Wandering spleen with torsion: a rare cause of acute abdomen in a 14-year-old girl

Splenic torsion mistaken for an ovarian cyst: a case report

BACKGROUND

Wandering spleen (or ectopic spleen) refers to a hyper-mobile spleen resulting in its displacement from the normal anatomical position to usually in the lower abdominal or pelvic cavity. While ultrasound is often the first radiological modality used, Computed Tomography (CT) shows a clear picture and aides to reach a diagnosis. In circumstances where appropriate imaging modalities are not available, or the operator is inexperienced, diagnosis of wandering spleen can be missed.

CASE PRESENTATION

A 22-nulligravida unmarried Sindhi female had presented to the Emergency Room (ER) with a 5-day history of intermittent severe lower abdominal pain. An ultrasound at a local practitioner had suggested an ovarian cyst. Ultrasound-pelvis and later CT scan at our facility reported an enlarged wandering spleen with torsion of its pedicle and infarction. Exploratory laparotomy with splenectomy was done. An enlarged wandering spleen was found with torsion of the splenic vein and thrombosed arterial supply from omentum wrapped over the mass. The patient developed thrombocytosis post-surgery but otherwise did well and was discharged after 2 days.

CONCLUSION

Splenic torsion secondary to a wandering spleen can be challenging to diagnose, especially in resource limited settings where ultrasound might be the only modality available. Timely diagnosis and proper intervention are key to saving the life and the spleen.

Spleno-Sigmoid Knotting - An Unfamiliar Cause of Intestinal Obstruction

INTRODUCTION

Spleno-sigmoid knotting is the twisting of the spleen around the sigmoid colon, causing obstruction of the sigmoid colon. It is an uncommon cause of intestinal obstruction. To our knowledge, there has been no previous case report of spleno-sigmoid knotting before our case.

CASE REPORT

Here, we present the case of an 18-year-old female patient who visited the surgical emergency outpatient department with diffuse and progressive abdominal pain lasting for one and a half days. She also experienced obstipation and frequent episodes of vomiting of ingested matter. Upon initial evaluation, she exhibited tachycardia and tachypnea, and her abdomen was grossly distended with diffuse direct and rebound tenderness. Further investigation revealed significant leukocytosis with neutrophil predominance. Emergency laparotomy was performed with a possible diagnosis of generalized peritonitis secondary to gangrenous sigmoid volvulus, which revealed gangrenous spleno-sigmoid knotting.

DISCUSSION

Various types of intestinal knots have been reported, with ileo-sigmoid knots being the most common and ileo-ileal knots being the rarest. Wandering spleen is a rare congenital anomaly with a variable clinical presentation ranging from asymptomatic to mild abdominal pain or acute abdomen due to torsion or acute pancreatitis. It can also cause intestinal obstruction, which may be the initial presentation.

CONCLUSION

In patients presenting with acute abdominal pain and features of bowel obstruction, the possibility of spleno-sigmoid knotting should be considered, and early intervention should be instituted to prevent gangrenous progression and sepsis.

A case of symptomatic intramesenteric accessory spleen: The diagnostic role of contrast-enhanced ultrasound

Introduction

Accessory spleen is a congenital defect characterised by a separated ectopic splenic parenchyma usually located in the splenic hilum and the tail of the pancreas. It is present in about 10%-30% of the population and, generally, does not cause any symptoms.

Case report

We report an interesting case of a woman with symptomatic intramesenteric accessory spleen detected and characterised by contrast-enhanced ultrasound. The patient experienced a long history of intermittent pain in the left upper abdomen. The diagnosis was confirmed by post-operative pathology examination.

Discussion

Accessory spleen usually appears as a well-circumscribed ovoid mass, 1-3 cm in diameter, infrequently located in the mesentery. It may rarely become symptomatic because of complications. Diagnosis of this condition as a cause of abdominal is difficult and rarely has been made pre-operatively. Computed tomography and magnetic resonance imaging might help, but they should be performed with intravenous contrast injection, and they cannot provide direct evidence between the pain of the patient and the lesion. Conversely, real-time ultrasound can assess and diagnose the lesion showing the exact correspondence with abdominal pain of the patient. Furthermore, ultrasound and contrast-enhanced ultrasound are widely available, safe and relatively inexpensive.

Conclusion

Apart from the rarity of this condition, this case report demonstrates the ability of ultrasound to localise the intramesenteric accessory spleen, assess the relationship between the lesion and the symptoms of the patient, and characterise the lesion.

Wandering Spleen with Splenic Torsion: Unusual Cause of Acute Abdomen

INTRODUCTION

Wandering spleen is a rare condition characterised by laxity or lack of splenic ligaments as a result of acquired or congenital causes. There is a possibility of misdiagnosis due to its vague symptoms. In order to make a proper diagnosis, imaging techniques including abdominal ultrasonography and CT scanning are essential. Surgery is the main option of management. If the spleen is viable and there is no thrombosis in the splenic veins, splenopexy is the preferred surgical procedure. Alternatively, splenectomy plus prophylactic antibiotic and vaccination usage may be employed if spleen has infarction.

CASE PRESENTATION

A 12-year-old male child who had previously experienced constipation, mucoid diarrhoea, and abdominal distention arrived with crampy abdominal pain that had lasted for four days. The patient was tachycardic with abdominal tenderness. Whirlpool sign and lack of a spleen in its normal position were visualized on an abdominal ultrasound. The spleen was located intraoperatively in the lower abdomen, adhered to the ileum and appendix. It was 720° twisted and had necrotic areas. The patient underwent an appendectomy with splenectomy with a smooth post-operative course; combination meningococcal and pneumococcal vaccines were administered; and antibiotic prophylaxis was started for the patient.

CONCLUSION

High clinical suspicion and the use of imaging modalities like ultrasound and CT scan are extremely crucial to diagnose wandering spleen and perform splenic salvage surgery because its clinical diagnosis is challenging.
