Endometriosis is defined as the presence of functional endometrial tissue outside the endometrial cavity and myometrium. Although this is a frequent disease with multifactorial causes, involvement of the lower urinary tract is rare. Magnetic resonance imaging is highly sensitive, specific and accurate in the diagnosis of endometriosis in the lower urinary tract, especially for allowing the identification of lesions obscured by adhesions or with subperitoneal extension. The present iconographic essay presents the main magnetic resonance imaging findings of the lower urinary tract involvement by endometriosis.

Magnetic resonance imaging plays a relevant role in the assessment of patients with pain on the dorsal aspect of the distal forearm and wrist. Among the causes of pain, intersection syndrome is highlighted, corresponding to an inflammatory process affecting the tendons of the second compartment of the forearm extensor (extensor carpi radialis brevis and extensor carpi radialis longus), usually caused by direct trauma or repetitive activities requiring wrist flexion and extension. The present essay is aimed at illustrating the typical findings in intersection syndrome of the forearm and discuss the main differential diagnoses.
