[Diagnosis and treatment of cystic tumors of the adrenal gland. Report of 2 cases].

Two cases of cystic tumour are reported. The first consisted of a pseudohaemorrhagic cyst of the right adrenal gland discovered during aetiological assessment of HT refractory to medical treatment. Plasma and urinary assays did not reveal any abnormality suggestive of secreting adrenal tumour. Imaging (ultrasonography. CT and MRI) was in favour of a necrotic malignant tumour and a normal isotope scan (MIBG iodine 131) eliminated phaechromocytoma. Adrenalectomy was easily performed via a subcostal laparotomy and the postoperative course was uneventful. The second case consisted of a right adrenal cyst detected incidentally on ultrasonography. The laboratory assessment demonstrated only a slight elevation of urinary metanephrine and imaging (CT and MRI) was not suggestive of a malignant lesion. Simple annual CT follow-up was decided in this case. The various pathological types of rare cystic lesion of the adrenal gland are described with particular emphasis on their diagnostic and therapeutic modalities.
