Massive splenic pseudochist in pregnancy. A rare condition

Area of Science:

• Obstetrics and Gynecology
• Surgical Pathology
• Abdominal Imaging

Background:

• Splenic cystic lesions are uncommon, categorized into epithelial (Type 1) and non-epithelial (Type 2, pseudocysts).
• Splenic pseudocysts typically arise secondary to trauma, infarction, or infection.
• No prior cases of splenic pseudocysts in pregnant patients have been documented in Mexico.

Observation:

• A 26-year-old pregnant woman presented asymptomatically with a large (25 × 18 × 10 cm) intraparenchymal splenic cystic lesion.
• The patient underwent an open splenectomy during the second trimester of pregnancy.
• Post-operative recovery was satisfactory.

Findings:

• Histological examination confirmed the splenic lesion as a pseudocyst.
• This represents the first documented instance of a splenic pseudocyst in a pregnant individual in Mexico.

Implications:

• This case expands the understanding of rare splenic pathologies during pregnancy.
• Highlights the importance of considering splenic lesions in pregnant patients, even if asymptomatic.
• Suggests splenectomy is a viable option for managing large splenic pseudocysts during pregnancy.
