SERUM PHOSPHORUS Normal/Low/High

SERUM PHOSPHORUS

Method: UV Molybdate / Photometric Method

Parameter	Result	Units	Reference Range	Status
Serum Phosphorus	3.8	mg/dL	2.5 – 4.5	Normal

Clinical Significance

Phosphorus plays an important role in bone mineralization, energy metabolism, cell membrane integrity, and acid-base balance. Serum phosphorus levels are closely regulated by the kidneys, parathyroid hormone, and vitamin D.

Clinical Interpretation

• Serum phosphorus level is within normal physiological limits.
• No evidence of hypophosphatemia or hyperphosphatemia.
• Clinical correlation advised if renal, endocrine, or metabolic disorders are suspected.

Note: Reference ranges may vary depending on age, diet, renal status, and laboratory methodology. Clinical correlation is recommended. This report is not valid for medico-legal purposes.

Method: UV Molybdate / Photometric Method

Parameter	Result	Units	Reference Range	Status
Serum Phosphorus	1.9	mg/dL	2.5 – 4.5	Low

Clinical Significance

Phosphorus is essential for bone formation, cellular energy production, muscle and nerve function, and maintenance of acid-base balance. Low serum phosphorus levels (hypophosphatemia) may occur due to poor dietary intake, malabsorption, vitamin D deficiency, alcoholism, hyperparathyroidism, diabetic ketoacidosis recovery, or renal phosphate loss.

Clinical Interpretation

• Serum phosphorus level is below the normal reference range.
• Findings are suggestive of hypophosphatemia.
• Clinical correlation is advised with nutritional status, renal function, vitamin D levels, and parathyroid hormone status.
• Severe or persistent hypophosphatemia may be associated with muscle weakness, bone pain, fatigue, or metabolic disturbances.

Note: Reference ranges may vary depending on age, diet, renal status, and laboratory methodology. Clinical correlation is recommended. This report is not valid for medico-legal purposes.

Possible Causes of Hypophosphatemia

• Poor dietary intake or malnutrition
• Vitamin D deficiency
• Malabsorption syndromes / chronic diarrhea
• Hyperparathyroidism
• Chronic alcoholism
• Diabetic ketoacidosis recovery phase
• Renal phosphate wasting disorders
• Prolonged antacid use (aluminum/magnesium containing)
• Severe burns or sepsis
• Refeeding syndrome after prolonged starvation

Method: UV Molybdate / Photometric Method

Parameter	Result	Units	Reference Range	Status
Serum Phosphorus	5.8	mg/dL	2.5 – 4.5	High

Clinical Significance

Phosphorus plays an important role in bone mineralization, cellular energy production, muscle function, and acid-base balance. Elevated serum phosphorus levels (hyperphosphatemia) may result from impaired renal excretion, endocrine disorders, excessive phosphate intake, or cellular breakdown. Persistent elevation may contribute to soft tissue and vascular calcification, especially in patients with chronic kidney disease.

Clinical Interpretation

• Serum phosphorus level is above the normal reference range.
• Findings are suggestive of hyperphosphatemia.
• Correlation with renal function tests, calcium levels, parathyroid hormone, and vitamin D status is advised.
• Persistent hyperphosphatemia may require further evaluation to identify underlying renal, endocrine, or metabolic causes.

Note: Reference ranges may vary depending on age, diet, renal status, and laboratory methodology. Clinical correlation is recommended. This report is not valid for medico-legal purposes.

Possible Causes of Hyperphosphatemia

• Chronic kidney disease / renal failure
• Hypoparathyroidism
• Excessive vitamin D therapy or phosphate intake
• Tumor lysis syndrome or rhabdomyolysis
• Metabolic or diabetic ketoacidosis recovery phase
• Hemolysis or severe tissue breakdown
• Certain medications or phosphate-containing laxatives/enemas

SCRS Topic Header

Deep Paraspinal Intramuscular Lipoma – Back Lump (Dorsal Wall Ultrasound)

Deep Musculoskeletal (Paraspinal) Ultrasound Case Study Case Study No: R-22

Dorsal Wall Ultrasound

Technique: Real-time ultrasound examination of the posterior lumbar dorsal wall was performed using a high-frequency linear transducer (7–12 MHz), supplemented with a low-frequency curvilinear probe where required for deeper evaluation. Systematic assessment of the paraspinal region was performed in longitudinal and transverse planes. Skin, subcutaneous tissue, paraspinal muscle layers, and deeper soft tissue structures were evaluated.
Clinical indication: Suspected soft tissue lesion

Skin & Subcutaneous Tissue: Skin thickness appears normal. Subcutaneous tissue shows normal echotexture with no edema or collection.

Muscle Layers: In the posterior lumbar paraspinal region, a well-defined hyperechoic lesion is noted within the deep paraspinal muscle plane (likely involving erector spinae / multifidus group), measuring approximately 4.3 × 2.0 cm.
The lesion demonstrates homogeneous fatty echotexture with fine internal linear echogenic striations, oriented parallel to muscle fibers. No surrounding muscle invasion or architectural distortion is identified. Fascial Planes: Fascial planes appear preserved with no evidence of disruption or fluid tracking. Soft Tissue: No additional focal soft tissue mass, cystic lesion, or abscess is seen. Vascularity: No internal vascularity is noted within the lesion on Doppler evaluation.

Impression: Well-defined intramuscular hyperechoic lesion within the deep paraspinal muscles, demonstrating characteristic sonographic features of a lipoma.
Features are suggestive of deep paraspinal intramuscular lipoma.

Recommendation: Clinical correlation is advised. MRI may be considered for further evaluation, particularly to assess depth and extent. Follow-up is recommended if symptomatic or showing interval increase in size.

Kindly Note:

Limitations / Technical Factors:
Ultrasound evaluation is limited for deep-seated lesions and bony structures.
Clinical correlation and further imaging (MRI / CT) may be required depending on clinical suspicion.

Declaration:
I, R. K. Mouj, declare that the material presented in this case study titled “Deep Paraspinal Intramuscular Lipoma – Dorsal Wall (Back Lump) on Ultrasonography (USG)” has been prepared solely for educational and academic purposes. The findings demonstrate a well-defined, hyperechoic lesion located within the deep paraspinal muscle plane (erector spinae / multifidus group) in the posterior lumbar region, consistent with an intramuscular lipoma. The lesion shows homogeneous fatty echotexture with fine internal linear striations, oriented parallel to muscle fibers, with absence of internal vascularity on Doppler imaging. No surrounding soft tissue infiltration or aggressive features are identified. Ultrasonography is a useful, non-invasive modality for evaluating soft tissue masses; however, assessment of deep lesions may be limited, and further imaging such as MRI may be required.
