Herniated Intervertebral Disc l: Introduction

Herniated Intervertebral Disc l: Introduction

Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Spinal Nerves: Plexus II

Spinal Nerves: Plexus II

The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Diverticular Disease of the Colon

Diverticular Disease of the Colon

Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...

Summary

This summary is machine-generated.

This case report details a rare instance where a lumbar pseudomeningocele, a fluid-filled sac near the spine, caused kidney swelling (hydronephrosis). Surgical intervention resolved the condition and associated pain.

Area of Science:

Neurosurgery
Urology
Radiology

Background:

Pseudomeningocele, often a complication of spine surgery, involves meningeal tears.
While typically self-healing or slowly enlarging, pseudomeningoceles rarely manifest as abdominal masses.
This study focuses on an exceptionally rare presentation of lumbar pseudomeningocele causing hydronephrosis.

Observation:

A patient with a history of extensive lumbar spine surgery developed a pseudomeningocele.
The pseudomeningocele presented as an abdominal mass, leading to ureteral compression.
This resulted in significant left-sided hydronephrosis.

Findings:

The patient experienced hydronephrosis of the left kidney secondary to the lumbar pseudomeningocele.
Surgical intervention successfully treated the pseudomeningocele and relieved ureteral obstruction.
Post-operative outcomes included resolution of hydronephrosis and improvement in flank, groin, and back pain.

Implications:

This case highlights an unusual etiology of hydronephrosis, emphasizing the importance of considering spinal complications.
It underscores the potential for pseudomeningoceles to present atypically as abdominal masses.
Early diagnosis and management of such rare presentations are crucial for preventing renal damage and alleviating pain.
