Plaques from patients with recently symptomatic carotid disease have a predominance of M1-macrophages and higher lipid content than femoral plaques, consistent with a more unstable plaque.

Oncocytomas are rare tumours of the adrenal glands whose malignant potential is difficult to assess with certainty. We report a case of an adrenal oncocytoma and present a review of the literature particularly with regards to the radiological and histopathological features and their impact on the management.Adrenal oncocytomas are usually identified incidentally on imaging and can achieve large sizes. They should be considered in the differential diagnosis of any large upper abdominal lesion including those apparently arising from the liver as in this case report. MRI scan appears to be the ideal imaging modality to characterise such lesions. There seems to be little benefit in biopsying these masses and surgery remains the most optimal management. It remains difficult to predict metastatic behaviour based on histological findings and so long term surveillance is advisable.

Arterial thoracic outlet syndrome is relatively rare and often exclusively seen in the presence of bony anomalies. High-altitude (HA) travel is commonly associated with thrombosis; however, arterial thromboembolism is less frequently described. We describe a case of a young man with undiagnosed bilateral cervical rib, who went for an HA trek, subsequent to which developed acute limb ischaemia of right arm. Diagnostic workup revealed a subclavian artery aneurysm as well along with complete bony bilateral cervical ribs. Thoracic outlet syndrome should be kept as a differential diagnosis in a case of acute limb ischaemia in a healthy adult.
