Vertebral metastases from intracranial meningioma.

Meningioma rarely gives rise to metastases outside the brain and meninges. We report here a case of a patient who was treated for anaplastic brain meningioma with surgery and fractionated radiation therapy without any recurrence until 5 years after the operation, when she developed vertebral metastases.

[Pineal metastasis of breast cancer: case report and review]. / Métastase pinéale d'un carcinome mammaire: à propos d'un cas et revue de la littérature.

Pineal metastases of solid tumors are rare. Primary cancer is generally absent at the diagnosis, for which a cerebral MRI is important. We report a case of pineal metastasis occurring in a 76-year-old woman treated for breast carcinoma in our department.

[Intraorbital dermoid cyst. Case report and review of the literature]. / Kyste dermoïde intraorbitaire. À propos d'une observation et revue de la littérature.

Periorbital dermoid cysts are benign tumors most often seen in young children. Intraorbital location, though rare, should not be overlooked. Good quality imaging plays a major role in the etiological diagnosis, providing a precise analysis of the location of the lesion, its components, and its effects on adjacent and nearby structures, as well as in planning the surgical approach. The authors report a case of a 46-year-old male with an intraorbital dermoid cyst presenting with progressive left proptosis. Appearance on imaging (CT and MRI) was consistent with intraorbital dermoid cyst. The tumor was extirpated. Histopathologic examination confirmed the diagnosis of dermoid cyst. We also present a review of the literature.

[Nasofrontal fistula and epidermoid cyst: a case study]. / Fistule et kyste épidermoïde naso-frontaux: à propos d'une observation.

Nasofrontal fistulas, also called nasofrontal dermal sinuses, are very rare and found for the most part in children. This congenital malformation may be revealed by local infection or neuromeningitis, making this a serious disorder. We report one case of nasofrontal dermal sinus diagnosed in an 11-month-old girl, which was complicated by left fronto-orbital infection. Through this case, the authors stress the role of imaging methods in confirming the diagnosis and looking for associated cysts (dermoid and epidermoid).

[MRI and pituitary adenoma]. / IRM et adénomes hypophysaires.

Pituitary is the most important gland of the organism which can be affected by many diseases, especially by adenomatous processes. Classically macroadenoma, microadenoma and picoadenoma are described, according to the size of the pituitary adenoma. The diagnosis of microadenoma was long considered a highly difficult task and that of picoadenoma was impossible by computed tomography. Recently, the high resolution of multiplanar MRI has enabled the diagnosis of microadenomas measuring less than 3 mm (picoadenoma). For macroadenoma, MRI not only contributes to diagnosis but is particularly important to assess the extension and to detect possible complications. The aim of our study is to illustrate MRI features in pituitary adenoma.

[Elastofibroma: imaging features]. / Imagerie de l'élastofibrome dorsal.

Elastofibroma dorsi is a rare benign and slow growing fibro-proliferative lesion of unknown pathogenesis. It has a characteristic location (periscapular region) and a specific imaging appearance (songraphy, CT, MRI) allowing accurate prospective diagnosis. The recognition of this benign lesion avoids unnecessary biopsy and/or surgery. We report three cases of elastofibroma dorsi illustrating the characteristic features on sonography, CT and MRI. Involvement was bilateral in two cases.

[Solitary eosinophilic granuloma of the orbit: a case report]. / Granulome éosinophile isolé de l'orbite. A propos d'un cas.

The authors report a case of eosinophilic granuloma involving the roof and the lateral wall of the left orbit in a 5-year-old boy. The clinical presentation and especially the imaging features (computed tomography and MRI) suggested a malignant tumor and the final diagnosis was obtained by fine needle aspiration biopsy with histopathologic examination. Despite its alarming radiologic appearance, there was spontaneous healing of the eosinophilic granuloma with restitution ad-integrum of the bone.

[Hydatic acute pancreatitis: a case report]. / Pancréatite aiguë d'origine hydatique: à propos d'un cas.

Acute pancreatitis caused by hydatic cyst of the liver was rarely reported. The authors report a new case of hydatic pancreatitis characterized by visualization of hydatid membranes in the biliary tract without any biliary stone or alcoholic consumption.

[Right tracheal bronchus associated with tuberculosis pneumonia. A case report]. / Bronche trachéale droite associée à une lobite segmentaire tuberculeuse. A propos d'un cas.

Right tracheal bronchus is a rare almost always asymptotic congenital malformation. We report a case of right tracheal bronchus associated with pneumonia tuberculosis of the apical segment of the upper right lobe. We describe the characteristic of this malformation and stress the role of computed tomography scan to detect these anomalies.

[Primary cardiac sarcoma: report of 3 cases and review of the literature]. / Les sarcomes primitifs du coeur: revue de la littérature, illustrée par 3 cas.

Primary cardiac sarcoma is a rare tumor with a poor prognosis. We report 3 cases with a review of literature about this disease. There were 2 males and 1 woman. The main symptoms were thoracic pain. The clinical features were various and the thoracic ultra sonography exam allowed the diagnosis in the 3 cases. All patients had surgical remove of their cardiac tumor followed by chemotherapy. All of them died within 13 to 36 months after the diagnosis. Primary cardiac sarcoma has a poor prognosis with a mean survival less than 12 months.

[Primary lymphoma of bone: imaging features]. / Lymphomes osseux primitifs: apport de l'imagerie médicale.

Primary lymphoma of bone (PLB) has benefited from recent advances in medical imaging and immunohistochemical study that are of prognostic and therapeutic value. From 3 case reports of PLB involving the iliac bone and the skull base, we review the definition of PLB and their main features. The importance of complete initial workup for staging in order to exclude secondary bone lymphomas, more frequent and of worse prognosis, is emphasized. Diagnosis of PLB involving the skull base is more difficult to obtain and nearly always requires neurosurgical biopsy unlike PLB of peripheral bones that are more readily amenable to percutaneous biopsy.

[Breast cancer prognosis in Tunisian women: analysis of a hospital series of 729 patients]. / Pronostic du cancer du sein chez les femmes tunisiennes: analyse d'une série hospitalière de 729 patientes.

The objective of this study was to identify the anatomical-clinical aspects and determine the prognostic factors for breast cancer in the central region of Tunisia. This retrospective study involved 729 patients suffering from breast cancer, proven either by histology or cytology, diagnosed and treated between January 1990 and June 1998 at the F. Hached University Hospital in Sousse, Tunisia. The patients' average age was 50 years (ranging from 22-91). The average size of the cancer at the time of diagnosis was 49.1 mm; 90% were invasive duct carcinoma with high histo-prognostic SBR grade (level II-III: 86%). The overall survival rate was 50.5% after five years, and 50% after seven years. Using univariate analysis, significant predictive value was found with the following factors: tumor size, the clinical ganglionic level, metastases at diagnosis, the number of nodes invaded, nodal capsular rupture and lymphatic embolism, SBR grade and the delay in seeking consultation. The multivariate analysis (Cox model) isolated two prognostic factors: the initial size of the tumor (p = 0.001) and metastases at the time of diagnosis (p = 0.01). The study's results indicated that breast cancer prognosis in Tunisia remains poor primarily due to late diagnosis.

[Mucoepidermoid carcinoma appearing synchronously in the lacrimal and salivary glands]. / Carcinome muco-épidermoïde à double localisation lacrymo-salivaire.

An 86-year-old woman consulted for a swelling on the palpebral side of the upper eyelid that she had discovered 4 months earlier. Physical examination also revealed a parotid nodule on the same side. Clinical and radiological findings were in favor of a malignant lacrimal tumor. The parotid localization would correspond to either a lymph node metastasis or an intraparotid metastasis or to a primary parotid tumor with salivary metastasis; We discuss these hypotheses in light of the epidemiology, history and clinical and pathology findings.

[Post-traumatic adenoid cystic carcinoma of the lacrimal gland]. / Carcinome adénoïde kystique post-traumatique de la glande lacrymale.

A young 17-year-old man was injured on the external orbital canthus and developed a tumefaction which remained stable. After 2 years the tumefaction with exophthalmia and visual troubles. Radiological investigations suggested two diagnosis: Organized hematoma or a lacrimal gland tumor. Surgical exploration found an apparently benign tumor but histologically it was a cystic adenoid carcinoma.

[Subcapsular hematoma complicating acute pyelonephritis]. / Hématome sous-capsulaire compliquant une pyélonéphrite aiguë.

Spontaneous subcapsular renal hematoma is rare and essentially associated with malignant, or benign tumor vascular diseases, inflammatory processes. In few cases, no cause was detected. We observed one additional case in a diabetic women. She presented fever, and bilateral flank pain. Ultrasonography showed bilateral subcapsular hematoma. Computed tomography confirmed these findings and demonstrated multiple area of acute focal pyelonephritis.

[Value of imaging in the assessment of malignant fibrous histiocytoma of the soft tissues]. / Place de l'imagerie dans le bilan des histiocytomes fibreux malins des parties molles.

Malignant fibrous histiocytoma (MFH) is a rare and potentially highly malignant sarcoma. The authors report 6 cases of MFH in various sites: two in the chest wall, one in the pelvis, two in the gluteal zones and one on the scalp. Ultrasonography and computed tomography were the main imaging methods used in the assessment of the structure and extension of the tumor. A poor prognosis was noted in four cases: death within a few months in the two thoracic sites, recurrence in the pelvic and scalp lesions, radical surgery allowed recovery in two cases. A review of the literature showed that MRI and CT are complementary in the initial staging and follow-up of these patients.
