Funktioner av abdominal ultraljud med kontrast: indikationer

The renal cyst masses in some cases, especially category II to III lesions, may be over evaluated by the Bosniak criteria based on MR findings. It is necessary to combine MR features with CT findings in evaluation and management of these cases with renal cystic masses. 1 Introduction Bosniak 1 and 2 lesions are likely to be benign whereas Bosniak 3 and 4 lesions are more likely to be cancerous. What makes a growth on the kidney suspicious is when it appears to be solid on the imaging and when it "picks up" the dye that is used during CT or MRI scans (we call this enhancement). A Bosniak 3 cyst will be cancerous 50% of the time and unless there are co-morbidities that preclude surgery are usually dealt with in a similar fashion to solid renal/kidney masses.

The malignancy rate of Bosniak III renal cysts was 40% (29/72), which is significantly lower than 90% (18/20) for surgically resected Bosniak IV renal cysts (p < 0.0001). The malignancy rate of Bosniak IIF renal cysts was 38% (3/8), which is not significantly different from the rate of malignancy of Bosniak III renal cysts (p = 1.000). The Bosniak classification for Renal Cysts was developed in late 1980s for management of complex Cystic Renal Lesions. Bosniak classification system has also been utilized with some advantages for magnetic resonance imaging.

6, 7 Category 2F lesions were created later as a group to be followed to prove cyst benignity. 8, 9 However, in the era of active surveillance for small renal masses differentiating a surgical lesion from one that can be monitored has become increasingly important. 10, 11 In our study, one-half of small (< 4 cm) Bosniak category 3 and 4 cystic renal lesions were downgraded, and most (88%) of the small Bosniak category 2F lesions were downgraded or remained stable on follow-up. In none of the patients with lesions that were Bosniak category 3 or 4 at follow-up imaging did recurrent or metastatic disease develop. Approximately one-half of small (< 4 cm) Bosniak category 3 and 4 cystic renal lesions were downgraded, and the majority (88%) of small Bosniak category 2F lesions regressed or remained stable during active surveillance. Therefore, small size should be a consideration for conservative management. 2020-01-24 · All Bosniak 3/4 lesions with initial SV less than 0.05 cc were downgraded.

Therefore, small size should be a consideration for conservative management. 2020-01-24 · All Bosniak 3/4 lesions with initial SV less than 0.05 cc were downgraded. CONCLUSION: FP and SV are useful quantitative surrogates for Bosniak category and future behavior, respectively. Growth of small renal lesions by an increase in fluid volume and FP leads to a downgrade in Bosniak category.

* Study developed at Clínica de Medicina Nuclear e Radiologia de Maceió (Med-RadiUS), Maceió, AL, Brazil. The Bosniak classification separates renal masses into 1 of 5 categories: 1, simple cyst; 2, minimally complex with single thin (1‐mm) septations, a thin calcified wall, or both (well‐marginated, nonenhancing, high‐attenuation renal lesions <3 cm are also included); 2F, increased number of septa, minimally thickened or enhancing septa or wall, or thick calcifications (hyperdense cysts Bosniak was the normal radiological assessment procedure for cystic renal lesions.
