A case of myxoid adrenocortical neoplasm: computed tomography and magnetic resonance imaging characteristics.

[adrenal incidentaloma]

Myxoid adrenocortical neoplasms are rare; to our knowledge, only 56 cases have been reported in the literature. Therefore, distinguishing benign from malignant cases is challenging. Although the histopathological features of myxoid adrenocortical neoplasia have been amply demonstrated, their imaging characteristics are yet to be reported. We describe here these characteristics for such a neoplasm. Our patient, a 70-year-old male, was found to have a 3-cm left adrenal incidentaloma through a non-enhanced computed tomography. Attenuation measurements were 22 Hounsfield units on precontrast imagery, and percentage enhancement washout was 92%. Magnetic resonance imaging showed no loss of signal intensity in T1-weighted out-of-phase images, but high signal intensity on T2-weighted and diffusion-weighted images. Left adrenalectomy was performed and the pathological diagnosis was confirmed as myxoid adrenocortical neoplasm. The imaging characteristics reported here will be beneficial to the differential diagnosis of myxoid adrenocortical neoplasms based upon image analysis and will help distinguish benign from malignant neoplasms.
