What lesions are common in the kidneys of patients with tuberous sclerosis, and is this likely to be one?
Angiomyolipomas are seen in 55-75% of patient with tuberous sclerosis and typically have this appearance - an echogenic nodule.
How do the angiomyolipomas identified in tuberous sclerosis patients differ from those found sporadically in 'normal' patients?
They tend to be multiple and bilateral.
There is a 0.8 cm focus of hyperechogenicity within the left renal parenchyma, consistent with an angiomyolipoma.
