Steven Johnson's Syndrome is a serious systemic disorder in which there are vesicobullous lesions involving the skin and mucous membranes. It can result as an immune response to an antigen or as a drug reaction. Most often it is considered as an allergic reaction. It is a self-limiting condition which responds to immediate management or may result in fluid loss, sepsis and death.

A 54-year-old man first was admitted with a right oculomotor nerve palsy that ameliorated spontaneously. Two months later, he was readmitted with right proptosis, ophthalmoplegia, and optic nerve involvement. MR showed an enlarged right cavernous sinus. There was dramatic improvement after high doses of steroids. MR findings 10 months later were normal. Thus, the diagnosis of the Tolosa-Hunt syndrome was established.
Raeder's syndrome constitutes facial pain and ipsilateral stenosis of the palpebral fissure, miosis and enophthalmos. It is divided into two groups. Group I includes cases with parasellar cranial nerve involvement and group II without parasellar cranial nerve involvement. It is often difficult to distinguish group II of Raeder's syndrome from Horner's syndrome. The latter is painless and is accompanied by anidrosis of the ipsilateral half of the face. In fact Raeder's syndrome may be caused by any lesion affecting the post-ganglionic oculosympathetic fibers distal to the bifurcation of the common carotid artery. Serious lesions of the internal carotid artery (ICA) may be responsible for this syndrome. This paper deals with two cases of group II of Raeder's syndrome. In the first case, a 60-year-old man, the angiogram revealed an aneurysm of the extracranial part of the ICA just below its entrance into the calvarium. In the second case, a 42-year-old man, a dissective aneurysm of the ICA was found. Surgery was not attempted in either of our patients for different reasons. Their symptoms ameliorated quickly with medical treatment.
