[Pulmonary edema secondary to the intravenous administration of iodized contrast. A clinical case with high-resolution tomodensitometry studies].

Contrast media related reactions are numerous and of variable gravity. We report a case of pulmonary edema related to the intravenous administration of contrast media. Cardiogenic and non cardiogenic pulmonary edema are pathophysiologic possibilities. High resolution CT findings associate patchy ground glass areas and smooth thickening of subpleural septa, both rapidly disappearing.

[Lipoma of the filum terminale: a prospective tomodensitometry study].

A lipomatous aspect of the filum terminale is sometimes recognized in routine lumbosacral CT studies as a small (1 to 2 mm) tubular fatty hypodensity that lies posteriorly in the dural sac. To study the epidemiologic frequency and pathological significance, the authors prospectively reviewed the standard lumbosacral CT studies of a large series of 1033 adult patients suffering from mechanical problems. The lipomatous aspect was encountered in 39 of them (3.77%). The average size was about 1 mm and never exceeded 2 mm (92%) except for 3 cases. The commonest site was L4-L5 but the anomaly was more commonly seen at two levels. Despite the lack of histological proof, the authors consider the lesion benign and trite with two restrictions: the pediatric cases (not studied in their series) and the patients presenting a lipoma greater than 3 mm; for these two groups further investigations are recommended to exclude a tethered cord syndrome.

[A cause of intestinal intussusception in an adult].

Inflammatory fibroid polyp is a very rare tumor involving the gastrointestinal tract and especially the stomach and small bowel. It presents either as a solitary pedunculated or sessile lesion arising from the submucosa. Despite its large size and sometimes very infiltrating growth, the polyp is benign and has a good prognosis. The aetiology remains unknown but it probably represents a reactive proliferation similar in many respects to the granuloma pyogenicum. We report an ileal case which presented itself as an acute intussusception. The very typical and complete sonographic and tomodensitometric findings of this intussusception are detailed. The polyp alone does not have noteworthy radiological characteristic signs and must be included in the large and essentially histological differential diagnostic of gastrointestinal tumors.

[Infected urachal cyst].

There is a wide variety of pathologies associated with the presence of urachal remnants. We describe a case of infected urachal cyst in a young adult male, with classical symptoms of dysuria, lower abdominal pain, and fever. Ultrasound, cystography and CT are described, ultrasound being often the modality of choice. Differential diagnosis of acute abdominal and pelvic pain or a midline lower abdominal mass at this age should include infection of an urachal remnant.

[Lumbar arachnoid cysts: 2 unusual cases].

Two cases of arachnoid cyst in the lumbar region are described. One is intradural, acquired, and associated to severe arachnoiditis while the other is extradural in location and probably congenital. The interest of myelography, CT myelography, and MRI for the diagnosis is discussed.

[Anorectal anaplastic cancer (neuroendocrine)].

An extensive case of undifferentiated neuroendocrine carcinoma with small cells of the anorectal region is reported. The carcinoma is related to pulmonary anaplasia and quite rare in the colonic and rectal region. Its aggressivity is considerable with a strong propensity for hematogenous and lymphatic metastases and with a disastrous prognosis: 0% survival over 1 year. The incidence, the characteristic features, the histogenesis, and the anatomical pathology of this rare neoplasm are mentioned. Furthermore, the case illustrates a radiological pattern typical for major lymphatic dissemination with an intra- and extraparietal component. The mechanism of dissemination is explained by the "lymphatic block" theory. The absolute necessity of obtaining an histology in radiologically unusual and/or extensive cases is mentioned.

[The value of ultrasonography and computerized tomography in mandibular diseases: apropos of 2 cases of chronic fistulizing mandibular osteitis].

Though US and CT are infrequently used for the detection of mandibular disease, both techniques definitely contributed to the detection and extension work-up of fistulizing chronic mandible osteitis in our 2 patients. US clearly visualizes the mandible margin and enables detection of abnormal foramina. CT is highly valuable for the visualization of the complex (flat and curved) structure of the mandibular body and the adjacent soft tissues. While routine intraoral radiography remains necessary and sufficient in easy pathological conditions, it appears from our experience that CT and US are of unique value in detecting complex or complicated mandibular disease, in particular when involving the surrounding soft tissues.

[Pelvic plexiform neurofibroma: typical aspects in CT].

Plexiform neurofibroma is a relatively uncommon but characteristic manifestation of neurofibromatosis. Two pelvic cases were found by CT in two young patients in whom it was the first fortuitous manifestation of the disease. The CT pattern, which seems to be in close relation with pathology, is described and illustrated. This pattern is so typical that there is no difficulty to establish the differential diagnosis. The question of sarcomatous transformation is more problematic by CT.

[Endobronchial lipoma: a potential CT diagnosis].

Bronchial lipomas are rare and benign neoplasms. Computed tomography can provide a powerful adjunct to conventional modalities in determining the nature of an endobronchial lesion. The reflex vasoconstriction can also be nicely depicted.

Gastric ulcer penetrating the anterior abdominal wall: ultrasound diagnosis.

We report two rare cases of penetration of the anterior abdominal wall by gastric peptic ulcers. The full diagnosis was made by ultrasound, which showed similar findings: sharply delineated, hyperechoic craters clearly traversing the gastric wall and covered by hypoechoic inflammatory components of the abdominal wall. Because ultrasound is increasingly used as a primary procedure for evaluation of abdominal complaints, efforts should be directed toward exploring the accessible portions of the gastric and duodenal walls to detect peptic ulcer disease and its complications.

Pseudoaneurysm of the internal carotid artery: treatment with a covered stent.

Dissection of the cervical segment of the internal carotid artery may occur spontaneously or after trauma. We report the management of a 53-year-old right-handed man with progressive dizziness and neck pain 6 weeks after a motor vehicle collision. The clinical and neurologic examinations were normal. The CT scan led to the diagnosis of a pseudoaneurysm of the right internal carotid artery near the skull base. We successfully treated this post-traumatic lesion with a covered stent. The patient underwent the endovascular procedure under general anesthesia and transcranial Doppler monitoring. No neurologic event was observed. Obliteration of the pseudoaneurysm with preservation of the carotid artery was achieved. The patient was discharged from the hospital 72 hr later with no complications. Clinical and imaging follow-up at 6 months was unremarkable.

[Pictorial essay. Infarction of the greater omentum: can US and CT findings help to avoid surgery?].

Infarction with or without torsion of the greater omentum is an uncommon but well recognised acute abdominal condition which was seldom diagnosed preoperatively before the widespread clinical use of US and CT. The aetiology is unknown and speculative. In most cases the pathology is right sided and clinical presentation consists of an acute or subacute flank pain with mild peritonism usually evoking appendicitis or cholecystitis. Recently, US and CT have proved to provide sufficiently typical, consistent and well-recognizable features to avoid unnecessary surgery. We report on six typical -five right sided and one left sided- cases investigated with CT and US. Two patients underwent surgical treatment, one because the usually spontaneous regression of the entity was ignored and the other because of extremely severe clinical symptoms. In the other four patients, conservative medical management was preferred and successful. Even though US may be efficient if performed by a well-trained echographist, CT appears to be the procedure of choice as it is operator independent and reliable for excluding mimicking surgical conditions or associated pathology.
