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.

Cranial encephaloceles are rare conditions, which are more commonly seen in the anterior rather than in the middle cranial fossa. Temporal lobe encephalocele can present with a variety of clinical symptoms, amongst which include occult or symptomatic cerebrospinal fluid (CSF) fistula. We present a case of a patient with a short history of rhinorrhea who was found to have a CSF pool in the sphenoid sinus and right anteromedial temporosphenoidal encephalocele, which mimics sphenoid mucocoele, a much more common entity. This case highlights the imaging findings of temporosphenoidal encephalocoele and the diagnostic clues in differentiating this rare condition from the commoner mimics.
