Overview
There are no CT scan findings associated with [disease name].
OR
[Location] CT scan may be helpful in the diagnosis of [disease name]. Findings on CT scan suggestive of/diagnostic of [disease name] include [finding 1], [finding 2], and [finding 3].
OR
There are no CT scan findings associated with [disease name]. However, a CT scan may be helpful in the diagnosis of complications of [disease name], which include [complication 1], [complication 2], and [complication 3].
CT scan
CT scan findings in autoimmune polyendocrine syndrome (APS) depends upon the subtype of APS and the organ involved. In APS type 1, parathyroids and adrenal glands are often involved and may present with:
- CT scan of the abdomen may be helpful in the diagnosis of autoimmune polyendocrine syndrome (APS) type 1. Findings on CT scan suggestive of adrenal insufficiency as seen in APS include:
- Small adrenal remnants bilaterally suggestive of autoimmune adrenalitis.
- Chronic cases of APS may have dense calcification in one or both adrenal beds.
- Atrophic adrenal glands - in idiopathic autoimmune Addison's disease.
- Peripheral quantitative computed tomography (pQCT) may be helpful in the diagnosis of hypopparathyroidism.[1][2]
- Findings on pQCT scan suggestive of hypoparathyroidism include:
- Increase in volumetric bone mineral density (vBMD) of both cortical and trabecular bones.
- Increase in bone mineral density (BMD) of both cortical and trabecular bones.
