Cerebrofacial arteriovenous metameric syndrome with hypopituitarism: a rare association

Case of cerebrofacial arteriovenous metameric syndrome (CAMS) in a 9-year-old boy is described with arteriovenous malformation simultaneously involving the brain and face, with characteristic CAMS type 1 and 2 involvement. This patient demonstrates the wide spectrum of clinical manifestations of CAMS, and in this particular case, the patient exhibits features of hypopituitarism—an association that was not previously described in the literature to our knowledge. Awareness of the underlying embryological abnormality and recognition of resultant clinical and radiological presentations are paramount for diagnosis and treatment.
