Thoracic splenosis: History is the key

Area of Science:

• Medical Case Reports
• Radiology
• Surgical Pathology

Background:

• Splenosis is acquired ectopic splenic tissue following splenic rupture or splenectomy.
• Diagnosis can be challenging due to potential mimicry of malignancy.
• Abdominopelvic splenosis is common, but thoracic splenosis is rare.

Observation:

• A rare case of thoracic splenosis with multiple intraparenchymal nodules is presented.
• The patient presented decades after initial splenic trauma.
• Thoracic splenosis typically involves the pleura, with intraparenchymal lesions being less common.

Findings:

• Detailed patient history is crucial for diagnosis.
• Nuclear imaging studies are valuable for confirming splenosis.
• This case demonstrates a rare intraparenchymal presentation of thoracic splenosis.

Implications:

• Accurate diagnosis of splenosis avoids unnecessary invasive procedures like biopsies.
• Early and correct diagnosis prevents potential complications associated with misdiagnosis.
• Recognition of rare presentations like intraparenchymal thoracic splenosis improves clinical management.
