Wandering spleen presenting as a pediatric pelvic mass

Splenic-gonadal fusion in a 6-year-old boy, confirmed by Tc-99m sulfur colloid scanning

Splenic-gonadal fusion is a rare congenital anomaly, in which splenic tissue is connected to the gonad. It is almost always on the left side, is difficult to be recognized, and unfortunately the final diagnosis is confirmed after an unnecessary orchiectomy in one-third of the cases. We report a case of splenic-gonadal fusion in a 6-year-old boy, referred for a palpable mass at the left testicle. Ultrasound and MRI were performed; and the final diagnosis was confirmed by Tc-99m colloid scanning. The child was operated, orchiectomy was avoided, the mass was removed, and pathology confirmed normal splenic tissue.

Gastric volvulus and wandering spleen

Although rare in childhood, gastric volvulus and wandering spleen share a common etiology: congenital absence of intraperitoneal visceral attachments. We report an unusual case of a patient who presented with three episodes of intractable vomiting and abdominal mass but no abdominal pain. A diagnosis could not be made until the third episode because the gastric volvulus resolved each time on placement of a nasogastric (NG) tube before any further tests could be done. During the third episode, diagnostic imaging was performed before inserting an NG tube, and the diagnosis of a mesenteroaxial gastric volvulus and an abnormally positioned spleen was made. Although both conditions are caused by abnormalities of fixation, the association of gastric volvulus and wandering spleen has been reported only once before.

The value of combined 99mTc-Sn-colloid and 99mTc-RBC scintigraphy in the evaluation of a wandering spleen

Wandering spleen is the term commonly applied to splenic hypermobility that results from laxity or maldevelopment of its suspensory ligaments. It comes to medical attention usually as an abdominal mass, or when the spleen undergoes torsion. Diagnosis on clinical grounds alone is rarely made, and ultrasonography, CT and MRI findings have no specific characteristics for this condition. 99mTc-labeled colloid taken up by the spleen may provide a specific diagnosis. We report a case of wandering spleen, in which the preoperative diagnosis was made on the basis of sequential liver-spleen scintigraphy with 99mTc-Sn-colloid and blood-pool scintigraphy with 99mTc-RBC. This is a rare case, in which hypermobility was assessed by sequential 99mTc-Sn-colloid scintigraphy, and to our knowledge, is the first case in which 99mTc-RBC scintigraphy provided useful information on splenic blood volume and its location.

Wandering spleen with torsion: appearance on CT and ultrasound

Wandering spleen is a rare entity which may present with symptoms suggestive of other, more common abdominal processes. Torsion of the long pedicle may occur causing abdominal pain. This article describes a case of wandering spleen diagnosed by computed tomography (CT). Liver spleen scintigraphy and sonography supported this diagnosis and suggested torsion. To our knowledge this is only the second case of this entity in which color flow and duplex Doppler findings have been reported.

Management of the wandering spleen

A case of torsion of a wandering spleen in an 8 year old girl is reported. The authors discuss the aetiology and management of this rare condition and review the literature. Wandering spleen is relatively more common in children than in adults. Under the age of 10 the sex distribution is even; over 10, females outnumber males by seven to one. In 66 children under 10 years, 50% of wandering spleens were lost through acute ischaemia. The authors recommend that early splenopexy replace conservative management.

Pediatric wandering spleen: case report and review of literature

Wandering spleen is a rare diagnosis, especially in the pediatric population. We reviewed the English literature from 1900 through April 1991 for all cases of wandering spleen in patients from birth through age 10. There are 50 case reports prior to the one presented here. The goals of this article are to summarize the histories, findings, and treatment of the 51 patients, describe diagnostic and treatment modalities, and increase the clinician's suspicion for wandering spleen. This condition is probably underdiagnosed and potentially treatable by splenopexy if suspected and diagnosed early in the course of disease.
