Thoracic Aorta

Thoracic Aorta

The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

The Thoracic Cage: Sternum

The Thoracic Cage: Sternum

The thoracic or rib cage forms the body's thorax (chest) portion. Its primary function in the body is to protect vital organs in the thoracic cavity, such as the heart and the lungs. It consists of 12 pairs of ribs with their costal cartilages and the sternum. The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1-T12).
The sternum is the elongated bony structure on the anterior side of the thoracic cage. It consists of three parts: the manubrium, the body, and the xiphoid process.

Abdominal Aorta

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Summary

A rare thoracoabdominal teratoma, a germ cell tumor, was found in a patient. Surgical removal was necessary due to its size and location, despite being benign.

Area of Science:

Oncology
Surgical Pathology
Germ Cell Tumors

Background:

Teratomas originate from pluripotent germ cells and commonly occur in the ovaries.
While typically found in single locations, teratomas can exceptionally present in multiple body cavities.
This case highlights a rare instance of a teratoma spanning both the retroperitoneal and thoracic spaces.

Observation:

A 51-year-old female presented with acute low back pain, leading to the discovery of a large (12.5 x 18 cm) cystic retroperitoneal mass.
Computed tomography revealed a complex cystic formation with capsular visualization, compressing adjacent structures including the pancreas and left adrenal gland.
The mass extended through the diaphragm into the left thoracic cavity, indicating a thoracoabdominal presentation.

Findings:

Initial intervention involved cyst drainage and fenestration.
A subsequent radical surgical resection included splenectomy, left adrenalectomy, left nephrectomy, and removal of the tumor from the thoracic space.
Histopathological examination confirmed a mature teratoma, specifically a dermoid cyst, with skin-like morphology.

Implications:

This case underscores the importance of considering rare presentations of teratomas, even when benign.
The management of large, thoracoabdominal teratomas necessitates complex surgical strategies due to their extensive location and potential for organ displacement.
Complete surgical excision is crucial for definitive treatment, even in the absence of malignant transformation, to alleviate symptoms and prevent complications.
