Introduction: Accessory spleen is an abnormality represented by ectopic splenic tissue detached from the main body of the spleen. Torsion is a possible complication and it occurs exceptionally. Clinically it is characterized by a nonspecific acute or recurrent abdominal pain.
Case: A 12 years old female with recurrent abdominal pain and palpable mass on her left iliac fossa, that has been noticed a month before consultation. At the emergency service she was checked and complementary exams were requested.
US: In the left iliac fossa it was found a solid, rounded formation, with well-defined edges, which moved when the patient changed her position. It showed positive Doppler examination except for a focal hypoechogenic area, which was not vascularized. The structure reminded the spleen echogenicity.
CT: normal spleen parenchyma, shape and edges. At left iliac fossa, next to the lower pole of the kidney, a rounded well-defined image which showed heterogeneous EV enhancement with no opacification of the lower corner due to ischemia areas was seen. This image had a vascular hilum that connected to the main spleen vascular hilum. Further images where taken changing the patient position, where the movement of the mass was corroborated.
As a result of this exams we realized that the recurrent abdominal pain of the girl was due to an ectopic spleen that has been torsioned - detorsioned several times.
Conclusions: Usually, accessory spleen is asymptomatic. Torsion and infarction, rupture with bleeding, and infection with abscess are a very rare complications. Intermittent torsion-detorsion may produce recurrent episodes of abdominal pain caused by short-lasting ischemia of the accessory spleen or from direct mechanical irritation of surrounding organs.
To sum up, torsion of an accessory spleen is extremely rare and is still a diagnostic dilemma. So we should consider this any time a patient with abdominal pain (acute or recurrent) comes to us and other diagnosis failed to explain it. Read More

Learning Objective: This educational exhibit will review a variety of pediatric splenic lesions and their appearance on various specific multimodality imaging finding as seen on ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI). This exhibit will also review an algorithm to approaching non-cystic splenic lesions in pediatrics. Read More

While the most common abnormalities of the spleen are splenomegaly and trauma, many additional disease states can be manifested in the spleen which should be considered when evaluating the abdomen on cross sectional imaging. We composed a pictorial guide of a wide variety of variants and diseases for education and reference.

The spleen is rarely the first organ to come to mind in discussing pathology of the abdomen, and indeed may often be the last. However, there are a multitude of splenic processes and abnormalities that should be kept in mind when discussing the pediatric abdomen. Additionally, splenic abnormalities, or lack thereof, can also be clues to diagnosis in more difficult cases. Read More

In a child the abdominal organs are more at risk from blunt injury, the reasons for this include the fact that the organs are relatively more anterior and inferior and lie inferior to the ribs rather than behind them as in an adult. Additionally, paediatric ribs are cartilaginous and so although rib fractures are less likely, compressive injuries secondary to the relative elasticity of the rib cage are far more common. The computed tomography (CT) features of abdominal visceral injury include lacerations, subcapsular or parenchymal haematomas, active haemorrhage, and vascular injuries, all of which the radiologists must be familiar with. Although there is an increasing trend toward non-operative management of abdominal solid organ injury, radiologists must also be aware of the key imaging features that suggest the need for surgical or interventional radiology input.

Based on our experience as one of the largest Level 1 trauma centres in Europe, the aims of this educational exhibit are to:
(i) Provide a pictorial review the spectrum of findings in blunt injury to the liver, kidneys and spleen as demonstrated on CT.
(ii) Discuss the role of Interventional Radiology in cases of associated vascular injury. Read More
