Medical or biological term for an outpouching of a hollow (or a fluid filled) structure in the body
the medical term

In medicine or biology, a diverticulum is an outpouching of a hollow (or a fluid filled) structure in the body. Depending upon which layers of the structure are involved, diverticula are described as being either true or false. The word comes from Latin dīverticulum, "bypath" or "byway".

Bladder diverticula are balloon like growths on the bladder commonly associated with chronic outflow obstruction, such as benign prostatic hyperplasia in older males. Usually found in pairs on opposite sides of the bladder, bladder diverticula are often surgically removed to prevent infection, rupture, or even cancer. Calyceal diverticula are usually asymptomatic, but if a stone becomes lodged in the outpouching, they may present with pain. Urethral diverticula are usually found in women aged 30 to 70 years old, in between 1 and 6% of adult women. Since most cases are without any symptoms, the true incidence is unknown. Symptoms may vary from frequent urinary tract infections, painful sexual intercourse (dyspareunia), or symptoms due to cancer. A urethral diverticulum is located on the anterior vaginal wall, 1 to 3 cm inside the vaginal introitus. MRI is preferred as the imaging method of choice due to its excellent soft tissue resolution. On T2 weighted imaging, it shows a high signal in the diverticulum due to the presence of fluid inside it. Vaginal ultrasonography is highly sensitive in diagnosing the diverticulum, but it is strongly dependent on the skills of the operator.

A diverticulum of Kommerell is an outpouching (aneurysm) of the aorta where an aberrant right subclavian artery is located. It is unusual nomenclature, in that focal dilatations of a blood vessel are properly referred to as aneurysms. Cardiac diverticulum is a very rare congenital malformation of the heart that is usually benign.
