Aggressive angiomyxomas are rare tumours that arise in the pelvis and typically cross the the levator ani muscles. Despite its name, it is essentially a benign tumour and the term "aggressive" is given due to a predilection for local recurrence. Only rarely does it metastasize. Epidemiology It...
The uterine tube, also known as the fallopian tube, is a paired structure that bridges between each ovary and the uterus and functions to convey the mature ovum from the former to the latter. If conception occurs, it normally does so within the tube. It can be affected by a wide range of patholo...
Osteitis pubis (OP) is characterised by non-infectious inflammation of the pubic symphysis. Clinical presentation Presentation is typically with varying degrees of pelvic and/or perineal pain, reproduced on hip adduction. Pathology Although the aetiology is sometimes unknown, the most comm...
Shenton line is an imaginary curved line drawn along the inferior border of the superior pubic ramus (superior border of the obturator foramen) and along the inferomedial border of the neck of femur. This line should be continuous and smooth. Interruption of the Shenton line can indicate (in ...
The ovaries are paired female gonads of the reproductive and endocrine systems. They lie within the ovarian fossa on the posterior wall of the true pelvis. Gross anatomy The ovaries are ovoid in shape and measure approximately 1.5-3.0 cm x 1.5-3.0 cm x 1.0-2.0 cm (length x width x thickness) ...
The cervix is the lower constricted segment of the uterus. Owing to its relationships, it is less freely movable than the uterine body, so that the latter may bend on it. The long axis of the cervix is therefore seldom in the same straight line as the long axis of the uterine body. Gross anato...
The uterus is a hollow, thick-walled, muscular organ of the female reproductive tract that lies in the lesser pelvis. Gross anatomy The uterus has an inverted pear shape. In the adult, it measures about 7.5 cm in length, 5 cm wide at its upper part, and nearly 2.5 cm in thickness. It weighs ...
The vagina is a midline fibromuscular tubular structure positioned in the female perineum extending superiorly to the cervix and uterus in the pelvis. Gross anatomy The vagina is 8-10 cm in length, extending posterosuperior from the vestibule through the urogenital diaphragm to the uterus. Th...
The piriformis muscle is a muscle in the gluteal region of the lower limb. Summary origin: sacrum course: exits the pelvis through the greater sciatic foramen insertion: greater trochanter of the femur action: abduction and lateral rotation of the thigh arterial supply superior gluteal ar...
The sciatic nerve arises from the sacral plexus from the roots of L4-S3 and runs through the buttock and down the lower limb. It is the longest and widest single nerve in the body. Summary origin: sacral plexus (L4-S3) course: exits the pelvis through the greater sciatic foramen to enter the ...
The term pelvis can refer to either the bony pelvis or the pelvic cavity. Bony pelvis The bony pelvis is formed by the sacrum and coccyx and a pair of hip bones ("ossa coxae"), which are part of the appendicular skeleton. Its primary function is the transmission of forces from the axial skelet...
