Author(s) :
Taco Geertsma, MD
 
Presentation Four weeks old girl with a palpable mass in the right groin
 
 
 
Caption: Detail of the palpable mass
Description: The image shows a solid lesion with tiny cystic structures. The small cysts are the follicles in a normal ovary
 
 
 
Caption: Longitudinal view of the groin
Description: This longitudinal view of the groin shows an intrabdominal extension of the lesion consistent with an inguinal hernia
 
 
 
Caption: Transverse view of the groin
Description: The Transverse view of the groin shows an intrabdominal extension of the lesion consistent with an inguinal hernia
 
 
 
Caption: Color Doppler image of the lesion
Description: This color doppler image shows the normal vascularity of the right ovary
 
 
 
Caption: Transverse image with color Doppler of the lesion
Description: This color doppler image shows the normal vascularity of the right ovary. Also flow in the epigastric artery and vein (round vessels) can be identified. The vessels entering the hernia run lateral to the epigastric vessels. This means it is a lateral or indirect inguinal hernia
 
Differential Diagnosis Differential diagnosis of a palpable mass in girls are
- Nuck cyst or hydrocele.
- Inguinal lymphe node
- Inguinal hernia.
- Soft tissue tumors
 
Final Diagnosis nonreducible inguinal hernia containing the right ovary
 
Discussion

A Nuck cyst or hydrocele is a  cystic non vascularized lesion in a typical location.

Inguinal lymphe nodes are solid structures although necrosis or abscess formation can result in cystic areas. They are often multiple and show no intra abdominal extension.

Inguinal hernia. Inguinal hernias can be differtiated accordind to
  Location:  in a medial (direct)  or lateral (indirect ) inguinal hernia
  Effect of compression:  Reducible or nonreducible inguinal hernia
  Contents: Fluid, fat bowel ovary or other abdominal structures

Other soft tissue tumors benign (like lipomas) or malignat (like sarcomas) in a very young girl are rare but must be considered in any case of a solid mass. In some cases necrosis in a tumor can mimick a cystic lesion.
