“…Patients are usually asymptomatic but may present with varied symptoms depending on the location of the ectopic splenic tissue [2,3]. The most frequent locations are the peritoneum, the omentum and the mesentery, but other locations such as the pericardium, subcutaneous tissue and even brain tissue have also been described [1,4] . The implanted tissue is able to re-establish circulation and grow.…”

“…The time interval between trauma and the appearance of abdominal splenosis varies from 5 months to 32 years, with an average of 10 years, which reflects its slow growth [2,3] . The diagnosis can be a challenge because splenosis can mimic several diseases, including neoplasm [3][4][5] . Thus, a detailed clinical history, personal history (namely abdominal trauma), objective examination and adequate imaging exams are essential in order to obtain a correct diagnosis, thus preventing the patient from being subjected to more invasive procedures (such as biopsy or laparotomy) that are unnecessary and associated with high morbidity.…”

Splenosis is a benign condition which results from the self-implantation of splenic tissue on intra or extraperitoneal surfaces, after splenic trauma or splenectomy. Patients are usually asymptomatic but may present with varied symptoms related to the implantation site. The diagnosis is a challenge because abdominal splenosis can mimic several diseases, including neoplasm. The gold standard examination for its diagnosis is scintigraphy with 99mTc-labelled heat-denatured erythrocyte. When splenosis is found in an asymptomatic patient, surgical removal is not indicated. A 57-year-old male patient presented with sporadic epigastric pain and a suspected mass in the recto-sigmoid transition. Abdominal ultrasound, CT and MRI identified this mass, its characteristics and location, but failed to distinguish its nature. However, given the patient’s past history of splenectomy and because the mass showed a similar sign to that of the splenic parenchyma, a hypothesis of abdominal splenosis was raised, which was confirmed by scintigraphy with 99mTc-labelled heat-denatured erythrocyte. In this case, the diagnosis was obtained before the patient was subjected to more invasive procedures, which are associated with high morbidity, and, as in most cases, no targeted intervention was necessary.

“…The masses are usually incorrectly diagnosed as pathological masses, frequently endometriosis, and the diagnosis is rarely made preoperatively. Although splenosis is thought to be more common in men due to a higher incidence of abdominal trauma, pelvic splenosis has rarely been reported in male patients, possibly because pelvic imaging is performed less frequently than in females. Nuclear medicine scintigraphy with technetium‐99 labeled heat damaged red blood cells has previously been recommended as the diagnostic investigation of choice if the diagnosis is considered preoperatively .…”

An unusual pelvic mass: Contrast‐enhanced sonographic diagnosis of pelvic splenosis

Splenosis is an unusual condition representing auto-transplantation of splenic tissue following splenic trauma or surgery. When detected on imaging studies, the splenosis deposits are usually misinterpreted as pathological masses. We present a case where a pelvic mass incidentally visualized on an MRI examination, was proven to represent a deposit of splenosis by contrast enhanced ultrasound (CEUS). CEUS demonstrated persistent late-phase enhancement characteristic of splenic tissue. Ultrasound practitioners should be aware of this condition when an unusual abdominal or pelvic mass is encountered in a patient with a history of splenic trauma or surgery. CEUS is ideally suited to confirming the diagnosis. K E Y W O R D S CEUS, contrast enhanced ultrasound, pelvis, splenosis

“…There have been a number of other cases reported of splenosis mimicking neoplasms, although to our knowledge never as a gastric mass. Riberio et al report the case of a man with a history of splenectomy found to have a retrovesical mass thought to be an ectopic testicle 10. A laparotomy revealed multiple foci of pelvic splenosis.…”

A case of ventral hernia mesh migration with splenosis mimicking a gastric mass

This case reports the presentation and investigation of a 64-year-old woman presenting with symptoms of bowel obstruction and found to have synchronous intraluminal migration of a polypropylene mesh from a ventral hernia repair and splenosis compressing the stomach wall. The use of synthetic mesh in any type of hernia repair has a number of risks, one of which is transmigration. This is a very rare complication but has been reported in a number of cases following both open and transabdominal pre-peritoneal repairs of inguinal hernias. Heterotopic splenic tissue or "splenosis" can be a cause of a soft tissue mass, which can mimic a neoplasm leading to misdiagnosis. These implants result from either splenic trauma or after splenic surgery.
