7. The classical presentation is an unilocular cyst
containing low-level, homogeneous "ground-glass" like
internal echoes, as a result of the hemorrhagic debris and
no vascularity on colour doppler
• multiple locules (~85% will have <5 locules)
• hyperechoic wall foci (present in 35%) due to cholesterol
deposits
• cystic-solid lesion (~15%) or purely solid lesion (1%)
• anechoic cysts (rare: 2%)
• fluid-fluid level

11. T1
• lesions appear hyperintense while acute hemorrhage occasionally appears
hypointense
• endometriomas with high T1 signal characteristically do not show loss of signal
on T1 fat-suppressed sequences, which is important for differentiating it from a
mature cystic teratoma of the ovary
T2
• Typically hypointense owing to the presence of deoxyhemoglobin and
methemoglobin (shading sign), which is very suggestive of an endometrioma
• T2 dark spot sign is specific for chronic hemorrhage and is helpful in diagnosing
endometriomas
