This study characterizes the magnetic resonance imaging features of umbilical endometriosis in two patients, one with a history of laparoscopy and another with an umbilical hernia. Researchers performed MR imaging using body and spine coils to visualize the lesions, which were subsequently surgically removed for histologic correlation. The findings demonstrated that MRI effectively delineated lesion size and location while identifying signs of prior hemorrhage consistent with endometriosis, thereby excluding intraabdominal extension. This paper is centrally about endometriosis — specifically the radiological presentation and diagnostic utility of MRI for extra-pelvic umbilical involvement.

Abstract

OBJECTIVE: We describe the MR appearance of endometriosis involving the umbilicus in two patients. One patient had a history of laparoscopy performed through the umbilicus; the other had an umbilical hernia. MATERIALS AND METHODS: MR imaging was performed using both a body coil and a spine coil (with the patient lying prone on the spine coil). The lesions were surgically removed and their MR appearance was correlated with the results of histologic analysis. RESULTS: The lesions were well delineated on MRI and showed evidence of prior hemorrhage consistent with endometriosis. Both lesions were shown to be endometriosis at surgical pathology. CONCLUSION: MR imaging was useful for delineating the size and location of the lesions and excluding intraabdominal extension.

Objective

We describe the MR appearance of endometriosis involving the umbilicus in two patients. One patient had a history of laparoscopy performed through the umbilicus; the other had an umbilical hernia.

Materials and methods

MR imaging was performed using both a body coil and a spine coil (with the patient lying prone on the spine coil). The lesions were surgically removed and their MR appearance was correlated with the results of histologic analysis.

Results

The lesions were well delineated on MRI and showed evidence of prior hemorrhage consistent with endometriosis. Both lesions were shown to be endometriosis at surgical pathology.

Conclusion

MR imaging was useful for delineating the size and location of the lesions and excluding intraabdominal extension. Copyright © Lippincott-Raven Publishers.
