This research aims to clarify the diagnostic challenges posed by pseudo-tumoral portal cavernous cholangiopathy (PCC) and differentiate it from malignancies.
Three cases of pseudo-tumoral PCC were reported, diagnosed through imaging techniques including CT and MRI.
Imaging revealed hallmark features such as non-visualization of the portal vein and extensive periportal collaterals.
PET-CT was utilized in one case to assess FDG uptake confirming a benign etiology.
Imaging techniques showed consistent patterns of homogeneous enhancement and absence of diffusion restriction.
Diagnosis of pseudo-tumoral PCC helped prevent unnecessary invasive procedures, particularly biopsy, due to the presence of collateral vessels.
The study emphasizes the need for increased awareness among clinicians regarding the characteristics of PCC to avoid misdiagnosis.
