Inguinal swelling is a common presenting complaint to the surgical clinic. However, among the list of differential diagnoses, Canal of Nuck (CON) cyst, which is rare, is not usually considered and can lead to delayed or misdiagnosis. We report the case of a healthy 41 -year-old woman with a short history of left inguinal swelling initially thought to be an inguinal hernia. Ultrasound showed a unilocular avascular cystic lesion with posterior acoustic enhancement, with no peritoneal cavity communication. Computed tomography scan confirmed the presence of a well -defined, non - enhancing, thin-walled encysted lesion anteromedial to the left common femoral vessels. Surgery confirmed the presence of a CON cyst. It is a rare developmental disorder, especially in the adult female population and should be considered as a differential diagnosis for groin swelling. Imaging can help establish a diagnosis prior to surgery.

In central venous obstruction, vertebral marrow enhancement (VME) may be seen secondary to collateral venous flow via the vertebral venous plexus. 1 There are only sporadic case reports on pseudolesions due to collateral enhancement mimicking sclerotic osseous metastasis. This abnormal vertebral enhancement may lead to erroneous diagnosis of sclerotic metastases or suspicious bone lesion which affect the management and prognosis. We describe a case of brachiocephalic vein obstruction-related vertebral body pseudolesions as identified in contrast-enhanced computed tomography (CECT) scan
