CASE 617: PROSTATE on SWE TRUS with BIPLAN PROBE, Dr NGUYEN MINH THIEN, Dr PHAN THANH HAI, MEDIC MEDICAL CENTER, HCMC, VIETNAM

Male patient 64yo with fever and voiding discomfort for month.

Digital rectal examination detected a big prostate with a hard nodule on right side.

On MRI there were a 22x15mm hard node of right lobe and another one, 12x16mm, on the left of prostate which concern neoplastic foci , but  PSA=1.75 ng/mL;  F/T=20%

At Medic, an SWE elastography TRUS with biplane probe was done

On TRUS B-mode,  peripheral area of right lobe exists a 16x18 mm hypoechoic nodule, not well-limited,  hypervascular and irregular capsule of right lobe.

On strain elastography, nodule is harder than transitional area while surrounded area of right lobe is softer than the nodule.

On 2D SWE, stiffness of nodule on right side has got a value of 50 kPa [mild hard] while lesion of transitional area of left lobe of 47 kPa.

By via  transperineal a biopsy of prostate was perfomed and histopathological result is TB of prostate and subacute prostatitis.

Conclusion: 

SWE TRUS with biplan probe helps imaging lesions of prostate with more  information to plan for treatment better.
