Which of the following is considered a function of the lymph node?

Symptoms associated with adrenocortical carcinoma include all of the following except:

Indications for a sonogram of the adrenal glands include all of the following except:

Which of the following adrenal neoplasms is most likely to infiltrate surrounding structures?

A urinoma is most likely to develop in which of the following regions?

The most common neoplasm to develop in the retroperitoneum is a:

Which of the following statements correctly describes the adrenal glands?

The anterior pararenal space is most accurately defined as the area between the:

Young children have a predisposing factor for developing which of the following adrenal neoplasms?

Which of the following structures form the anterior border of the retroperitoneum?

All of the following structures are located within the perirenal space except:

Hemorrhage within the retroperitoneum may be caused by all the following conditions except:

Retroperitoneal Organs

Retroperitoneal organs have peritoneum only on their anterior side and lie between the parietal peritoneum and abdominal wall.
Key retroperitoneal organs include kidneys, ascending colon, descending colon, duodenum, and pancreas.

Intraperitoneal Organs

Intraperitoneal organs are suspended in the abdominal cavity by mesentery.
Notable intraperitoneal organs encompass the stomach, spleen, liver, bulb of the duodenum, jejunum, ileum, transverse colon, and sigmoid colon.

Hormonal Effects

Glucocorticoids are hormones that modify the body’s response to inflammation.

Tumor Classification

Rhabdomyosarcoma is a malignant neoplasm derived from striated muscle.

Anterior Pararenal Space

The anterior pararenal space includes various structures except for the inferior vena cava (IVC).

Adrenal Conditions

Bilateral adrenal hyperplasia correlates with hyperaldosteronism.
Symptoms of adrenocortical carcinoma typically include hypertension, muscle weakness, weight loss, and abdominal pain; severe anxiety is not a symptom.

Lymph Node Function

Lymph nodes play a crucial role in forming antibodies to combat infection.

Diagnostic Indications

A sonogram of the adrenal glands is indicated for tachycardia, severe anxiety, hypertension, and weight loss; renal insufficiency is not an indication.

Neoplasms in Retroperitoneum

Liposarcoma is the most common neoplasm found in the retroperitoneum and is likely to infiltrate surrounding structures.

Urinoma Development

Urinomas are most likely to occur in the perinephric space.

Adrenal Gland Characteristics

The suprarenal arteries originate from the aorta, renal arteries, and inferior phrenic arteries; the right suprarenal vein drains into the right renal vein.

Spaces and Structures

The anterior pararenal space is defined as the area between the posterior peritoneum and Gerota fascia.
Within the perirenal space, the psoas muscles are not located.

Hemorrhage Causes

Retroperitoneal hemorrhage can result from trauma, neoplasm, infarction, and ruptured aneurysm; abscess formation is not a cause.

Pediatric Neoplasm Risk

Neuroblastoma is a common adrenal neoplasm in young children, while nephroblastoma is also a concern but less frequent in this demographic.
