Congenital arteriovenous malformations of the genitourinary tract are rare. We report the first case of an arteriovenous malformation of the ureter. The patient presented with recurrent hematuria and left flank pain. Evaluation included an intravenous urogram, cystoscopy, and retrograde pyelography. A pedunculated lesion thought to be a fibroepithelial polyp was seen at the time of ureteroscopy, and the lesion treated by excisional biopsy and fulguration. Pathologic examination demonstrated an arteriovenous malformation. After thirty-month follow-up, the patient remains asymptomatic and free of recurrence.

Two cases of cirsoid intrarenal arteriovenous malformation, in a female aged 67 and in a male aged 18, are reported and 74 cases of the same disease collected from the Japanese literature are reviewed. Several classifications have been proposed for the so-called congenital renal arteriovenous fistula. A truly congenital form of the lesion, however, is considered to be cirsoid type and we collected only this type of arteriovenous malformation. The number of reported cases has been increasing annually. The age distribution ranged from 10 to 84 years old (mean: 38.1 years old); 49 were female and 19 male. Gross hematuria, bladder tamponade and flank pain, which can be called the triad of cirsoid intrarenal arteriovenous malformation accounted for 84.0% of the clinical symptoms, whereas cardiovascular signs and symptoms accounted for only 7.8%. The right kidney was most frequently diseased and the intrarenal lesions showed about the same distribution in the upper pole, in the middle region and in the lower pole. Pathogenetic and pathophysiologic aspects of the renal arteriovenous malformation were discussed. Renal angiography is the most helpful method for obtaining a definite diagnosis, while such findings on the intravenous pyelogram as the so-called cobble stone deformity are thought to be characteristics of the X-ray. For the treatment of cirsoid arteriovenous malformations, conservative therapies including administration of styptics were carried out in 13%, selective transcatheter embolization in 17% and surgical procedures in 70%. The recent number of transcatheter embolization has been increased to establish it as one of the distinct therapeutic methods for this disease. Among the operative methods, partial nephrectomy is now being used more than nephrectomy and 4 cases of ex vivo surgery have been reported recently in Japan.

Two cases of arteriovenous malformation of the kidney were reported. The first case was a 19-year-old female, complaining of right flank pain and gross hematuria. Right selective renal arteriography revealed a 2 x 1.5 cm large cisoid type arteriovenous malformation at the most distal region of the lower branch of the renal artery. Transcatheter embolization, using Gelfoam and absolute ethanol, was successfully done, which was confirmed with repeated digital subtraction angiography with carbon dioxide (CO2-DSA). The second patient was a 55-year-old female with past history of right idiopathic renal bleeding, complaining of right flank colicky pain and gross hematuria. Right selective renal arteriography was done without any pathological findings, while CO2-DSA documented an arteriovenous malformation in the hilar region. Transcatheter embolization was not done, because the malformation seemed to be proximally located. Thus CO2-DSA was thought to be a reliable method in the diagnosis of arteriovenous fistula.

Congenital arteriovenous malformation (AVM) of the kidney is a rare condition. Rupture of an AVM in the kidney may cause hematuria, flank pain, and urinary retention due to clots. We report 2 cases of congenital renal AVM. Both were treated with transcatheter renal arterial embolization. The signs and symptoms disappeared after embolization. On follow-up, renal function testing with a DMSA scan revealed only focal loss of renal cortical function. The clinical courses of 2 cases are reported and the literature is reviewed.

A case of subcapsular hematoma, a rare complication of acute pyelonephritis (APN) is described. A 60-year-old diabetic woman was admitted with a 3 day history of fever and left flank pain due to acute pyelonephritis. On the third day in hospital, left flank pain worsened despite use of antibiotics available for the treatments of APN and hemoglobin rapidly decreased from 11.1 to 7.9 g/dL. Ultrasonography and abdominal CT showed left subcapsular hematoma. Renal angiography demonstrated an ovoid avascular zone between the capsular artery and parenchyme of the left kidney with no evidence of tumors or vascular abnormalities, such as arteriovenous malformation or fistula. Subsequent percutaneous drainage of this subcapsular hematoma was performed and showed old blood-colored drainage. Hereby, the possibility of subcapsular renal hematoma in the course of acute pyelonephritis is stressed as a rare complication.

The authors report the case of a 6-year-old boy with a spinal cord arteriovenous malformation (AVM) who presented with acute flank pain and a delayed onset of paraplegia. An early diagnosis of a spinal cord AVM was made difficult by the absence of neurological findings on initial evaluation. Included is a description of his clinical course, and the presentation of spinal AVMs to the emergency physician is discussed.

We describe a renal arteriovenous malformation in a patient with a 1-month history of flank pain. Imaging studies were interpreted as being consistent with renal-cell carcinoma. However, Doppler ultrasonography demonstrated turbulent blood flow, and selective renal angiography confirmed the diagnosis of an arteriovenous malformation. Embolization relieved the pain. This case calls attention to the need to consider arteriovenous malformations in the differential diagnosis of central homogenously enhancing renal lesions.

We describe herein a case of complete spontaneous disappearance of a congenital arteriovenous malformation (AVM). A 28-year-old male was hospitalized for right flank pain and gross hematuria, followed by bladder tamponade. To improve the patient's symptoms, bladder irrigation was performed. Cystoscopy demonstrated bloody urine from the right ureteral orifice. Right selective renal arteriography demonstrated tortuous, coiled vascular channels with early filling of the renal vein. Thus, right renal AVM was diagnosed. However, the patient refused further treatment and was discharged. One year later, massive hematuria recurred with bladder tamponade and the patient was rehospitalized. Renal arteriography did not show any evidence of AVM and there has been no hematuria since.

This case report describes a 46-year-old man whose first symptom was an attack of acute flank pain, followed by the gradual onset neurological symptoms. We demonstrated a small nidus and serpentine signal-void area in the spinal cord by MRI and diagnosed a glomus type of spinal arteriovenous malformation (AVM). Flank pain is a rare initial finding in an adult with spinal AVM. In cases with acute flank pain, neurologists should consider spinal AVM as a differential diagnosis.

A young lady presented with complaints of right flank pain and a palpable mass. On contrast-enhanced tomography (CECT), a renal mass with extension into the inferior vena cava (IVC) - suggestive of renal cell carcinoma - was diagnosed and she underwent radical nephrectomy with en bloc excision of the IVC thrombus. Histopathology revealed a benign arteriovenous malformation that had extended into the IVC. Arteriovenous malformation should therefore be kept in the list of differentials for a renal mass with IVC extension.
