Anterior Fibromuscular Stroma
Stroma fibromuscularis anterioris
- Acronym: AFMS
Definition
The anterior fibromuscular stroma of prostate (AFMS; Fibromuscular tissue of prostate) forms the entire anterior surface of the prostate as a thick, nonglandular apron, shielding from view the anterior surface of the three glandular regions.
The anterior fibromuscular stroma of prostate is composed of vertically oriented smooth muscle bundles continuous with the bladder smooth muscle and covers the anterior surface of the prostate as a nonglandular layer.
On MR imaging, axial T2-weighted image shows a symmetric markedly hypointense signal along the anterior aspect of the prostate,
