BACKGROUND
Pseudoaneurysm is very rare in Head Neck region. Psedoaneurysm or false aneurysm develops only from adventitia, lacking one or more of the layers of the vascular wall. Correct clinical diagnosis and management is challenging.
CASE REPORT
19 years old male patient presented with a swelling in the left parotid region following trauma in the same region with the sharp end of a scissor. USG and Colour Doppler were suggestive of a A-V malformation. MRI and MR Angiogram showed it to be a pseudoaneurysm arising from superficial temporal artery. Superficial parotidectomy was done followed by ligation of superficial temporal artery. Aneurysm was subsequently excised.
DISCUSSION
Pseudoaneurysms are relatively rare in the external carotid system. It is most commonly seen in association with superficial temporal artery in external carotid system. Several anatomical factors predispose to such propensity. Imaging studies followed by surgical excision remains the treatment of choice.
CONCLUSION
Penetrative trauma in the head–neck region is not uncommon. Their exterior entrance may appear benign but deeper part may have significant and dangerous injuries. Any pulsatile mass that follows trauma in the head and neck regions might be a case of pseudoaneurysm.
