Insights

Homocystinuria, a metabolic disorder, can manifest as a calcified right atrial mass. This rare presentation highlights unusual imaging findings in a patient evaluated for respiratory infection.

Area of Science:

  • Cardiology
  • Metabolic Disorders
  • Genetics

Background:

  • Homocystinuria is an inherited metabolic disorder caused by cystathionine β-synthase deficiency.
  • This deficiency leads to elevated homocysteine and methionine, and reduced cysteine levels.
  • These biochemical changes increase the risk of arterial and venous thromboembolism.

Observation:

  • A case of homocystinuria presented with a calcified right atrial mass.
  • The patient was initially evaluated for a lower respiratory tract infection.
  • Unusual imaging findings were observed using multiple detector computed tomography and radiographs.

Findings:

  • The study identifies a rare association between homocystinuria and a calcified right atrial mass.
  • Imaging modalities revealed a unique combination of diagnostic features.
  • This case underscores the diverse clinical manifestations of homocystinuria.

Implications:

  • This case expands the understanding of cardiac manifestations in homocystinuria.
  • It highlights the importance of considering metabolic disorders in patients with unexplained cardiac masses.
  • The findings emphasize the utility of advanced imaging in diagnosing rare conditions.

Atomic Mass

Atoms — and the protons, neutrons, and electrons that compose them — are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which...

Molar Mass

The identity of a substance is defined not only by the types of atoms or ions it contains but by the quantity of each type of atom or ion. For example, water, H2O, and hydrogen peroxide, H2O2, are alike in that their respective molecules are composed of hydrogen and oxygen atoms. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule, which has only one, the two substances exhibit very different properties.

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Mass and Weight01:19

Mass and Weight

Mass and weight are often used interchangeably in everyday conversation. For example,  medical records often show our weight in kilograms, but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of the Earth on an object. It depends on the distance from the center of the Earth. Weight dramatically varies if we leave the Earth's surface, unlike mass, which does not vary with location. On the Moon, for example, the...

Atomic Number and Mass Number01:12

Atomic Number and Mass Number

The number of protons in the nucleus of an atom is its atomic number (Z). This is the defining trait of an element. Its value determines the identity of the atom. For example, any atom that contains six protons is the element carbon and has the atomic number 6, regardless of how many neutrons or electrons it may have. A neutral atom must contain the same number of positive and negative charges, so the number of protons equals the number of electrons. This means that the atomic number also...
