    Chest Imaging
     

    Chest radiograph, PA-view shows increased lung volume and a fine reticular pattern bilaterally, especially in the lower zones.

     
    Area of Interest: unknown; Imaging Technique: Chest Imaging;

    High resolution CT scan of the lungs demonstrates multiple cystic airspaces with well-defined, thin walls. Some cysts are rounded, others are confluent.

    Lymphangiography

    Lymphangiography (abdominal radiograph performed 24 hours after lipiodol injection) visualizes disorganized and dilated lymphatic channels with fluid level in cyst-like lymphatic spaces.

    Retroperitoneal CT scan

    Contrast enhanced CT scan of the abdomen shows a lobulated, slightly inhomogeneous retroperitoneal mass near the inferior vena cava, aorta, psoas muscle and left kidney. An Intraperitoneal fluid collection around...

    SE T2-weighted image

    Axial SE T2-weighted MR image of the abdomen demonstrates a hyperintense mass, due to the fluid containing cyst-like lymphatic spaces and the intraperitoneal chylous effusion.

Contrast enhanced CT scan of the abdomen shows a lobulated, slightly inhomogeneous retroperitoneal mass near the inferior vena cava, aorta, psoas muscle and left kidney. An Intraperitoneal fluid collection around the mass is seen. The small rim of intraperitoneal fluid around the mass suggests rupture of the retroperitoneal lymph collections with leakage into the peritoneal cavity, causing the severe abdominal pain. The pain subsided gradually within the next 48 hours.
