[Subcutaneous trochanteric bursitis: an unrecognized cause of peritrochanteric pain revealed by imaging]. / La bursite sous-cutanée trochantérique. Cause méconnue de douleur péritrochantérienne révélée par l'imagerie.

We present four cases of subcutanea trochanterica bursitis (one involving both sides). The bursitis was acute and inflammatory in two cases, chronic and microtraumatic in one, asymptomatic in one and septic in the last case. The acutely inflamed bursa may contain a blood effusion increasing the pain. CT and MRI provide distinctive images for the diagnosis of these particular types of periarticular diseases.

[Multiple calcified cerebral metastases revealing bronchial adenocarcinoma. Apropos of a case]. / Métastases cérébrales calcifiées multiples révélatrices d'un adénocarcinome bronchique. A propos d'un cas.

Calcified brain metastases are rare. They are unique or multiple. The primary site is lung, breast, gastro-intestinal tract, uterine cervix, bone or may be unidentified. It corresponds pathologically to an adenocarcinoma, a sarcoma or to a squamous cell carcinoma. We report a case of multiple calcified brain metastases discovered before primary tumour (bronchial adenocarcinoma), raising the problem of differential diagnosis resolved by stereotaxic brain biopsy.

[Computerized tomography-guided needle biopsy for the diagnosis of pulmonary nodules: analysis of a series of 41 patients]. / Ponction à visée diagnostique de nodules pulmonaires sous repérage scanographique: analyse d'une série de 41 patients.

This study was aimed at assessing percutaneous biopsy under computerized tomography (CT) guidance, its results in terms of diagnostic value, factors contributing to its complications or success, and its indications. Results obtained from a series of 41 patients and data from previous clinical trials were compared. Patients who were not eligible due to either poor physical condition or a tumor that could not be reached were not included into the study. Various factors, ie, the tumor location, the size of the lesion, the distance between the lesion and the thoracic wall, and the type (histological and/or cytological) of samples, were analyzed. Results were evaluated according to the disease evolution or pathological findings. Tumoral cells were found in 23 samples. Eighteen samples were negative for malignancy, with eight benign lesions and ten false negative. Complications that occurred just after the biopsy were recorded. Failures and complication factors were analyzed and compared to those already described. CT-guided needle biopsy is an admitted alternative to thoracotomy, even for small nodules deeply located. The use of this technique should be discussed when fiberoptic endoscopy leads to negative results. Various tumors cannot be reached using CT-guided needle biopsy and this technique is more efficacious for bulky nodules. The thickness of lung parenchyma passed through does not seem to change the risk of pneumothorax. The use of laser guidance might help locate the tumor with more accuracy.

[Value of echography in a case of polyorchidism]. / Intérêt de l'échographie dans un cas de polyorchidisme.

We report a case of polyorchidism diagnosed by scrotal ultrasonography and confirmed by surgery. Sixty eight cases have been reported in the literature.

[Blunt injury of the larynx by hanging. X-ray computed tomographic aspect]. / Traumatisme fermé du larynx par pendaison. Aspect scanographique à propos d'un cas.

The closed laryngeal traumas by attempt of hanging are rarely studied by medical imaging. The lesions are evaluated by fiberoptic endoscopy and CT scan. We report a case of complicated lesions of the larynx with rupture of the cricothyroid membrane, diagnosed by CT scan and we discuss the usefulness of this technique.
