Overview
- There are no other diagnostic studies associated with [disease name].
- [Diagnostic study] may be helpful in the diagnosis of [disease name]. Findings suggestive of/diagnostic of [disease name] include [finding 1], [finding 2], and [finding 3].
- Other diagnostic studies for [disease name] include [diagnostic study 1], which demonstrates [finding 1], [finding 2], and [finding 3], and [diagnostic study 2], which demonstrates [finding 1], [finding 2], and [finding 3].
Other Diagnostic Studies
- Other diagnostic studies for Riedel's thyroiditis include pathological and Immunohistochemical analysis.
Gross pathology
Gross pathology findings include:
- Pale thyroid mass
- No discernable tissue planes
Microscopic pathology
Microscopic pathology findings include:[1][2][3][4]
- Inflammatory cells infiltration
- Absence of giant cells, lymphoid follicles, oncocytes, or granulomas
- Fibrosis with hyalinization
- Extension of fibrosis outside the capsule
- Infiltration of plasma cells and lymphocytes in venular walls
Fine needle aspiration cytology
Fine needle aspiration cytology can lead to the misleading diagnosis due to fibrosis in Riedel thyroiditis. In most of the cases, it has no diagnostic value due to acellular or paucicellular smears.[5][6]Papi G, LiVolsi VA (2004). "Current concepts on Riedel thyroiditis". Am. J. Clin. Pathol. 121 Suppl: S50–63. PMID 15298150.</ref>
Immunohistochemical analysis
The immunohistochemical study in Riedel's thyroiditis is helpful to identify the inflammatory population of this form of thyroiditis. The findings include:[7][8][9][10]
- Predominance of T lymphocytes
- Presence of CD8+, CD4+ and plasma cells
- Presence of granulocytes and monocytes
- Strong positive stain to thyroglobulin
