“…Moreover, contrasted‐enhanced CT and MRI show heterogeneous enhancement within the mass, which is due to necrosis or hemorrhage. Extraluminal leiomyosarcoma can invade surrounding tissues and should be differentiated from retroperitoneal tumors or peripheral organ tumors . A few articles reported the sonographic features of IVC leiomyosarcoma as a predominantly solid and lobulated retroperitoneal mass, sometimes containing small cystic components .…”

“…The diagnosis of IVC leiomyosarcoma is challenging, especially in early stage, due to the absence of specific symptoms. Imaging is of great value in the diagnosis and differential diagnosis of IVC leiomyosarcoma . CT and MRI images have been reported, but ultrasonographic features are less well known, especially with contrast‐enhanced ultrasonography (CEUS).…”

Primary leiomyosarcoma of the inferior vena cava (IVC) is a rare and fatal disease.Imaging is the main diagnostic method. CT and MRI images of IVC leiomyosarcoma have been published, but ultrasonographic features have been scarcely described, especially with contrast-enhancement. We report the case of a patient in whom ultrasonography incidentally revealed a mass in the IVC. Contrast-enhanced ultrasonography showed heterogeneous enhancement in the arterial phase with some irregular non-enhanced areas, and mild clearance in the venous phase. The location and nature of the lesion as shown by ultrasonography were confirmed by CT and MRI.

“…In intraluminal type of LMS, IVC lumen is dilated and filled with mass [10]. In extra luminal type of LMS, the primary tumour of the IVC grows exophytic, which is often misdiagnosed as tumour of the adjacent organs like adrenal gland mass or sarcoma arising from retroperitoneum with direct invasion into IVC [11].…”

Leiomyosarcoma (LMS) is a malignant mesenchymal tumour, which originates from the smooth muscle cells. Leiomyosarcoma of vascular origin most commonly originates from inferior vena cava (IVC). Around 400 cases of IVC leiomyosarcoma were reported in literature till date. Here we report a case of a 58-year-old male diagnosed to have right large palpable supra renal mass. Contrast enhanced computed tomography (CECT) of abdomen and pelvis revealed a well-defined soft tissue mass measuring around 10 cms with heterogeneous post contrast enhancement at right suprarenal region with a clinical differential diagnosis of adreno cortical carcinoma and retroperitoneal leiomyosarcoma was made. Intra-operatively right adrenal gland was normal, and the mass was seen arising from the side wall of IVC at the confluence of right adrenal vein. Complete excision of mass done, followed by repair of IVC rent. Histopathological examination showed leiomyosarcoma. Adrenal gland was normal, margins were free of tumour and immunohistochemistry (IHC) was positive for caldesmon and smooth muscle actin (SMA). Patient was on follow up for the past 1 year without local recurrence or distant metastasis.

“…Nevertheless, many case reports have used MRI for IVC LMS diagnosis. 8,[12][13][14][15][16][17][18] Compared with CT, MRI can provide more accurate information about the tumour's location, extent, collateral vessels, and adjacent structures with superior soft-tissue resolution, special sequences, and safer contrast material. The T2-weighted black blood sequence and high concentration contrast agent can overcome the limitations of CT, clearly revealing the vessel walls and lumens of IVC and collateral vessels.…”

Background: Leiomyosarcoma of the inferior vena cava (IVC) is a rare malignant tumour with poor prognosis. Surgical resection is the first line of treatment to achieve the best possible outcome. However, precise preoperative evaluation is essential to guide therapeutic decisions. Here, the preoperative evaluation potential of gadobutrol-enhanced magnetic resonance imaging (MRI) was assessed in the management of a 42-year-old patient with a large IVC mass. Methods: The patient first underwent enhanced computed tomography (CT), but the relationship between the left renal vein and the mass in the dilated IVC was ambiguous, and it remained unclear whether the right hepatic vein was invaded by the lesion. To make a precise assessment of the tumour, the patient subsequently underwent high-resolution MRI angiography examination combined with high-concentration contrast medium gadobutrol. Results: MRI demonstrated the integrity of the right hepatic vein and the left renal vein. Following a multidisciplinary consultation, a complicated surgery including complete resection of the mass, artificial vessel replacement of IVC, total hepatectomy, and bilateral nephrectomy with liver and kidney auto-transplantation was performed successfully. The surgical plan formulated after reviewing the MRI preoperatively was adhered to the course of the surgery. Postoperative CT re-examination showed that the blood flow of the artificial blood vessel and the right hepatic vein was unobstructed. Histopathological examination confirmed the tumour to be a leiomyosarcoma. Conclusion: Preoperative imaging diagnosis and assessment have important implications for the surgical planning of IVC leiomyosarcoma. High-resolution MRI angiography examination with high concentration contrast medium gadobutrol may be of particular benefit in IVC tumours.
