mimicking peritoneal carcinomatosis: a case report.
is a frequent consequence/complication of traumatic splenic rupture because of the "transplantation" of splenic tissue through local mechanical seeding or hematogenous dissemination.

diagnosed 48 years after thoracoabdominal trauma.
Beside Paget disease, various other tumors , coeliac ganglia , splenosis
, sarcoidosis , and subacute stroke  have been reported to cause false-positive PSMA-PET imaging findings.
Also, leftsided pleural nodules with a history of prior trauma may reflect splenosis
while empyemas occasionally involve the mediastinal pleura.
Accessory spleen needs to be distinguished from splenosis
which is an acquired condition associated with splenic trauma or surgery having incidence of 67% in these patients (11).
Possible diagnoses are; endometriosis and splenosis
. The appearance is not consistent with malignant nodules.
develops when splenic tissue is seeded within the abdomen or pelvis (Figure 4) following trauma 12].
is an acquired anomaly of the spleen which occurs in case of splenic trauma or splenectomy.
Ectopic splenic tissue can manifest in two distinct forms: splenosis
and accessory spleens.
is the presence of splenic tissue at various ectopic sites, usually the peritoneum, omentum, mesen tery, or pelvis, in relation to previous trauma.
