Background. Renal angiomyolipoma is a benign mezenchymal tumour with prevalence of 0,3–3 % of all surgically
resected renal tumours. Tumour is often associated with tuberous sclerosis complex or with another fakomatosis.
Tumour has typical pathological image in computer tomography notation that enables the diagnosis. Symptomatology
and possible complications depend on the tumour size. Large or symptomatic tumours are indicated for resection,
nephrectomy or local ablation.
Methods and Results. 612 patients with renal tumour were operated at the Department of Urology faculty hospital
in Pilsen. Angiomyolipoma occurred in 7 patients. Average age at the time of operation was 64 years, ratio female
and male was 5:2. Clinical symptomatology was expressed in 3 patients. The size of tumour was 2 to 8 cm, in 5 patient
the tumors were solitary. Translumbal tumour resection was performed in 3 patients. These tumours were at the
same time multifocal. Suspicion from tuberous sclerosis was pronounced in some care. The angiomyolipoma was
accidentally found in 2 cases of nephrectomy, which was indicated for other diagnosis.
Conclusions. We define diagnosis by means of CT notation in the most of patients. This notation is not typical by
any version of angiomyolipoma and we choose therefore surgical revision.
