Adnexal lesion has been a common issue in all the age groups, more common in reproductive age groups. Diagnosis of adnexal mass is difficult and complex, for, it may be benign or malignant, and it’s the risk of malignancy that propels for early, accurate and prompt diagnosis.
The aims of this study are as follows-
??? To assess the ability of MRI in diagnosis of sonographically indeterminate adnexal lesions.
??? To further characterize them in terms of content (solid, cystic, both solid-cystic), origin, tissue characterization (fat, blood, fibrous) and benign vs malignant potential.
??? To elucidate the sonographic imaging features leading to indeterminate diagnoses. MATERIALS AND METHODS
A prospective study, carried out from April 2016 to August 2016, under which 50 patients were selected, who were assessed Sonographically and diagnosed as indeterminate lesions using GE LOGIQ P5 machine, then, assessed by using SIEMENS MAGNETOM ESSENZA 1.5T MRI machine for characterization.
Determining the organ of origin is the essential first step in characterizing an adnexal mass, in our study, sonography performed below par in diagnosing the origin of the lesion. The second essential step of characterizing an adnexal lesion, is accurate tissue characterization, which was poor for sonography and excellent of MRI in our study. Thus, the study concludes, that MRI is an excellent modality for characterisation of adnexal lesions.
Adnexa is a complex structure, a significant proportion of adnexal masses detected by sonography are indeterminate. Sonography remains the initial imaging modality of choice in the assessment of the female pelvis, because it is readily available, inexpensive, safe and quick. Despite the high sensitivity of US, it is rarely specific. This study revealed that sonography performed poorly for determining the origin of the mass, which is the essential first step in characterizing an adnexal mass. MRI with its high contrast resolution & tissue characterization capabilities, helps in accurately resolving these uncertainties.
