Summary
Large psoas abscesses can spread to thigh muscles even after initial drainage. Open surgical drainage combined with antibiotics is crucial for effective treatment and recovery.
Area of Science:
- Medical imaging and interventional radiology
- Infectious disease management
- Surgical pathology
Background:
- Psoas abscess, a rare pyomyositis of the psoas muscle, presents insidiously, challenging diagnosis and potentially leading to poor prognosis.
- While psoas abscesses can extend down the sheath to the thigh, involvement of thigh adductors is infrequent.
- The current incidence of psoas abscesses is not well-established.
Observation:
- A 45-year-old male presented with left thigh pain and limited hip/knee movement.
- Initial percutaneous drainage of a psoas abscess provided temporary relief, but the abscess later extended to involve the thigh adductors.
- Open surgical drainage of the flank and thigh, along with antibiotics, led to complete resolution.
Findings:
- Large psoas abscesses can penetrate the psoas sheath and descend into the thigh adductors, even after percutaneous drainage.
- Recurrence or extension of psoas abscesses into the thigh necessitates further intervention.
Implications:
- Prompt and comprehensive surgical intervention, including open drainage, is vital for managing extensive psoas abscesses.
- Effective antibiotic therapy is essential in conjunction with surgical management for optimal patient outcomes.
- This case highlights the importance of considering advanced imaging and surgical approaches for complex psoas abscess presentations.

01:20Muscles that Move the Thigh
The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar fascia...

01:22Appendicitis-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...

01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:23Muscles that Move the Leg
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...

01:21Muscles of the Abdomen
The abdominal wall encircles the abdominal cavity, providing flexible protection and shielding the internal organs from harm. It is bordered at the top by the xiphoid process and costal margins, at the back by the vertebral column, and at the bottom by the pelvic bones and inguinal ligament. The abdominal wall is divided into two regions — the anterolateral and posterior regions.
Anterolateral Region
The anterolateral region comprises five paired muscles classified into the lateral and anterior...

01:28Acute Pyelonephritis II: Diagnostic Studies and Management
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
