["Méta-analyse": a web-based tool for research and analysis of radiology papers]

Finding articles providing answers to specific clinical questions is greatly facilitated by the availability of indexed Medline abstracts using the Pubmed search engine. Nonetheless, the large number of references sometimes requires a time-consuming review of multiple abstracts. In order to streamline the search process, we have created a tool facilitating the search and review of these abstracts. We present here this tool named "Méta-analyse".

[Percutaneous retrieval of intravascular foreign bodies]

Percutaneous extraction of intravascular foreign bodies is becoming an increasingly common technique. It is an effective and low aggressive way to avoid surgery. We report four new cases of percutaneous retrieval.

[Ectopic thyroid]

PURPOSE OF STUDY

Ectopic thyroid is defined as thyroid tissue not located anterolaterally between the second and the fourth tracheal cartilage. This anomalous localization results from abnormal embryologic development and/or migration of the gland. The purpose of this study is to demonstrate the role of imaging in the preoperative evaluation of ectopic thyroid.

MATERIAL AND METHODS

A 13-year-old girl with no other significant medical history, consulted for dysphonia, fullness in the throat and breathing difficulties. Examination of the oral cavity and oropharynx showed a large mass attached to the base of the tongue, the mass was evaluated by ultrasanography, computed tomography, magnetic resonance imaging and scintigraphy.

RESULTS

Ultrasound sonography showed a well-defined hypoechogenic mass in the posterior end of the tongue. Scintigraphy showed hyperfixation at the base of the tongue with no fixation in the normal thyroid site. Computed tomography scan revealed a spontaneously hyperdense spherical basilingual mass with a high enhancement after contrast injection. In MRI, the mass was isointense with the muscle in T1-weighted images and hyperintense in T2 weighted images.

CONCLUSION

Ectopic thyroid must be evoked in the presence of any basilangual mass. Scintigraphy and ultrasanography are gold standard in demonstration the ectopic thyroid tissue. But computed tomography and MRI playing an increasingly important role in the diagnosis, in determination of the malignant transformation and planning the surgical approach.

[Isolated synovial chondromatosis of the subacromial bursa: report of a new case and review of the literature]

Synovial chondromatosis is a rare metaplasia of the synovium of unknown etiology that may involve occasionally the subacromial bursa. We report a new case diagnosed by ultrasound in a 30-year-old man and we present pathogenetic, diagnostic and therapeutic features of this disease with a literature review.

[Vertebral and spinal cord hydatidosis: contribution of imaging]

The authors report the case of a vertebromedullary hydatidosis revealed by medullar compression in a 40-year-old male patient. Magnetic resonance imaging showed lesions of the seventh and eighth dorsal vertebras, cystic lesions in the epidural space and in the perivertebral soft tissues. Surgical excision lead to clinical cure. Vertebromedullary hydatidosis is rare and severe. Modern techniques of imaging are very helpful for the diagnosis and the follow-up of patients after treatment.

[Carpal scaphoid chondroma complicated by fracture: a case report]

The carpal scaphoid is an uncommon localization for chondroma. Ten cases have been reported in the literature. We report a new case of right carpal scaphoid chondroma complicated by fracture in a 30 year-old man. The diagnosis was strongly suggested by the computed tomography scan and confirmed at pathology examination of the operative specimen. Treatment consisted in tumor enucleation and a cortico-cancellous graft to fill the gap followed by plaster case immobilization. Clinical and radiological outcome was favorable.

Le syndrome de Eagle : à propos d’un cas

Eagle's syndrome, also known as elongated styloid process, is an entity that may be the source of craniofacial and cervical pain. It is frequently reported but is probably more common than generally considered. The symptoms related to Eagle's syndrome can be confused with those attributed to a wide variety of Oropharyngeal and Maxillofacial diseases. The paucity of information in the radiologic literature prompted this report.

[A patient with a diaphragmatic mass]

Cystic teratoma of the diaphragm is a rare, generally asymptomatic, disease. We report a case which was disclosed by the development of fever and pain in the left hypochondria. Imaging ruled out surgical emergency and led to the diagnosis, describing the relations of the tumor.

[Aorticopulmonary paraganglioma. A case report]

Paraganglioma is a tumor which develops from the paraganglion system, generally in the adrenal medulla (90%). Thoracic localisations are exceptional and arise essentially for the aortic and subaortic bodies, leading, in this case, to an anterior and posterior localisation. We report a case of non-chromaffin non-secreting aorticopulmonary paraganglioma, discovered fortuitously in a 64-year-old man.

[Osteoid osteoma of the tarsal navicular bone: an uncommon localization]

We report a case of subchondral osteoid osteoma of the tarsal navicular bone. Osteoid osteomas are often located in the foot, mainly in the talus. This is the first report in the literature of a tarsal navicular bone localization. Diagnosis was difficult and established late due to misleading clinical presentation simulating mediotarsal arthritis.

[Diaphragmatic bronchogenic cyst: a rare case report]

Retroperitoneal bronchogenic cysts are rare and those located in the diaphragm are exceptional. We describe an additional case of bronchogenic cyst of the left crus of diaphragm. Diagnosis of a diaphragmatic lesion was confirmed during laparotomy and complete resection was successful. Final diagnosis was done on pathology.
