Summary
A rare case of a herniated lumbar disc fragment migrating to the psoas muscle is presented. Correct diagnosis is crucial to prevent misdiagnosis and inappropriate treatment for this confusing radiographic presentation.
Area of Science:
- Spinal surgery
- Radiology
- Orthopedic surgery
Background:
- Lumbar disc herniation can present with confusing radiographic findings when fragments migrate.
- Extruded disc fragments may move away from the spinal column, complicating diagnosis.
Observation:
- A rare case of a sequestrated lumbar disc fragment within the psoas muscle is detailed.
- The fragment was separate from the adjacent disc space.
- Imaging studies mimicked a psoas abscess.
Findings:
- Radiographic features of migrated disc fragments can be misleading.
- Psoas muscle involvement by disc fragments is an uncommon presentation.
Implications:
- Accurate diagnosis of migrated disc fragments is essential.
- Avoiding unnecessary treatments like antibiotics or surgical drainage for presumed abscess is vital.
- Appropriate management prevents patient harm and optimizes outcomes.

Appendicitis
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...
Appendicitis-I: Introduction
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...
