Combined juvenile polyposis syndrome and hereditary hemorrhagic telangiectasia (JPS/HHT) with MRI and endoscopic...

Area of Science:

• Genetics
• Radiology
• Gastroenterology

Background:

• Juvenile polyposis syndrome (JPS) and hereditary hemorrhagic telangiectasia (HHT) are distinct genetic disorders.
• A subset of patients with JPS and HHT share SMAD4 gene mutations, suggesting a potential overlap.
• Understanding this overlap is crucial for comprehensive patient management.

Observation:

• This case report presents a patient with the rare co-occurrence of JPS and HHT.
• The study focuses on the magnetic resonance imaging (MRI) findings in this patient.
• The MRI was performed to assess the disease burden.

Findings:

• This is the first reported case in radiologic literature detailing MRI findings in a patient with coexisting JPS and HHT.
• The MRI findings provide insights into the manifestation of this combined genetic condition.
• Detailed radiologic characteristics are presented for this rare dual diagnosis.

Implications:

• This work highlights the importance of considering combined JPS and HHT in clinical practice.
• Radiologic findings can aid in diagnosing and managing patients with this rare comorbidity.
• Further research into the SMAD4 gene's role in both conditions is warranted.
