Magnetic Resonance Imaging Guided High Intensity Focused Ultrasound is a Non-Invasive Treatment Modality for Patients with Abdominal Wall Endometriosis

Two women (29 and 35 years of age) presented with an abdominal wall mass in close proximity to a cesarean scar. The main complaints consisted of pain at the site of the mass with catamenial exacerbations. Clinical and imaging findings were consistent with abdominal wall endometriosis in both cases. First, hormonal treatment was started, which proved unsuccessful. Typically, at this point, the proposed treatment would be wide surgical excision. Alternatively, magnetic resonance imaging–guided high-intensity focused ultrasound treatment was offered with the goal to diminish pain complaints noninvasively. Upon treatment, both patients’ complaints diminished although some cyclic pain persisted. Overall, these cases show that magnetic resonance imaging–guided high-intensity focused ultrasound can be used as a noninvasive treatment method to reduce complaints in patients with abdominal wall endometriosis.
