Idiopathic Midline Granuloma: Sensitivity and Specificity

Introduction: None written.

The sensitivity and specificity of findings for Idiopathic Midline Granuloma are listed below. See the left navigation bar to change the display.

Pre-Test Probability (Prevalence): %.	Post-Test Probability (Predictive Value): %.	Switch to display mode.
Note that calculating probabilities from more than one** finding is inherently inaccurate because findings are not independent. (For example, using two positive findings that share a common pathogenesis is likely to overestimate the true probability.)

Findings With Unspecified Accuracy
Finding	Result	Sensitivity	Specificity
[ + ] Hard palate erosion		No accuracy specified.
Hard palate erosion causing perforation can be seen in idiopathic midline granuloma and midline malignant reticulosis. This finding is not expected in Wegener's granulomatosis Study: PMID 6336643 See page 78 of: Fauci AS, Haynes BF, Katz P, Wolff SM. Wegener's granulomatosis: prospective clinical and therapeutic experience with 85 patients for 21 years. Ann Intern Med. 1983 Jan;98(1):76-85. Review.
