Title: Agenesis of the internal carotid artery with a trans-sellar anastomosis: CT and MRI findings in late-onset congenital hypopituitarism. Author: Mellado JM, Merino X, Ramos A, Salvadó E, Saurí A. Journal: Neuroradiology; 2001 Mar; 43(3):237-41. PubMed ID: 11305758. Abstract: A 29-year-old woman with a history of hypothyroidism since early childhood developed hypopituitarism. CT and MRI revealed anterior pituitary hypoplasia, an ectopic posterior lobe, a Chiari I malformation and agenesis of the right internal carotid artery with a trans-sellar anastomosis. This constellation of findings constitutes a previously unreported association in congenital hypopituitarism of late onset. The usefulness of imaging modalities and the pathogenic implications are also discussed.[Abstract] [Full Text] [Related] [New Search]
