Splenosis is the autotransplantation of splenic tissue that usually follows traumatic rupture of the spleen. Generally, the splenic implants are numerous and are located within the peritoneal cavity; however, extra-abdominal splenosis does occur. The implants are rarely clinically significant and are incidental findings at autopsy or at abdominal operation, unrelated to and distant from the splenic trauma and splenectomy. Splenic implants retain their ability to function, and recurrence of a hematologic disease for which the spleen was previously removed should alter the clinician to the possibility of splenosis. The differential diagnosis includes accessory spleens, endometriosis, hemangiomas and metastatic cancer. We report three cases, two of which represent unusual complications of splenosis: a twisted pedicle of a splenic implant, which apparently caused abdominal pain, and recurrent Felty's syndrome associated with splenosis and an accessory spleen.

Splenosis is the heterotopic autotransplantation of splenic tissue that usually follows traumatic splenectomy. The clinical significance of these splenic implants and the need for surgical removal is debatable. A case of a 35 year old woman, with post-traumatic splenectomy presenting with low abdominal pain and pelvic mass is reported. Laparoscopic removal of the pelvic splenic implants dispelled all complaints.

Splenosis, the autotransplantation of splenic tissue, has been designed to preserve organ functions after splenectomy. We present the first case of laparoscopic resection of a pancreatic splenosis, in a patient who had undergone a splenectomy 31 years before, complaining of abdominal pain and diarrhea. Abdominal computed tomography (CT) scan showed an enhancing hypervascular 3-cm solid mass in the body of the pancreas, mimicking a pancreatic cancer or a neuroendocrine tumor. A diagnostic laparoscopy was planned, and a 3-cm peripancreatic nodule with a long pedicle was visualized, with many nodules close to the tail of the pancreas and in the greater omentum. They were all resected, and the specimens obtained were immediately sent for frozen-section examination, which confirmed the diagnosis of heterotopic splenic tissue. Splenosis should be included in the differential diagnosis of the pancreatic masses in patients with previous splenic surgery. A hypervascular mass on CT scan should be regarded as an adenocarcinoma of the pancreas until proven otherwise. The possibility of a neuroendocrine tumor mandates an octreotide scan and gastrointestinal hormones dosage. In the unlikely event that all tests may produce equivocal results, a diagnostic laparoscopy is mandatory, in order to obtain an accurate histopathologic diagnosis.

Splenosis is the heterotopic autotransplantation of splenic tissue usually following traumatic rupture of the spleen or surgical manipulation of splenic tissue. Although it is generally asymptomatic, it may present with abdominal pain or mass. Furthermore, there may be recurrence of the hematological disorders for which the patient underwent splenectomy. We report a rare case of splenosis in a 9-year-old girl after laparoscopic splenectomy for hereditary spherocytosis, which required laparotomy due to bowel obstruction.

Splenosis is defined as the heterotopic autotransplantation of splenic tissue because of a ruptured spleen due to trauma or surgery. It is a benign and incidental finding, although imaging tests may sometimes orient toward malignancy simulating renal tumors, abdominal lymphomas, endometriosis, among other. We report the case of a 42-year old male in whom a MRI was performed after a study due to abdominal pain. Multiple enlarged lymph nodes were observed in the abdomen, suggestive of lymphoproliferative disease. As an important background, splenectomy was carried out due to abdominal trauma at age 9. After several studies, it was decided to perform a (99m)Tc-labeled heat-damaged red blood cell scintigraphy that showed multiple pathological deposits distributed throughout the abdomen, and even the pelvis, being consistent with splenosis.

A 52-year-old man presented with abdominal pain with a background of splenectomy 25 years previously. Initial investigations lead to suspicion of a neuroendocrine tumour. Positron emission tomography octreotide scanning and chromogranin were raised. He subsequently underwent a lateral segmentectomy. The histopathology was consistent with splenosis. 1. Splenosis must be considered as differential in any patient with abdominal symptoms post-traumatic splenectomy. 2. Positron emission tomography (PET) octreotide scanning can detect splenosis giving false positives for a neuroendocrine tumour. This is the first case to describe such an association.

Splenosis is a common benign finding that occurs after splenic trauma or after splenectomy. It is auto-transplantation of splenic tissue and can be seen intra-abdominally, intra-thoracically and even subcutaneously. Splenosis is usually found incidentally at laparoscopy, laparotomy or on radiological examination and is mostly asymptomatic. Treatment is only required if a patient complains of abdominal pain, obstruction or bleeding. On radiological examination splenosis can mimic a metastatic malignant disease. For this reason it is important to recognise splenosis and know the patient's medical history concerning splenic trauma or splenectomy, thus avoiding diagnostic laparoscopy or ultrasound guided biopsy. This paper presents two patients with splenosis. Additionally, we describe how to diagnose this entity by scintigraphy with (99m) Technetium-labelled heat-denatured erythrocytes.

Splenosis represents a benign condition due to an ectopic localization of splenic tissue caused by pathologic or traumatic spleen rupture. Generally, it is asymptomatic and incidentally diagnosed during imaging performed for other reasons. Occult gastrointestinal bleeding due to an extraperitoneal localization is a rare occurrence. Differential diagnosis may be very hard and includes benign and malignant neoplasms.We describe the case of a 68-year-old Caucasian man that was admitted for an increasing lower gastrointestinal bleeding associated to a vague abdominal pain.He was assessed by means of laboratory tests, as well as by endoscopic and radiological examinations, and successfully treated with an exclusive medical approach.The patient was discharged on the ninth day and currently he is doing well.This case shows that wait and see could prove a feasible attitude for the management of clinically stable patients.

We present a rare case of pelvic splenosis, and its imaging findings, in a 54-year-old female complaining of pelvic pain and vaginal bleeding for several months. Splenosis is a benign acquired condition defined as heterotopic auto-transplantation of splenic tissue to other compartments of the body and occurs after rupture of the spleen, either traumatic or iatrogenic. Symptoms are unspecific and vary according to the location of the implants; commonly the presenting symptom is abdominal pain or enlarging abdominal mass. Owing to its intrinsic properties and safety, magnetic resonance imaging is a valuable imaging modality, in which the splenosis implants may be securely identified, showing the same signal characteristics and enhancing patterns of the normal spleen, especially visualization of serpiginous enhancement on the arterial phase is virtually diagnostic.

We present a case of splenosis of the abdomen and pelvis complicated by torsion of a splenic implant in a young female patient clinically mimicking an acute bowel ischemia. Splenosis is a benign condition defined as heterotopic auto-transplantation of splenic tissue throughout different body areas. It may occur after rupture of the spleen, either traumatic or secondary to surgical procedures. Although the presence of heterotopic splenic tissue is often asymptomatic and an incidental finding, it may present with sudden abdominal pain and bleeding. CT and MRI play a critical role in the detection of splenosis-related complications, such as torsion of the vascular pedicle and infarction. Splenosis torsion is extremely rare and it is still a diagnostic dilemma; the complication of abdominal splenosis should be considered in the differential diagnosis in patients with previous splenectomy.
