An unusual presentation of lipofibromatous hamartoma in an infant. A case report

Area of Science:

• Medical Imaging
• Pediatric Oncology
• Pathology

Background:

• Lipofibromatous hamartomas (LFH) are rare, benign tumors typically affecting adults.
• These tumors characteristically occur in the third and fourth decades of life.
• LFH commonly present in the upper extremity.

Purpose of the Study:

• To report an atypical case of lipofibromatous hamartoma.
• To highlight the diagnostic challenges in pediatric LFH.
• To describe the magnetic resonance (MR) imaging findings in an infant with LFH.

Main Methods:

• Case report of a one-month-old female infant.
• Detailed clinical and radiological evaluation.
• Magnetic resonance (MR) imaging analysis of the lesion.

Main Results:

• The lipofibromatous hamartoma presented in an unusually young patient (one month old).
• The lesion's MR imaging characteristics mimicked those of a vascular malformation.
• This presentation underscores the variability in LFH appearance.

Conclusions:

• Lipofibromatous hamartomas can occur in infants, deviating from typical demographics.
• MR imaging findings can be misleading, requiring careful consideration of differential diagnoses.
• Early recognition and accurate diagnosis are crucial for appropriate management of pediatric LFH.
