Intravenous leiomyomatosis is also refered as [IVL]. Intravenous leiomyomatosis is characterized by the extension into venous channels of histologically benign smooth muscle tumor arising from either the wall of a vessel or from a [[uterine leiomyoma]]. The etiology of intravenous leiomyomatosis is unclear. Intravenous leiomyomatosis must be differentiated from other diseases such as [[renal malignancies]] and [[sarcoma]]. The median age is 45 years, with patients ranging from 26 to 70 years old. Only females may develop intravenous leiomyomatosis. Surgery is the mainstay of therapy for intravenous leiomyomatosis. It can grow in to lymphatics /veins.

Findings on an [[ultrasound]] imaging [[diagnostic]] of intravenous Leiomyomatosis include a vascularized [[thrombi]] within the [[pelvic]] [[Vein|veins]] and [[Inferior vena  cava]]. Findings on [[MRI]] [[diagnostic]] of intravenous leiomyomatosis include a leiomyomatous [[lesion]] or a distorted [[uterus]] with projections into [[vasculature]].

Overview

Intravenous leiomyomatosis is also refered as IVL. Intravenous leiomyomatosis is characterized by the extension into venous channels of histologically benign smooth muscle tumor arising from either the wall of a vessel or from a uterine leiomyoma. The etiology of intravenous leiomyomatosis is unclear. Intravenous leiomyomatosis must be differentiated from other diseases such as renal malignancies and sarcomas. The median age is 45 years, with patients age ranging from 26 to 70 years old. Only females may develop intravenous leiomyomatosis. Findings on CT scan diagnostic of intravenous leiomyomatosis include an irregular mass exhibiting heterogeneous enhancement with extension into adjacent veins. Findings on an ultrasound imaging diagnostic of intravenous Leiomyomatosis include a vascularized thrombi within the pelvic veins and Inferior vena cava. Findings on MRI diagnostic of intravenous leiomyomatosis include a leiomyomatous lesion or a distorted uterus with projections into vasculature. Surgery is the mainstay of therapy for intravenous leiomyomatosis. It can grow into lymphatics /veins.

Historical Perspective

Classification

  • There is no established system for the classification of intravenous leiomyomatosis.

Pathophysiology

Causes

  • The etiology of intravenous leiomyomatosis is unclear.[7]

Differentiating Intravenous Leiomyomatosis from other Diseases

Epidemiology and Demographics

  • There is no available data on the exact incidence of intravenous leiomyomatosis.
  • The median age at the time of diagnosis of IVL is 45 years, with patients age ranging from 26 to 70 years old. [9]
  • Female are exclusively affected with intravenous leiomyomatosis.[10]
  • Intravenous leiomyomatosis is seen more commonly in white females.[11]

Risk Factors

Screening

  • There is insufficient evidence to recommend routine screening for intravenous leiomyomatosis.

Natural History, Complications and Prognosis

Diagnosis

Diagnostic Criteria

History and Symptoms

Physical Examination

Laboratory Findings

  • There are no specific laboratory findings associated with intravenous Leiomyomatosis.

Electrocardiogram

  • There are no ECG findings associated with intravenous Leiomyomatosis.

X-ray

  • There are no x-ray findings associated with intravenous Leiomyomatosis.

Echocardiography or Ultrasound

CT scan

MRI

Other Imaging Findings

  • There are no other imaging findings associated with intravenous leiomyomatosis.

Other Diagnostic Studies

  • There are no other diagnostic studies associated with intravenous leiomyomatosis.

Treatment

Medical Therapy

  • There is no treatment for intravenous leiomyomatosis.

Surgery

  • Surgery is the treatment of choice, and complete removal of the tumor is mandatory.
  • Recurrences may occur up to 15 years after the primary occurrence in patients with Incomplete resection of the tumor.[24]
  • Bilateral oophorectomy causes shutdown of hormonal stimulation hence helps preventing recurrence.[25]
  • Surgical removal can be done in single or staged procedures.[26]
