=Abstract=A retrospective review of 22 cases of angiographically occult vascular malformations (AOVMs), treated at our institution during the past 6 years, was conducted to define better the clinical and radiological manifestations as well as the effective treatment modality of these lesions. There were 12 (54.5%) arteriovenous malformations (AVMs), 8 (36.4%)cavernous angiomas, 1 (4.5%) venous ...

Vascular malformations of the small bowel are uncommon, yet remain a cause of gastrointestinal bleeding in up to 5% of patients with gastrointestinal hemorrhage. The diagnosis of these lesions is suspected in patients with a gastrointestinal source of blood loss with a negative upper endoscopy and colonoscopy. Enteroscopy remains the mainstay in diagnosing these lesions. Therapeutic options inc...

Isolated involvement of the clitoris by vascular malformation (VM) is very rare. Clinically, the lesion simulates female pseudohermaphroditism. A five-year-old girl presented with clitoromegaly and a clinical diagnosis of solitary VM of the clitoris was made. Magnetic resonance imaging showed characteristic features and confirmed the diagnosis and the extent of the VM. This is the first reporte...

This is predominantly due to an unclear understanding of the natur...
