Letter Case Reports[Parsonage-Turner syndrome in positive HIV patients. Letter].
-
Neurological complications are frequent in patients with the acquired immunodeficiency syndrome (AIDS). They are caused by neural structures being affected by the virus itself, and/or the development of opportunist infections and neoplasias secondary to the immunodepression. Cerebral toxoplasmosis and human immunodeficiency virus (HIV) encephalopathy are the commonest encephalopathic disorders seen in these patients. ⋯ Although MR is more sensitive for the detection of lesions, particularly those in the white matter, CT is still the most widely used technique since its more readily available. Also it needs less cooperation from the patient. Although on some occasions combination of both techniques may suggest the aetiology of the lesion, these techniques are non-specific.

Case Reports[Pontine hemorrhage as a cause of peripheral facial paralysis].
Bell's palsy is the most frequent type of peripheral facial nerve paralysis. Nevertheless there are other less frequent causes of peripheral facial palsy, among which, we can find lesions in the brain stem affecting the seventh cranial nerve nucleus or its fibers. These lesions of the pons which paralyze the muscles of the face are often accompanied by lesions to other structures in the vicinity of the nucleus. We present the case of peripheral facial nerve palsy caused by hemorrhage in the pons, seen both on brain CT-scan and MRI, which affected the nucleus of the seventh cranial nerve and was not accompanied by any other clinical manifestations due to lesions of structures placed in the vicinity of this nucleus.

[Neuroimaging, CT and MR brain findings in a case of McCune-Albright syndrome].
McCune-Albright syndrome is characterized by the triad of polyostotic fibrous dysplasia, precocious puberty, cutaneous pigmentation and cafe-au-lait spots. A 23-year-old woman with McCune-Albright is reported. Findings on CT scan and magnetic resonance imaging of the skull in an affected girl with McCune-Albright syndrome are shown, and also the histopathological study of the right temporal bone biopsy.
