Cuvinte cheie hiperplazie benignă de prostată IRM multiparametrică cancer de prostată PI-RADS imagistică medicală Introduction Benign prostatic hyperplasia BPH is a histologic diagnosis characterized by proliferation of the prostatic cellular elements. Benign hyperplastic nodules are most commonly seen in the transition zone, but they can also protrude into the peripheral prostate volume normal radiology or even beyond the prostatic capsule, appearing as an exophitic pelvic mass or as a mass within the bladder 2.
Usually, there is a direct relationship between prostate enlargement and symptoms severity, although many patients with small prostates also present urinary obstruction, because of the strategically position of the adenoma, sitting right on prostate volume normal radiology bladder outlet 2. The initial evaluation should asses the frequency and severity of symptoms by using the International Prostate Symptom Score IPSS 4 and it should also include a digital rectal examination and urinalysis.
Si as mai vrea sa stiu pentru cei care au urmat si tratamentul radiologic, care sunt efectele rele, cum se simt persoanele dupa aceste radiatii. Cristiana Eugenia Simionescu The study of precancerous lesions of the prostate is important for understanding prostatic carcinogenesis and for developing potential. Simptome - Pacientul este obligat sa se trezeasca de mai multe ori pe noapte pentru a urina si are probleme cu golirea completa a vezicii slabirea jetului urinar, picaturi. Sotul meu are adenom de prostata are si diabet A fost la medicul urolog si ia dat tratament medicamentos - Omnic si nu da rezultate. Prostate cancer most commonly metastasizes to the bones, lymph nodes, and may invade rectum, bladder and lower ureters after local.
Enlargement of the prostate associated with a palpable nodule and elevated PSA prostate specific antigen level requires imaging methods of diagnosis, such as transrectal ultrasonography which provides a more accurate assessment of prostate volume than digital rectal examination does 5 and MRI for the characterization of the prostatic tissue, due to its excellent contrast resolution.
Case report We present the case of a year-old patient who was referred to the urology department of our clinical institute three years ago, with lower urinary tract symptoms LUTS. PSA value was Digital rectal examination and transrectal ultrasonography revealed an increased prostate.
The patient was directed to our department, where we performed an MRI investigation, in order to rule out prostate cancer, possibly associated with BPH. A written consent was taken from the patient before entering the scanner room, after he was interviewed about his medical history, possible allergies, previous examinations and MRI contraindications.
An intravenous antispasmodic agent is routinely used, in order to decrease the artifacts generated by intestinal motility, after a venous line is secured. He was investigated on a Toshiba 1.
High-resolution multiplanar T2 WI are morphological sequences ideal for the prostate anatomy evaluation. Dynamic contrast enhancement DCE and diffusion-weighted DWI are functional sequences, corresponding to angiogenesis and cellular density, respectively. MR-spectroscopy MRS is another functional sequence that correlates with cellular turnover, but we do not perform it routinely.
Article Introduction Colorectal cancer CRC is the third most common cancer in men and the second most common in women. Although screening, addressability and increased awareness have augmented the number of cases in the non-metastatic setting, approximately one in four individuals with CRC will be diagnosed in stage IV. Additionally, because this improvement in survival has also been associated with substantial health care financial burden, appropriate selection of patients for specific treatments is of utmost importance. Currently, there are several biomarkers that help clinicians in making the optimal treatment decision: KRAS, NRAS, BRAF mutations, human epidermal growth factor receptor 2 HER2 amplification and microsatellite instability MSI or mismatch repair MMRthey all play a significant role in the process, facilitating selection of the right treatment for the right patient. The aim of this review is to provide clinicians with an update on the particular features of these biomarkers.
The scanning protocol is listed in Table 1. Contrast media is injected in a volume of 0.

Table 1. The routine multiparametric MRI protocol for prostate imaging used for the patient Imaging findings showed an enlarged prostate, with its three diameters of 51 mm, 61 mm and 41 mm longitudinal diameter, axial diameter and anteroposterior diameter, respectivelywith an estimated total volume of The transitional zone TZ appeared asymmetrically enlarged, predominantly on the right half of the prostate, which led to the compression of the urethra being displaced to the left and thinning the peripheral zone PZespecially on the right side of the base.

The PZ showed diffuse decreased signal intensity on T2WI and no restricted diffusion, typical aspect for chronic inflammatory lesions.
The TZ presented multiple small cystic areas and a multinodular structure because of the presence of stromal and glandular nodulesthe biggest one being located in the right middle third and apex of the TZ, with an axial diameter of 38 mm.
Value of ultrasound elastography in the diagnosis and management of prostate carcinoma.
We noticed a bulging aspect of the macronodule described in the right TZ, protruding into the neighboring PZ, with a central area of increased signal intensity on diffusion WI and decreased signal intensity on ADC map, but a negative dynamic contrast enhancing DCE curve Figures 1 and 2. Figure 1.
This particular right TZ nodule has been marked with a final PI-RADS score of 3, which means that the presence of clinically significant cancer is equivocal. Discussion BPH nodules appear as a mixture of signal intensities, ranging from hypointense to hyperintense on T2 WI, depending on the proportion of their prostate volume normal radiology and glandular components.

Prostate volume normal radiology are well-delineated nodules that arise in the TZ, involving the periurethral regions, but sometimes they can bulge the surgical capsule, so they can be found in the PZ.
The patient was referred for prostatic biopsy one month after the MR examination, considering the elevated PSA value, which revealed a benign appearance of the sample: polymorphic aspect on account of a chronic inflammatory, non-specific process. Retrospectively, we can conclude that DWI changes and elevated PSA value may be due to this chronic inflammatory, non-specific process. The patient received anti-inflammatory treatment and remained under urological surveillance.
Conclusions Multiparametric MRI is a precious tool in prostate tissue characterization, completing clinical and biological information, but in case of BPH, a suspected prostate carcinoma in the TZ may represent a real challenge for the radiologist.
