Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Synthesis and Functions of Calcitonin

Synthesis and Functions of Calcitonin

Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Peripheral Artery Disease I: Introduction

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Urinary Tract Calculi I: Introduction

Urinary Tract Calculi I: Introduction

Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

Atherosclerosis I: Introduction

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Summary

Solitary tumorous calcification can cause carpal tunnel syndrome. Surgical release of these calcifications, often composed of basic calcium phosphate, provides a treatment option.

Metacarpal Small Incision for Carpal Tunnel Syndrome

Metacarpal Small Incision for Carpal Tunnel Syndrome

Published on: April 5, 2024

Area of Science:

Orthopedics
Hand Surgery
Radiology

Background:

Carpal tunnel syndrome (CTS) is commonly caused by median nerve compression.
Solitary tumorous calcification as a cause of CTS is rarely documented in medical literature.

Purpose of the Study:

To describe the clinical experience with surgically treated cases of solitary tumorous calcification causing carpal tunnel syndrome.
To investigate the characteristics and composition of these calcified masses.

Main Methods:

A retrospective review of seven patients surgically treated for CTS due to tumorous calcification.
Analysis of preoperative radiographic findings, operative records, and histological and compositional analysis of removed calcifications.

Main Results:

Calcified masses were located anterior to the capitate bone within the carpal tunnel.
The calcified nodules measured between 10x10x10 mm and 18 mm, attached to the palmar radiocarpal extrinsic ligament.
Composition analysis revealed an average of 60% basic calcium phosphate; histology showed calcified deposits with fibrocartilaginous tissue in three cases.

Conclusions:

The findings suggest a reactive process, similar to calcifying tendinitis, may underlie tumorous calcification causing CTS.
Surgical intervention is a viable treatment for this rare cause of carpal tunnel syndrome.
