Abstract

Introduction:

Juxta-facet cysts (JFCs) are extradural lesions. Calcification of cyst walls is often reported, although completely calcified facet cysts are extremely rare.

Case Presentation:

A 65-year-old man presented with a 1-year history of the right lower extremity weakness and pain, and chronic low back pain. Imaging showed hypointensity on T1- and T2-weighted magnetic resonance images which can be very well appreciated on a completely calcified computed tomography mass arising from the right L3/4 facet joint. The patient underwent a total cyst removal with a facetectomy of the right L3/4 facet, and L3 to L4 posterior fusion.

Conclusion:

We presented a case of a completely calcified JFC in a patient with back pain and radiculopathy who underwent cystectomy and spinal fusion. JFCs should be considered in the differential diagnosis of calcified extradural lesions.

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

Urinary Tract Calculi III: Medical Management

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
