Abstract:
Pedunculated hepatocellular carcinoma is an unusual form of hepatocellular carcinoma protruding from the liver with or without a pedicle. We present a case of pedunculated hepatocellular carcinoma misdiagnosed as right adrenal tumor on MRI and FDG PET/CT. Intraoperative exploration revealed the mass was attached to the liver, but the right adrenal gland was intact. Laparoscopic biopsy revealed poorly differentiated hepatocellular carcinoma. This case indicates it may be difficult to diagnose pedunculated hepatocellular carcinoma because it is hard to define its origin on imaging. Elevated alpha-fetoprotein level and a history of viral hepatitis may be helpful for the diagnosis.

Anatomy of the Adrenal Glands
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.

Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...
Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...
