Adrenal cavernous hemangioma: is presurgical diagnosis with imaging test possible.

Objective: To describe a case of adrenal cavernous hemangioma in a 67 year old man who presented left lumbar pain.

Methods: Abdominal ultrasound, contrast enhanced ultrasound of the lesion, abdominal-pelvic CT scan, and then left adrenalectomy and pathology were performed

Results: Imaging studies showed a large solid-cystic mass with 12 × 11 cm diameters in the left adrenal gland, well defined, with calcifications, which showed peripheral arterial globular contrast enhancement on CT and ultrasound. The lesion displaced neighboring structures without other findings in the abdominopelvic study.

Bilateral kidney pseudotumor due to sarcoidosis: a radiological study case.

Objective: To report one case of bilateral kidney pseudotumor due to sarcoidosis in a 75 year-old man with prostatic carcinoma and hypertrophic pachymeningitis.

Methods: Renal Doppler, body CT, CT-guided renal biopsy, blood analysis including angiotensin converting enzyme (ACE), blood levels and test-treatment (corticosteroid response) were performed.

Results: The radiological studies performed showed bilateral kidney masses and pulmonary calcified hilar adenopathies.

[Renal pseudoaneurysm and arteriovenous fistula: color doppler study of a post-lithotripsy simple cyst].

Objectives: To describe the clinical and radiological (color doppler ultrasound, CT scan and arteriography) features of a case of renal arteriovenous malformation type mixed fistula with pseudoaneurysm in a female patient after extracorporeal shock wave lithotripsy.

Methods/results: We report one case of secondary vascular malformation in a 54-year-old female patient who underwent extracorporeal shockwave lithotripsy, presenting as recurrent hematuria. Ultrasound detected a "cystic" formation newly appeared after lithotripsy, being the diagnostic made by a color doppler study which showed a mixed high speed arteriovenous turbulent flow.

[Synchronous chromophobe renal carcinoma and centrocytic lymphoma].

Objectives: To report a case of synchronic neoplasia--chromophobe renal cell carcinoma and low grade non Hodgkin lymphoma--in a 38-year-old male patient, because, although association of these two neoplasias is known, the fact of renal neoplasia being a chromophobe carcinoma is rarely referred to in medical bibliography (3 cases described after Med-Line search).

Methods/results: The diagnostic study included ultrasound and CT scan in a patient presenting with in non specific abdominal symptoms and neck adenopathy; patient underwent left radical nephrectomy and excision of neck adenopathy. Histologic and immuno-histochemical studies revealed the coexistence of chromophobe type renal cell carcinoma and diffuse centrocytic lymphoma.

[Perirenal involvement in Waldenström disease].

Objective: To describe radiological, histological findings and cytometric features of perirenal masses: an unusual involvement pattern of the kidney by Waldenström disease. This pattern, not associated with nodal regional disease should be considered in the differential diagnosis of perirenal pathology (extramedullary hematopoiesis, liposarcoma, haematoma..
