MRI is helpful in the diagnosis of dermoid cyst. Findings on MRI suggestive of dermoid cyst include hypointense (due to the water content) or hyperintense (due to the presence of fatty secretions of [[sebaceous gland]]s) T1 signal, hyperintense T2 signal, and no enhancement or mild rim enhancement on contrast T1 signal.<ref name="pmid23590721">{{cite journal| author=Sanaullah M, Mumtaz S, Memon AA, Hashim AS, Bashir S| title=Intramedullary dermoid cyst with relatively atypical symptoms: a case report and review of the literature. | journal=J Med Case Rep | year= 2013 | volume= 7 | issue=  | pages= 104 | pmid=23590721 | doi=10.1186/1752-1947-7-104 | pmc=PMC3639845 | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=23590721  }} </ref><ref name=jn>Intracranial dermoid cyst.Radiopedia. http://radiopaedia.org/articles/intracranial-dermoid-cyst-1 Accessed on February 19, 2016</ref>

Overview

MRI is helpful in the diagnosis of dermoid cyst. Findings on MRI suggestive of dermoid cyst include hypointense (due to the water content) or hyperintense (due to the presence of fatty secretions of sebaceous glands) T1 signal, hyperintense T2 signal, and no enhancement or mild rim enhancement on contrast T1 signal.[1][2]

MRI

  • MRI is helpful in the diagnosis of dermoid cyst. Findings on MRI suggestive of dermoid cyst include:[1][2]

T1

  • Hypointense (due to the water content); or
  • Hyperintense (due to the presence of fatty secretions of sebaceous glands)

T2
