“…Ultrasound examination is generally not useful since it is limited by bowel gas and surgical incisions [9,10]. Magnetic resonance imaging (MRI) is reported as the golden standard in preoperative assessing and classifying of fistula, because MRI allows direct visualization of the tracts and abscesses through to high soft tissue resolution [11,12].…”

A fistula extending from the gluteus to penis is an extremely rare entity. In this paper, we have highlighted novel variant of congenital penile to gluteal fistula complicated with gluteal and penoscrotal abscess in a previously healthy boy. A fistulous tract extending from the gluteus to penis has been shown by fistulogram. Bleomycin has been used in fistula tract with successful results in our patient.

“…Magnetic resonance imaging (MRI) provides multi-dimensional high-resolution imaging of soft tissues and is well tolerated, non-invasive, painless, and less embarrassing for the patient than other diagnostic techniques. Thus, MRI has been well accepted as the modality of choice for evaluating perianal fistulas (2).…”

MRI T2-Weighted Imaging and Fat-Suppressed T2-Weighted Imaging Image Fusion Technology Improves Image Discriminability for the Evaluation of Anal Fistulas

Objective To explore whether MRI fusion technology (combined T2-weighted imaging [T2WI] and fat-suppressed T2WI [T2WI- FS ]) improves signal differences between anal fistulas and surrounding structures. Materials and Methods A total of 32 patients with confirmed diagnoses of anal fistula were retrospectively studied. All available T2WI and T2WI- FS images for each patient were used to generate fusion image (T2WI- Fusion ) based on the addition of gray values obtained from each pixel via an MR post-processing work station. The discriminability of fistula, perianal sphincter, and perianal fat in T2WI, T2WI- FS , and T2WI- Fusion images was quantified with Fisher's scoring algorithm. For subjective visual image assessment by researchers, five-point scale scores were determined using a modified double-stimulus continuous quality-scale test to evaluate T2WI- FS , T2WI, enhanced axial three-dimensional-volumetric interpolated breath-hold examination (3D-VIBE), and T2WI- Fusion sequence images. The differences were subsequently compared. Results Mean Fisher scores for fistulas vs. sphincters obtained from T2WI- Fusion (F Fusion-fistula = 6.56) were significantly higher than those from T2WI (F T2WI-fistula = 3.35) ( p = 0.001). Mean Fisher scores for sphincters vs. fat from T2WI- Fusion (F Fusion-sphincter = 10.84) were significantly higher than those from T2WI- FS (FS FS-sphincter = 2.57) ( p = 0.001). In human assessment, T2WI- Fusion showed the same fistula discriminability as T2WI- FS , and better sphincter discriminability than T2WI. Overall, T2WI- Fusion showed better discriminability than T2WI, T2WI- FS , and enhanced 3D-VIBE images. Conclusion T2WI and T2WI- FS fusion technology improves signal differences between anal fistulas and surrounding structures, and may facilitate better evaluation of anal fistulas and sphincters.
