| Introduction|| |
Splenic torsion is a rare condition happening due to the weakening or malformation of the splenic ligaments and is mostly seen in children and young women. It is usually associated with the wandering spleen disease. Whereas, in the present case, the spleen was in its normal anatomical position which is exceedingly rare and is mentioned in only one case report. Lack of symptoms except abdominal pain may lead to difficulty in diagnosis of torsion. This issue may be more applicable to patients with partial splenic torsion in normal anatomical position, like in the present case. Early surgical intervention is crucial for prevention of splenic infarction.
| Case Report|| |
A 20-year-old female presented with complaints of severe left upper quadrant pain of 3 days duration, intermittently radiating toward the left lower quadrant. She did not declare history of trauma or injury. She had repeatedly vomited nonbloody, nonbilious fluid. Bowel opening was regular. She was admitted to the different emergency services and treated with nonsteroidal anti-inflammatory drugs, but as seems, the pain was not relieved.
Laboratory studies showed only high C-reactive protein levels (1467 mg/L). She had a history of using contraceptives but stopped to take this medicine 2 years ago. She also had a history of asthma and peptic ulcer.
Management and outcome
The patient had been consulted to radiology department. On abdominal ultrasound (US), the spleen was found in its normal anatomic position and Doppler US examination revealed that there is no blood flow in splenic vein [Figure 1]a.

A contrast-enhanced computed tomography (CT) scan was also performed. Portal-phase CT images showed hypoperfused spleen, patent splenic artery, and contrast in proximal splenic vein but no contrast filling in distal part. There was no thrombus in splenic vein [Figure 1]b. Delayed-phase CT images revealed a patent splenic vein [Figure 1]c. These data showed that the partial torsion of spleen caused the splenic vein obstruction.
The patient underwent laparoscopic operation and detorsion of spleen was performed. Because of the shortness of the pedicle of the spleen, splenopexy could not be performed [Figure 2]. Postoperative Doppler US examination confirmed patency of splenic vein. At the first postoperative follow-up after 1 month, the patient was evaluated as normal. The patient did not come to the next follow-up.

| Discussion|| |
The spleen is hold in its normal position by the gastrosplenic and splenorenal ligaments. While the former one connects the greater curvature of the stomach to the ventral aspect of the spleen, the latter attaches the spleen to the posterior abdominal wall.
Inadequate development of these ligaments resulting in a long splenic mesentery and acquired factors such as abdominal wall laxity, the hormonal effects of pregnancy, and splenomegaly may increase splenic mobility.
A wandering spleen or splenic ptosis is defined as a migration of the spleen from its anatomic location in anywhere in the abdomen or pelvis.
Normally located spleen with ligamentous laxity as wandering spleen is usually asymptomatic. Torsion, a complication of wandering spleen, makes the situation symptomatic. Torsion of wandering spleen is a relatively rare clinical occurrence with about 500 cases reported and an incidence of < 0.2%. It is fifteen times more common in females, usually detected between 20 and 40 years of age.
Serious and constant abdominal pain suggests splenic torsion and secondary ischemia due to compromise in venous outflow, which produces congestion and impairment of arterial inflow. Pain appears as a result of both stretching in splenic capsule with rapid splenic enlargement and local peritonitis.
To the best of our knowledge, only one case with torsion of a spleen located in a normal anatomical position has been reported in the literature to date. The patient in the referred case underwent an urgent laparotomy and splenectomy for 360° torsion of her spleen. Hence, the present case is unique because the 180° torsion occurred in normal anatomical position of spleen.
Ultrasonography and CT are key elements in diagnosing because physical symptoms and laboratory data are nonspecific.
In the present case, no flow could be detected in the splenic vein [Figure 1]a. Splenic parenchyma was normal on gray scale imaging. Only arterial flow could be detected in the splenic hilus and parenchyma. We performed a contrast-enhanced CT scan to rule out splenic vein thrombosis [Figure 1]b and [Figure 1]c.
The presence of blood flow in proximal splenic vein segments could be explained with the tributary veins, namely inferior mesenteric vein or varices due to chronic venous congestion joining the main splenic vein proximal to the torsion.
Preservation of the spleen with laparoscopic splenopexy is highly recommended to avoid recurrence of torsion and complication of splenectomy.
| Conclusion|| |
Splenic torsion is relatively rare pathology and is usually found in wandering spleen cases. Partial splenic torsion occurring in normal anatomic position is more rare, and to diagnose of such torsion is more difficult even when it becomes symptomatic. A delay in diagnosis could lead to serious consequences, including splenectomy. The possibility of the splenic torsion in its normal anatomic position should come to mind in cases with sharp and persistent left upper abdominal pain, especially in cases without diagnosis, when there are not any other explanations. Laparoscopic splenopexy is an excellent option for organ-preserving treatment in splenic torsion. Doppler US is indispensable diagnostic method in such cases.
