Follicular lymphoma in a patient with splenosis: a case report

Refractory Immune Thrombocytopenic Purpura with Abdominal Splenosis: A Complex Case

Immune thrombocytopenia (ITP) is an acquired thrombocytopenia resulting from immune-mediated platelet destruction via antiplatelet antibodies and T cells. Medical management of ITP includes corticosteroids and multiple other adjunct therapies, with splenectomy generally being reserved for severe, refractory cases. In this clinical case report, we describe the evaluation of a 35-year-old male with a history of prior traumatic splenic injury who presented to the emergency department endorsing easy bruising and a petechial rash, ultimately found to have severe thrombocytopenia. The patient was diagnosed with primary ITP that proved to be refractory to a number of first- and second-line medical therapies. His course was complicated by the presence of abdominal splenosis discovered at the time of planned splenectomy and intra-abdominal hemorrhage requiring splenic artery embolization thereafter. To our knowledge, this is one of few published cases of ITP complicated by abdominal splenosis, highlighting the need to consider splenosis and the presence of accessory splenic tissue in cases of refractory ITP.

Abdominal and pelvic splenosis: atypical findings, pitfalls, and mimics

Splenosis is an acquired form of ectopic splenic tissue that typically arises after trauma or splenectomy. It is often an incidental image finding in an otherwise asymptomatic patient, but the spectrum of symptoms varies based on the site of implantation. Radiologists should be familiar with the imaging features of splenosis to avoid mistaking it for malignancy. Splenosis has identical imaging features to that of the native spleen on US, CT, MRI, and nuclear medicine examinations. Therefore, when the radiologic findings support the diagnosis of splenosis, the patient can be spared invasive procedures for tissue sampling.
