The value of magnetic resonance imaging in the diagnosis of penile fracture

Abstract

Purpose We studied the use of magnetic resonance imaging in the diagnosis of penile fracture.Materials and Methods Between 1997 and 2012, fifteen patients (age range 17-48 years, mean age 37 years) with suspected penile fracture underwent MRI examinations. Ten patients were injured during sexual intercourse, whereas four patients were traumatized by non-physiological bending of the penis during self manupilation, one patient was traumatized falling from the bed. Investigations were performed with 1.5T MR unit. With the patient in the supine position, the penis was taped against the abdominal wall and surface coil was placed on the penis. All patients were studied with axial, coronal, sagittal precontrast and postcontrast T1-weighted TSE(TR/TE:538/13 msn) and T2-weighted TSE(5290/110 msn) sequences. All patient underwent surgical exploration. The follow-up ranged from 3 months to 72 months. Clinically all patients showed normal healing process without complications. In 11 patients a shortening and thickening of tunica albuginea was observed. Three patients have post traumatic erectil disfunction.Results In all patient corpus cavernosum fractures were clearly depicted on a discontinuity of the low signal intensity of tunica albuginea. These findings were most evident on T1WI and also depicted on T2W sequences. Images obtained shortly after contrast medium administration showed considerable enhancement only in rupture site. Subcutaneous extratunical haematoma in all patients were also recognizable on T2 WI. MRI findings were confirmed at surgery.Conclusions Magnetic resonance imaging is of great value for the diagnosis of penile fracture. Furthermore this method is well suited for visualising the post-operative healing process

Efficacy of magnetic resonance imaging for diagnosis of penile fracture: A controlled study

“…Additionally, MRI can show adjacent tissue damage such as to the urethra and corpus spongiosum and can help in differential diagnosis of penile fracture [ 2 ]. Guler et al [ 19 ] reported the high diagnostic value of MRI in penile fracture in a recent study with 15 patients. However, that study did not include a control group and could not actually define the diagnostic accuracy of MRI.…”

The pelvic pop: an extremely rare case of internal penile fracture presenting with scrotal hematoma and review of the literature

“… 7 Corporal tears are depicted on MRI as a discontinuity of the low signal intensity of the tunica albuginea that is best seen on T1-weighted images, but can also been seen on T2. 8 As demonstrated by our case, the quality and completeness of a penile MRI is crucial in diagnosing an internal penile fracture, especially in patients with a negative penile exploration and atypical presentation. Our patient had a negative initial penile MRI.…”

“…However, routine use of MRI is not common due to the costs, limited availability, and time requirements. Still, MRI is reasonable in an atypical presentation and physical findings of PF [12].…”
