Avascular necrosis of the epiphysis of the first metatarsal bone.

We report a case of avascular necrosis of the epiphysis of the right first metatarsal in a 6-year-old boy. Radiographs showed sclerosis, collapse and a crescent sign in the epiphysis. The diagnosis was confirmed by magnetic resonance imaging and scintigraphy. Arch support was the therapy of choice. Six months after the onset of symptoms, a definite reossification was present. To our knowledge, this is the first radiological report of avascular necrosis of the epiphysis of the first metatarsal bone in the world literature, which prompted a review of the osteochondroses and their etiology.

Ectopic localisation of adrenal cortex.

We present a case of concurrence of ectopic adrenal cortex with a renal cell carcinoma. The diagnosis of the accessory adrenal tissue was made by CT-guided biopsy. With this case report, we draw attention to a specific differential diagnostic problem, policy and to the MR characteristics of ectopic adrenal cortex.

The use of preoperative fistulography in patients with a second branchial cleft anomaly.

The preoperative fistulography used in cases of second branchial cleft anomalies is an effective method of showing the exact anatomy and topography of these fistulas in the neck. This visualisation is very important because the only therapeutic solution is complete surgical resection. This method is easy to perform and is painless. We report two patients with branchiogenic anomalies. The diagnosis was established by fistulography and histological examination.

Strecker stent placement in the superior mesenteric artery for recurrent ischemic colitis.

We report on a case of recurrent superior mesenteric artery (SMA) stenosis with symptomatic mesenteric angina after SMA angioplasty. Stent placement of postostial atherosclerotic disease was proposed, with successful result. Moderate aortic protrusion was noted. Feasibility of PTA and stenting of mesenteric stenoses become increasingly obvious, but long term follow-up studies still have to provide sufficient results on clinical outcome and possible complications.

Aortic coarctation associated with an aberrant right subclavian artery.

We report a case of aortic coarctation associated with an aberrant right subclavian artery in a young male who was investigated for hypertension. Angiography, CT examination with multiplanar reconstruction and MRI were useful in delineating the extension of the coarctation and the exact anatomy of the aberrant right subclavian artery.

Systemic to pulmonary artery shunting.

Two cases showing systemic to pulmonary artery shunting, during the venous phase of bronchial arteriography are presented. In the first patient with chronic bronchiectasis, the shunting is believed to be due to newly formed vessels in the granulomatous tissue. At pulmonary angiography, the increased pressure in the pulmonary arteries simulated an angiographic defect due to dilution of the contrast by retrograde opacification from a left to right shunt. In a second patient with proven pulmonary embolism a true defect was present at pulmonary angiography. Systemic to pulmonary artery shunting is believed to develop secondary to hypoxia.

Intracavernosal injection of prostaglandin E1 as an alternative for papaverine in penile angiography.

Arteriography of the penile vasculature was performed after intracavernous injection of prostaglandin E1 in five patients. Penile tumescence was obtained in three patients with a dose of 10 micrograms and in the other two patients with a dose of 20 micrograms. Mean duration of penile tumescence was 1 h 36 min. Visualization of the penile vasculature was adequate in all patients. Local pain was a minor side effect in one patient. These preliminary results suggest that prostaglandin E1 might represent an alternative for papaverine in the angiographic study of male impotence.

Unilateral congenital nasolacrimal mucocele.

A case of a congenital nasolacrimal mucocele is reported. This very uncommon finding presents usually with a diagnostic triad on CT: an intranasal cystic mass, a dilated nasolacrimal duct and lacrimal sac.

Percutaneous transluminal laserangioplasty with balloon centered direct argon laser light. Experience with 12 patients and a minimal follow-up of 6 months.

Laser angioplasty with direct argon laser light, combined with a special centering balloon (Lastac system) was performed in 12 patients with a single superficial femoral artery occlusion. The mean length of the occlusion was 5.4 +/- 2.15 cm with a mean duration of occlusion of 7.8 +/- 5.9 months. Initial angiographic success was obtained in 9/12 procedures. Reason of failure was perforation in 1 patient and impossibility to pass the stenosis due to calcifications in 2 patients. Early rethrombosis in 1 patient reduced the primary success rate to 8/12 procedures. Peripheral emboli occurred in 2 patients, both successfully treated by thrombolysis or surgery. Of the 8 recanalized arteries, all remained patent with a mean follow-up of 7.1 +/- 0.68 months. It remains to be determined on larger series whether the Lastac system offers substantial advantages over other, less expensive systems of laser angioplasty.

Embolization of iatrogenic renal hemorrhage following percutaneous nephrostomy.

Renal bleeding of iatrogenic origin was diagnosed in three patients with massive hematuria. Although percutaneous nephrostomy was the initial injury in all cases, the angiographic presentation was very variable. All cases were successfully managed with arterial embolization, using different techniques. Symptoms regressed totally in all patients avoiding surgical intervention.
