Although absence of the common carotid artery (CCA) is a rare anomaly, the specific configuration in our case makes it extremely rare. Clinical, angiographic, ultrasonographic, and embryologic correlations of this anomaly are discussed after the case report.

Sir, Verrucous haemangioma (VH) is a rare, congenital and localized vascular malformation that appears at birth or in early childhood with a predilection for the lower extremities (1). It later becomes verruciform and tends to enlarge and spread peripherally. The linear form of VH is extremely rare and only a few case reports have been presented in the literature (2 – 4). We describe a linear V...

Hemangiomas are benign vascular malformations of childhood characterized histologically by endothelial proliferation and clinically by rapidly expanding erythematous nodules. The incidence in newborns is approximately 2% to 3%, making them the most common tumors of infancy. Hemangiomas are typically classified as superficial (cutaneous), deep (subcutaneous), or mixed (cutaneous and subcutaneous...

Vein of Galen malformations (VoGMs) are rare vascular malformations resulting from persistent shunting of primitive choroidal vessels into the median prosencephalic vein of Markowski. VoGMs are associated with poor clinical outcome with a reported 76.7% mortality if left untreated. We present an exceedingly rare case of a giant, untreated VoGM measuring 7.8 × 5.5 × 7 cm in a 42-year-old man. Th...

PURPOSE To report 5 cases of orbital lymphangioma. METHODS All patients underwent ophthalmological, clinical and neuroradiological evaluation. RESULTS At presentation all patients (4 children and one adult patient) had unilateral proptosis. Restricted eye movement was present in 3 patients, ptosis and amblyopia in 2. Compressive optic neuropathy with visual loss was noticed in one patient. ...

Congenital anomalies of the great thoracic vessels have been reported in 20% of dogs and cats. In some cases, the vascular ring anomalies remain unrecognized throughout the lifetime of an animal. This report describes a case with an unusual vascular ring anomaly (VRA) that was detected during dissection on a cadaver of an approximately two-year-old male native mixed breed dog. No history of the...

A pulmonary arteriovenous malformation (PAVM) is a rare pulmonary vascular anomaly presenting as dyspnea or recurrent epistaxis. Ebstein's anomaly (EA), a congenital cardiac malformation, is also a rare condition. There have been no reports concerning the co-existence of PAVM with hereditary hemorrhagic telangiectasia (HHT) and EA. A 40-year-old woman was admitted with a 2-month history of incr...
