Renal Pelvis Carcinoma with Renal Vein or Inferior Vena Cava Involvement Linked to Early-onset Lung Metastasis Based on CT Scan Diagnosis

Abstract

Tumor involvement of the renal vein or IVC is linked to early-onset lung metastasis in renal pelvis cancer based on CT scan diagnosis.

Invasion of Adjacent Lumbar Vertebral Body from Renal Pelvis Carcinoma: Associated With Bone Metastasis But Easily Overlooked on Initial CT Scan

“…Bone metastasis occurs either via direct invasion of bone tissue or secondarily to bone marrow, with the latter being most common (2). Renal pelvis carcinoma involving the renal vein or inferior vena cava (IVC) has been linked to early-onset lung metastasis, as noted in our previous study (3). Direct invasion of renal pelvis carcinoma to L1 and L2 vertebral bodies may play a role in the pathogenesis of bone metastasis development.…”

“…Diagnosis of L1 and L2 vertebral body invasion and bone metastasis is possible based on symptoms, CT scan, and radionuclide images (8). The development of radicular pain, which is characterized by pain radiating along the dermatome of a nerve (9), as well as back pain, is related to invasion L1 and L2 vertebral bodies, which cause nerve root compression or irritation (3). CT scans are useful for the staging and detection of L1 and L2 vertebral body invasion and osteolytic bone metastasis (4,10).…”
