Vascular involvement is not infrequent in Behcet's disease (BD). It is generally seen in the form of superficial thrombophlebitis or occlusion of major veins. In rare instances, arterial occlusion and aneurysm formation may be seen in BD. We reported a young male with BD, diagnosed at the age of twenty for relapsing and remitting oral ulceration, skin rash, arthralgia and ocular painful redness for three years. At the age of 21, he had recurrent abdominal aortic aneurysm and inconspicuous neurological manifestations including dizziness, tinnitus and transients of blurred vision. The carotid angiography disclosed the occlusion of bilateral common carotid arteries (CCA). A carotid endarterectomy was subsequently performed to reduce the risk of stroke. The pathological examination of the occluded segment of CCA revealed chronic inflammation, which was attributable to BD. There was no atherosclerotic change. To the best of our knowledge, this is the first case report of concurrent bilateral CCA occlusion and relapsing abdominal aortic aneurysm. Even in the absence of specific neurological symptoms, we suggest that cerebrovascular investigation need to take into consideration in BD patients with unexplained cranial symptoms.

Pheochromocytomas have been described in association with rare vascular abnormalities, most common of them being renal artery stenosis. A 45-year-old woman was admitted to our hospital with complaints of headache, sweating, anxiety, dizziness, nausea, vomiting and severe hypertension. For the last several days, she was having a dull aching abdominal pain with a palpable, pulsatile, expansile and non-tender mass in the epigastric region. Hypertension was confirmed biochemically to result from excess catecholamine production. Abdominal computed tomography revealed the presence of a right adrenal pheochromocytoma. Magnetic resonance imaging of the abdomen demonstrated an abdominal aortic aneurysm (AAA) of maximum transverse diameter of 4.5 cm with 3 cm lumen. Surgical removal of pheochromocytoma resulted in normalization of blood pressure to normal. Because of the asymptomatic 4.5 cm aneurysm, our patient was advised for periodic follow-up. To our belief, this is the first such case report emanating from India, citing this rare association between pheochromocytoma and AAA. It is concluded that when the two diseases occur simultaneously, both must be diagnosed accurately and treated adequately. Possible mechanisms of such an uncommon association are also discussed.
