The Thyroid Gland01:23

The Thyroid Gland

4.2K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Gross Anatomy of the Liver01:17

Gross Anatomy of the Liver

792
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...

The Parathyroid Glands00:59

The Parathyroid Glands

2.3K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Hepatic Portal System01:21

Hepatic Portal System

1.8K
The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...

Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

4.9K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Summary

A porta hepatis mass was incidentally discovered in a 61-year-old woman. Further investigation, including CT and endoscopic ultrasound-guided biopsy, was performed to characterize the lesion.

Area of Science:

  • Hepatobiliary Imaging
  • Gastrointestinal Endoscopy
  • Nuclear Medicine

Background:

  • A 61-year-old woman presented with an incidentally discovered porta hepatis mass.
  • Past medical history includes pulmonary embolism, pulmonary abscess, and hypothyroidism treated with levothyroxine.
  • No history of liver disease, cancer, or trauma was reported.

Observation:

  • Physical examination and laboratory data, including tumor markers (CEA, CA 19-9), were unremarkable.
  • CT imaging revealed a mass in the porta hepatis.
  • Endoscopic ultrasound-guided fine-needle biopsy was performed due to concerns for malignancy.

Findings:

  • The porta hepatis mass was characterized using multiphasic contrast-enhanced CT.
  • Whole-body iodine 131 (131I) scintigraphy was also performed.
  • Endoscopic ultrasound-guided fine-needle biopsy provided tissue for histopathological analysis.

Implications:

  • This case highlights the importance of comprehensive imaging and biopsy for characterizing incidental liver region masses.
  • Diagnostic workup for porta hepatis masses requires a multidisciplinary approach.
  • Accurate characterization is crucial for appropriate patient management and treatment planning.
