“…Venous enlargement has been advanced as the main criterion of tumoral thrombus [20]. However, enlargement of the renal vein or the IVC is a nonspecific finding [2,21]. It was observed in 3 of 53 (6 %) of veins with bland thrombi in the present series and has been observed in previous studies [7,21].…”

Renal carcinoma: diagnosis of venous invasion with Gd-enhanced MR venography

et al. 2000

The aim of this study was to evaluate the usefulness of gadolinium-enhanced time-of-flight magnetic resonance venography (MRV) in the diagnosis of bland thrombosis/tumoral invasion in the preoperative assessment of renal cell carcinoma. Preoperative precontrast and enhanced GRE fast lowangle shot (FLASH) images of 36 patients with renal adenocarcinoma were reviewed and compared with pre- and post-contrast T1-weighted images. All patients underwent surgery, and MR findings were blindly and prospectively compared with surgical and pathologic data, considered the standard. Renal vein and vena cava were involved in 17 and 9 patients, respectively; right atrial extension was present in one patient. Precontrast spin-echo (SE) and FLASH images were 88% sensitive and 100% specific in the detection of venous involvement, respectively, and enhanced FLASH images 100% sensitive and 96% specific. The nature of thrombus (neoplastic or bland) was more accurately assessed (McNemar's, p < 0.05) with FLASH-enhanced MR images (sensitivity 89%; specificity 96%) than with SE and precontrast FLASH images (sensitivity 79%; specificity 94%). Our data suggest that use of Gd-enhanced MRV might improve preoperative assessment of vascular involvement in renal carcinoma.

“…However, extended survival through surgery has recently been reported, regardless of whether the tumor was supra-or infradiaphragmatic [4]. The key point in the management of this neoplasia is the correct assessment of the extension of the endocaval thrombus [9][10][11]. The pre operative evaluation must show the presence of possible cavai wall infiltration and extension into the hepatic veins.…”

“…Restricted diffusion may also be noted in the tumor thrombus. Infiltration of the IVC wall is considered the most specific sign for tumor embolism; however, it is less sensitive and if present, surgical resection of the involved segment of IVC is necessary [6] . CECT is also useful in providing information about the loco regional invasion of the tumor and to identify the presence of metastatic deposits in liver, bone, lungs and lymph nodes.…”

Peripheral primitive neuroectodermal tumor (PNET) of the kidney is a rare, aggressive tumor known for its recurrence and metastatic potential. Despite the frequency of venous extension to the renal veins and inferior vena cava, pulmonary tumor embolism at the initial presentation is not common. We report a case of 22-year-old female with PNET of the kidney who presented with tumor embolism in the inferior vena cava (IVC) and bilateral pulmonary artery. The patient underwent surgical resection and histopathological analysis confirmed the presence of tumor within the IVC and pulmonary arteries. The patient received adjuvant chemotherapy and is currently doing well on follow-up. Core tip: Traditionally, an aggressive renal mass with pulmonary tumor embolism is an entity well described in renal cell carcinomas. However, renal primitive neuroectodermal tumor (PNET), a rare and aggressive tumor, can have a similar presentation. The severity of the clinical manifestations of pulmonary tumor embolism is highly variable and less predictable. Bland thrombus often mimics tumor emboli in imaging and histopathology is often confirmatory. Tumoral extension into the pulmonary artery is not necessarily associated with pulmonary metastasis. Surgical removal of the thrombus along with the primary tumor followed by adjuvant chemotherapy may prolong the survival in these patients.Chinnaa S, Das CJ, Sharma S, Singh P, Seth A, Purkait S, Mathur SR.
