Hémosidérose du système nerveux central et son association avec un macroadénome hypophysaire: rapport de cas

Abstract

Nous rapportons le cas clinique d´un patient de 58 ans qui présentait des céphalées depuis 3 mois dont les investigations paracliniques ont permis de poser le diagnostic d´hémosidérose du système nerveux centrale et son association rare avec un macro-adénome hypophysaire.

Postoperative vasospasm and cerebral infarction in a patient with large pituitary adenoma and cerebral superficial siderosis

“…[9] Mapaga and Martinez reported several causes of cerebral superficial siderosis but did not mention pituitary adenoma. [10] Only two cases of pituitary adenoma (prolactinoma) and cerebral superficial siderosis have been previously described. [10,15] Steinberg et al speculated that cerebral superficial siderosis could have been caused by pituitary apoplexy of the prolactinoma.…”

“…[10] Only two cases of pituitary adenoma (prolactinoma) and cerebral superficial siderosis have been previously described. [10,15] Steinberg et al speculated that cerebral superficial siderosis could have been caused by pituitary apoplexy of the prolactinoma. [15] Although the patient of Steinberg et al had visual disturbances, he refused surgical treatment; therefore, only medication for prolactinoma was prescribed.…”

“…[ 10 ] Only two cases of pituitary adenoma (prolactinoma) and cerebral superficial siderosis have been previously described. [ 10 , 15 ] Steinberg et al . speculated that cerebral superficial siderosis could have been caused by pituitary apoplexy of the prolactinoma.…”

“…[ 6 , 9 , 16 ] Subarachnoid hemorrhage from central nervous system tumors including pituitary adenoma may also result in cerebral superficial siderosis. [ 9 , 10 , 15 ] However, to the best of our knowledge, concomitant cerebral superficial siderosis, pituitary adenoma, and cerebral vasospasm seem rare. There is no description of postoperative symptomatic cerebral vasospasm in a patient with nonfunctioning pituitary adenoma and cerebral superficial siderosis.…”

Surdité bilatérale révélant une sidérose superficielle du système nerveux central : une observation clinique

“…En cas de surdité, on peut observer un dépôt sur le paquet nerveux acoustico-facial avec disparition de l'hypersignal du liquide cérébro-spinal normalement retrouvé entre le nerf facial et le nerf cochléo-vestibulaire sur les séquences CISS 3D (10). L'atteinte médullaire se traduit par un signal hypointense périmédullaire en T2 (5,10), non retrouvée chez notre patient. La recherche étiologique nécessite une exploration complète de l'encéphale et de la totalité du canal rachidien par IRM injectée.…”
