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.

"Wandering Spleen" With Lymphomatous Involvement.

ABSTRACT: Wandering spleen is a rare condition caused by either lack or the laxity of ligaments, which results malposition in the lower abdomen or pelvis. FDG PET/CT is the cornerstone of the staging procedures in the management of lymphomas leading to upstaging and picking up occult lesions in the spleen and extranodal sites. Herein, we reported initial staging 18 F-FDG PET/CT findings of a woman with Hodgkin lymphoma whose spleen was absent in normal position and multiple intense heterogenous hypermetabolism in a pelvic mass raised a suspicion of wandering splenic involvement. The confirmation was made with selective spleen SPECT/CT images thereafter.

Wandering liver, spleen, and kidney: what the radiologist needs to know.

The wandering spleen, wandering liver, and wandering kidney are rare diagnoses that can be asymptomatic or are associated with nonspecific symptoms, making the clinical diagnosis elusive. In addition, given the small number of cases, these conditions are not well understood. Major complications of wandering spleen result from torsion of the vascular pedicle with resultant ischemia, physiologic dysfunction, and/or infarction. Wandering liver is commonly associated with bowel obstruction, particularly colonic volvulus, with very rare reports of hepatic ischemia or infarct. Wandering kidneys are not commonly associated with serious complications. In many cases, the wandering spleen, liver or kidney can be found in their anatomic position on static imaging and are only diagnosed during ultrasound or with serial radiographic or cross-sectional imaging with different patient positioning, or with prior studies demonstrating different locations of the involved organ. Treatment approaches for uncomplicated wandering spleen, liver, or kidney include watchful waiting and splenopexy, hepatopexy, or nephropexy, respectively. Complicated wandering spleens are treated with splenectomy. Given the variable clinical presentation of these conditions, imaging plays a pivotal role in diagnosing these rare and often incidentally discovered phenomena.

Gastric outlet obstruction secondary to a wandering spleen: systematic review and surgical management of a case.

INTRODUCTION: A wandering spleen occurs when laxity or absence of the suspensory ligaments allows migration throughout the abdomen. Gastric outlet obstruction resulting from this abnormality is rare. We present a systematic literature search and a case that was managed successfully with surgical intervention at our centre. METHODS: A systematic search of the PubMed, Embase™, Medline® and Google Scholar™ databases was carried out employing the combined search terms "gastric outlet obstruction" AND "wandering spleen". Six results were included for final analysis. RESULTS: All six search results described a single case each. Patients underwent surgical management (open or laparoscopic) after initial investigation utilising a range of modalities. There were no mortalities reported at 90 days. The single case we present was complicated by gastric perforation; the patient made a successful recovery following open splenopexy and stapled wedge resection of the stomach. CONCLUSIONS: A wandering spleen is a rare diagnosis and there are only six reported cases of gastric outlet obstruction secondary to a wandering spleen in the literature. None report associated gastric perforation. There are a variety of presenting symptoms, intraoperative findings and operative techniques used to address the gastrosplenic abnormality. The case reported by our centre adds to this limited evidence base and demonstrates a successful outcome from definitive surgical management. We highlight the need to seek early gastro-oesophageal expertise if any gastric pathology is found together with anatomical abnormality of the spleen.

Torsión esplénica / Splenic Torsion

Introducción: El síndrome de torsión se incluye dentro de los síndromes que causan abdomen agudo quirúrgico. Como causa poco frecuente de este síndrome se encuentra la torsión esplénica en bazos que tienen anomalía en su fijación. Objetivo: Informar sobre la evolución de una paciente tratada por torsión de un bazo errante. Presentación del caso: Paciente de ocho años de edad, femenina, de color no blanco de la piel, con antecedentes de dolor abdominal crónico recurrente, que acudió al Servicio de Urgencias del Hospital Pediátrico de Cienfuegos Paquito González Cueto con dolor abdominal agudo, intermitente, de 48 horas de evolución, vómitos, abdomen doloroso a la palpación profunda en cuadrante superior izquierdo y masa palpable en flanco lateral del mismo lado de tres cm. Se sospechó una torsión esplénica. Se realizó, como complementario diagnóstico ultrasonido abdominal Doppler y tomografía contrastada de abdomen. Se hizo laparotomía y se encontró bazo torcido, con cambios de coloración por la isquemia, que recuperó su color normal después de la destorsión. Se fijó el órgano a la pared abdominal. La evolución posquirúrgica resultó satisfactoria. Conclusiones: La torsión esplénica, aunque infrecuente, debe sospecharse en pacientes con dolor intermitente y masa palpable, principalmente en flanco lateral izquierdo. La tomografía contrastada resulta el examen diagnóstico de elección y se requiere de un diagnóstico temprano para poder conservar el bazo, órgano muy importante para una mejor función inmunológica en los niños(AU)

Introduction: Torsion syndrome is included among the syndromes causing acute surgical abdomen. A rare cause of this syndrome is splenic torsion in spleens with abnormal fixation. Objective: To report on the evolution of a patient treated for torsion of an errant spleen. Case presentation: Eight-year-old female patient, non-white skin color, with a history of recurrent chronic abdominal pain, who attended the Emergency Department of the Paquito González Cueto Pediatric Hospital of Cienfuegos with intermittent acute abdominal pain of 48 hours of evolution, vomiting, painful abdomen on deep palpation in the left upper quadrant and palpable mass in the lateral flank of the same side measuring three centimeters. Splenic torsion was suspected. Doppler abdominal ultrasound and contrasted tomography of the abdomen were performed as a complementary diagnosis. Laparotomy was performed and the spleen was found to be twisted, with changes in color due to ischemia, which recovered its normal color after detorsion. The organ was fixed to the abdominal wall. The postoperative evolution was satisfactory. Conclusions: Splenic torsion, although rare, should be suspected in patients with intermittent pain and palpable mass, mainly in the left lateral flank. Contrast tomography is the diagnostic test of choice and early diagnosis is required to preserve the spleen, a very important organ for better immune function in children(AU)

Laparoscopic Splenectomy of a Wandering Pelvic Splenomegaly in a Young Woman Treated in Childhood with Surgery for Diaphragmatic Hernia and Adhesiolysis for Intestinal Obstruction.

BACKGROUND Wandering spleen (WS) is a rare medical condition in which the spleen migrates from its usual position commonly to the pelvis or lower abdomen assuming an ever-wandering state. The incidence of ectopic spleen is 0.2%, with variable clinical manifestations from asymptomatic to abdominal emergency. Symptoms are most attributed to complications related to torsion, so that a nonoperative management of a WS is not advised. According to the literature, 69.5% of patients with WS need splenectomy and 78.6% need laparotomy. CASE REPORT The patient exhibited vague intermittent lower abdominal pain for 6 months due to progressive torsion of the spleen, which resulted in venous congestion. Abdominal investigation revealed a mobile intra-abdominal mass and parenchymatous consistency in the pelvis. Diagnosis by computed tomography outlined abdominal splenomegaly with abnormal position both of pancreas and stomach. Laparoscopy established a giant spleen, with a lengthened pelvic and twisty vascular pedicle. In its ectopic location, the spleen had dragged the pancreas with it, which had taken a vertical position. The classic splenic ligaments were not recognizable. Spleen was removed with median laparotomic incision. Splenectomy was performed to prevent any traumatic fractures of the spleen, a complete twist of the splenic hilum, and the onset of recurrent acute pancreatitis. CONCLUSIONS Wandering spleen is rare in patients presenting with acute abdominal pain. An approach supported by clinical findings and investigation, even considering splenectomy over splenopexy, and laparoscopy over open surgery, may solve and prevent complications and health risks.

Wandering spleen, which is torsioned with the distal pancreas.

There are many causes of acute abdominal pain. One of them is wandering splenic torsion. We aimed to discuss a case in which the distal pancreas and spleen were torsion together and underwent splenectomy in the light of the literature. A 19-year-old male patient with sudden onset of abdominal pain underwent splenectomy after physical examination and imaging revealed splenic torsion. Early diagnosis is important as life-threatening complications may develop. Emergency surgery should be performed in patients with splenic ischemia. It should be kept in mind that the pancreas may be torsioned along with the spleen. Surgeons need to be careful during splenectomy to avoid injury to the pancreas.

Diagnosis and treatment of splenic torsion in children: preoperative thrombocytosis predicts splenic infarction.

BACKGROUND: Pediatric splenic torsion is a rare entity, and the most common cause is wandering spleen. This study aimed to summarize our clinical experience in the diagnosis and surgical treatment pediatric patients with splenic torsion, and to use preoperative thrombocytosis as a preoperative predictive factor for splenic infarction. METHODS: From January 1st, 2016 to December 31st, 2021, 6 children diagnosed as splenic torsion were included. All patients were surgically treated and followed up. The clinical data was collected including clinical presentations, laboratory tests, imaging results, surgical procedures, and prognosis. Clinical experience of diagnosis and surgical treatment were summarized. RESULTS: There were 4 females and 2 males, with median age at surgery 102.6 (range 9.4-170.7) months. Abdominal pain and abdominal mass were the most common presentations. The diagnosis of splenic torsion depended on imaging studies, and adjacent organ involvement (gastric and pancreas torsion) was observed on contrast CT in one patient. Five patients were diagnosed as torsion of wandering spleen, and one was torsion of wandering accessory spleen. Emergent laparoscopic or open splenectomy was performed in all patients. Pathology revealed total splenic infarction in 4 patients, partial infarction in 1 patient, and viable spleen with congestion and hemorrhage in 1 patient. Preoperative platelet counts were elevated in all 4 patients with splenic infarction, but normal in the rest 2 with viable spleen. Postoperative transient portal vein branch thromboembolism occurred in one patient. CONCLUSIONS: Imaging modalities are crucial for the diagnosis of pediatric splenic torsion and adjacent organ involvement. Preoperative thrombocytosis may predict splenic infarction. Spleen preserving surgery should be seriously considered over splenectomy in patients with a viable spleen.

Patients with gastric volvulus recurrence have high incidence of wandering spleen requiring laparoscopic gastropexy and splenopexy.

PURPOSE: Though gastric volvulus in neonates and infants resolves by conservative therapy and aging, some cases require surgical intervention. This study aimed to review the cases of gastric volvulus requiring surgical intervention and evaluate their characteristics. METHODS: We retrospectively reviewed gastric volvulus cases requiring surgical intervention. Surgical indication was persistent acute gastric volvulus and repeated hospitalization for gastric volvulus. We evaluated the characteristics of those cases requiring surgical intervention and the surgical results of laparoscopic gastropexy. RESULTS: The median age of patients included was 4 years (range: 1-6 years). All eight cases of gastric volvulus requiring sugery had congenital spleen diseases. Six of the eight cases suffered from a wandering spleen, while two cases presented with situs inversus with asplenia. Both splenopexy (preperitoneal distension balloon [PDB] or blunt separaion methods) and gastropexy were performed in cases with wandering spleen. No postoperative complications were reported in any of the eight cases, except the recurrence of gastric volvulus due to suture shedding in one case. CONCLUSION: Laparoscopic gastropexy for gastric volvulus and splenopexy for cases concomitant with wandering spleen were found to be effective surgical approaches. Both PDB and blunt separation methods for making extraperitoneal pockets for the spleen were employed successfully.

Multimodality imaging of developmental splenic anomalies: tips and pitfalls.

Anomalies in number and location may occur during splenic development. This review aims to offer a brief overview of splenic function and embryology and a detailed account of the imaging appearances using different imaging techniques of the normal spleen and various congenital splenic anomalies including (1) abnormal viscero-atrial situs, (2) splenogonadal fusion, (3) intrapancreatic accessory spleen, (4) wandering spleen, and (5) splenosis. Emphasis is placed on the salient features that help radiologists recognise important associations (e.g., asplenia/polysplenia in situs abnormalities), avoid diagnostic pitfalls (e.g., mistaking intrapancreatic accessory spleen as pancreatic neoplasms), and potential complications (e.g., acute torsion in wandering spleen). The correct identification of the said anomalies from more sinister causes, such as malignancies, are essential, where early intervention is necessary.
