Ehlers-Danlos syndrome is a group of inherited disorders of the connective tissue that feature hyperextensibility of the joints and changes to the skin, including poor wound healing, fragility, and hyperextensibility. However, Ehlers-Danlos vascular type (type IV) also is known to cause spontaneous rupture of hollow viscera and large arteries, including arteries in the intracranial circulation.

Patients with Ehlers-Danlos syndrome may also have mild facial findings, including lobeless ears, a thin upper lip, and a thin, sharp nose. The distal fingers may appear prematurely aged (acrogeria). In the absence of a suggestive family history, it is difficult to separate Ehlers-Danlos vascular type from other forms of Ehlers-Danlos. Ehlers-Danlos vascular type is caused by mutations in the COL3A1 gene; it is inherited in an autosomal dominant manner.
