[Tumoral calcinosis: a case report]. / La calcinose tumorale: à propos d'un cas.

Tumoral calcinosis is a rare benign disease, defined by the presence of calcified deposits in periarticular tissues. The pathogenesis is unclear. We report a new case of tumoral calcinosis in a young girl, involving the left hip and both elbows. The clinical exam found a voluminous mass of soft tissues and the radiological exam showed the presence of voluminous periarticular calcifications with no bone involvement. The diagnosis was confirmed by the anatomopathological exam. The treatment remains essentially surgical and the prognosis is very good.

[Imaging features of CNS tuberculosis]. / Les aspects en imagerie de la tuberculose du système nerveux central.

CNS tuberculosis remains relatively frequent in endemic regions. Both CT and MRI are valuable for diagnosis. Even though non-specific, MRI including diffusion-weighted imaging and proton spectroscopy is more sensitive than CT for detection of some lesions. The purpose of this paper is to illustrate the imaging features of CNS tuberculosis.

[Kahler's disease presenting with a solitary cranial vault plasmacytoma]. / Maladie de Kahler révélée par un plasmocytome solitaire de la voûte.

INTRODUCTION: Solitary plasmocytoma is rarely located in the cranial vault. Usually observed, in elderly patients, occurrence during adolescence is extremely rare. We report the case of a 16-year-old patient presenting a cranial vault solitary plasmocytoma which revealed Kahler disease. CASE REPORT: A 16-year-old patient consulted for a frontal tumefaction becoming painful with diplopia. The cranio-encephalic radiography and the MRI showed a tumoral process involving cranial vault; biopsy revealed a solitary plasmocytoma. Search for multiple myeloma was negative. Six months later, a disease of Kahler was declared. CONCLUSION: Clinical and biological follow-up of cranial plasmocytoma is necessary, because progression to multiple myeloma is possible as in our observation. Imaging and particularly MRI are needed to specify the axial seat of the tumoral process and its relationship with the nervous and vascular structures.

[Thumb acrometastasis revealing lung adenocarcinoma: a case report with review of literature]. / Acrométastase du pouce révélant un adénocarcinome pulmonaire: a propos d'un cas avec revue de la littérature.

Bone metastases in the hand and foot bone (acrometastases) are rarely observed. The authors report a case of a 57-years-old man diagnosed as hand tumour, revealing a bronchic adenocarcinoma. Radiography showed destruction of the phalanx, and histology study confirmed a metastasis of the lung cancer.

[Candida arthritis of the TM joint complicating chronic otitis media]. / Arthrite candidosique de l'articulation temporo-mandibulaire compliquant une otite moyenne chronique.

Infectious arthritis of the temporomandibular joint is very uncommon, and arthritis of the TM joint as a result of candida albicans infection has not previously been reported. The authors describe a patient treated for chronic otitis media complicated by arthritis of the temporomandibular joint. The diagnosis was made using CT scan and bacteriologic sampling.

[Pseudotumoral form of sclerochoroidal tuberculosis: a case report]. / Forme pseudotumorale de la tuberculose choroïdo-sclérale: à propos d'un cas.

The Authors report the US, CT and MR features of sclerochoroidal tuberculosis simulating a choroidal tumor in a 16 Year old female presenting with acute unilateral visual loss. Fundoscopic examination and fluorescein angiography showed a tumor at the posterior pole of the globe. CT and MRI showed the choroidal process and cerebral lesions suggestive of tuberculomas. The evolution was favorable with antituberculous treatment. Ocular tuberculosis is rare, especially the pseudotumoral form. It can simulate a choroidal tumor. Radiologists should be familiar with this appearance because the lesion is reversible with antituberculous treatment.

[Cervical hydatid disease with retropharyngeal involvement: a case report]. / Hydatidose vertébro-médullaire cervicale étendue au rétropharynx: à propos d'une observation.

Hydatid disease involves the bones in 0.5 to 2% of cases, with 44% of these cases at the level of the spine. The cervical spine is a rare location, with a risk of spinal cord compression and recurrences. The Authors report a case of a young male admitted for progressive quadriplegia secondary to cervical spine hydatidosis, extending towards the retropharynx that was evaluated by CT and MRI.

[Intracranial textiloma]. / Textilome intracrânien.

The authors report a case of intracranial textiloma in a 36-year-old male diagnosed 3 years after surgery for a left spheno-orbital meningioma.

[MRI appearance of lumbar epidural abscesses: report of three cases]. / Abcès épiduraux lombaires: aspects en IRM.

The authors report three cases of non-tuberculous epidural abscess. Presenting symptoms included lumbar back pain, muscle spasms, soft tIssue swelling, and neurological deficits in all three cases. MR imaging was helpful for diagnosis and showed involvement of perivertebral soft tissues and an epidural abscess of variable size. There was no significant involvement of intervertebral disks or vertebrae. Diagnosis was confirmed by bacteriologic exam. Clinical outcome was favourable with antibiotic treatment.

[Emergency ultrasound diagnosis of ovarian torsion in children : nine case reports]. / Diagnostic échographique en urgence d'une torsion de l'ovarie chez l'enfant: à propos de neuf observations.

OBJECTIVE: To report the ultrasonographic aspects of ovarian torsion in nine pediatric cases. PATIENTS AND METHODS: The age range was from 16 months to 14 years. The patients presented with a variety of symptoms, including pain in the site of torsion. Ultrasonography was performed in all patients, and color Doppler studies in four. RESULTS: Ultrasonography showed a cystic mass in six patients, a solid mass with peripheral cysts in two patients and an adnexal cyst in one patient. Color Doppler revealed absence of flow in three patients. The patients were treated by coeliosurgery. CONCLUSION: Ovarian torsion is a serious gynecologic emergency. Torsion is rare during childhood and has a non-specific clinical presentation. Ultrasound and Doppler are the imaging study of choice. The ovarian salvage was attributable to the combination of delay in patient presentation and surgical delay.

[A rare cause of spinal cord compression: osteochondroma of the thoracic spine. A case report]. / Une étiologie rare de la compression médullaire: l'exostose thoracique intracanalaire. A propos d'un cas.

Osteochondroma or exostosis is the most common benign tumor of bone, but vertebral involvement is rare. The authors report the case of a 16 years old male with a family history of hereditary multiple exostoses who presented with spinal cord compression. MR examination showed an intraspinal extradural bone lesion at the T1-T2 level, hyperintense on T1 weighted and hypointense on T2 weighted images, causing marked cord deformity. The CT scan showed a tumor of the body and left pedicle of T2 with severe narrowing of the spinal canal.

[Tuberculosis of the posterior vertebral arch. A case report]. / Tuberculose de l'arc vertébral postérieur. A propos d'un cas.

Tuberculosis of the spine usually involves the vertebral body and intervertebral disk. Involvement of the posterior arch is rare. We report a case of tuberculosis involving the posterior elements of the T4 and T5 vertebrae in a 38 year old woman. CT is helpful to assess bony structures whereas MRI is ideal to evaluate the neural structures. Clinical, radiographic, and therapeutic considerations regarding tuberculosis of the spine are reviewed.
