Summary
A cystic mass near the pancreas tail was diagnosed as an accessory spleen. Histopathology confirmed spleen-like tissue despite infarction, explaining the patient's pain.
Area of Science:
- Gastroenterology and Hepatology
- Surgical Pathology
- Abdominal Imaging
Background:
- Left upper quadrant pain in a 37-year-old woman prompted medical evaluation.
- Imaging revealed a 70 mm cystic mass adjacent to the pancreatic tail and spleen hilum.
Observation:
- The mass exhibited a distorted fascicular structure.
- Surgical exploration identified this structure as connective tissue with vessels.
Findings:
- Histopathological examination revealed spleen-like stroma within the cystic mass.
- Degeneration due to infarction was noted, leading to a strong suspicion of an accessory spleen.
Implications:
- This case highlights the importance of considering accessory spleens in the differential diagnosis of pancreatic and splenic masses.
- Understanding the potential for infarction in accessory spleens is crucial for accurate diagnosis and management.

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
