This study evaluated magnetic resonance images of sequelae of CPM. ⋯ In 3 of the 11 patients bilateral symmetrical oval lesions were faintly visible in the middle cerebellar peduncles. These middle cerebellar peduncular lesions were diagnosed as having Wallerian degeneration of the pontocerebellar tract secondary to CPM.

Review Case Reports
Giant spinal perimedullary fistula in hereditary haemorrhagic telangiectasia: diagnosis, endovascular treatment and review of the literature.
Hereditary hemorrhagic telangiectasia (HHT, Rendu-Osler-Weber disease) is a vascular disorder with dominant autosomal transmission characterised usually by multiple mucocutaneous and visceral abnormalities. Neurological manifestations due to the primary involvement of spinal cord by vascular malformations are rare. We present a young man with HHT associated with a central nervous system arteriovenous malformation and a giant perimedullary fistula, that was manifested as progressive myelopathy. ⋯ The therapeutic option was endovascular treatment by mechanically detachable coils which resulted in full exclusion of the fistula with full improvement of symptoms. During follow-up a stable clinical and morphological outcome was achieved. Clinical manifestations in HHT, with emphasis on neurological symptoms, are reviewed as well as the therapeutic options to deal with giant perimedullary fistula.
