Summary
Oncogenic osteomalacia diagnosis was aided by nuclear imaging. Octreotide scintigraphy identified a parathyroid adenoma, suggesting somatostatin analogues as a potential treatment for receptor-positive cases.
Area of Science:
- Endocrinology
- Nuclear Medicine
- Oncology
Background:
- Oncogenic osteomalacia presents with bone pain and muscle weakness.
- Biochemical investigations suggested oncogenic osteomalacia in this patient.
- Nuclear imaging is crucial for localizing the underlying cause.
Purpose of the Study:
- To investigate the utility of whole-body bone scintigraphy and 111In-octreotide scintigraphy in a patient with suspected oncogenic osteomalacia.
- To evaluate the diagnostic accuracy of octreotide and parathyroid scintigraphy in identifying the source of the condition.
- To explore the potential of somatostatin analogues in managing somatostatin receptor-positive parathyroid adenomas.
Main Methods:
- Whole-body bone scintigraphy was performed to assess skeletal tracer uptake.
- 111In-octreotide scintigraphy was used to detect somatostatin receptor-positive lesions.
- Technetium-99m labeled methoxy-isobutyl-isonitryl (99mTc-MIB) parathyroid scintigraphy was conducted for localization.
- Histopathological examination confirmed the diagnosis after surgical resection.
Main Results:
- Bone scintigraphy revealed generalized marked skeletal uptake without focal pathology.
- Octreotide scintigraphy demonstrated octreotide accumulation in the left thyroid lobe region.
- 99mTc-MIB parathyroid scintigraphy confirmed radiotracer uptake at the same site.
- Histopathology confirmed a parathyroid adenoma.
Conclusions:
- Somatostatin receptor-positive parathyroid adenomas can exhibit octreotide uptake.
- Octreotide scintigraphy is a promising tool for identifying parathyroid adenomas.
- Somatostatin analogues may offer a potential medical treatment for somatostatin receptor-positive parathyroid conditions.

00:59The Parathyroid Glands
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...

01:17Hormones and Bone Tissue
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:29Positron Emission Tomography
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...
