The role of MDCT in diagnosis of congenital venous anomalies : case report

Abstract EN

Congenital abnormalities of the major mediastinal venous structures occur in less than 2 % of people who have no other abnormalities.

Venous malformations are the most common vascular malformation, accounting for 44–64% of all vascular malformations.

Multi-detector computed tomography (MDCT) is beneficial in the diagnosis and workup treatment planning of congenital anomalies.

The current study presents a case report of a 27-year-old male who came to the CT department at Al-Shifa Hospital for evaluation of venous drainage patterns to the chest.

In the first exam (one side contrast media injection), congenital absent both subclavian and brachiocephalic veins with blood seen draining through numerous small mediastina venous collaterals are observed during the two exams.

The second exam (bilaterally and simultaneously contrast media injection) gives the same diagnosis in addition to huge network of collaterals around the lower esophagus and gastroesophageal junction forming cavernous transformation (significantly increased).

Highly recommended to use direct-MDCT angiography and venography injecting contrast media bilaterally and simultaneously via the upper extremity.
