Presacral myelolipoma: CT findings

Area of Science:

• Radiology
• Oncology
• Pathology

Background:

• Presacral myelolipomas are rare, benign tumors originating from the bone marrow.
• They are typically located in the extraperitoneal retrorectal space.

Observation:

• This study describes the computed tomography (CT) findings of a confirmed presacral myelolipoma.
• The lesion is characterized as an encapsulated, mixed soft tissue mass with a predominant fatty component.

Findings:

• Presacral myelolipomas commonly occur in asymptomatic individuals, typically between the 5th and 8th decades of life.
• A slight female predominance is noted, and significant hematologic disturbances are usually absent.

Implications:

• Presacral myelolipoma should be considered in the differential diagnosis of fat-containing presacral lesions.
• Familiarity with the characteristic CT appearance can facilitate percutaneous needle biopsy, potentially avoiding surgical intervention.
