[Intratympanic meningioma. Apropos of a case].

A 40 year old woman presented with a meningioma of the intratympanic region, a very rare localization which raises problems of differential diagnosis from jugular glomus tumors. A brief historical survey and complete etiopathogenic study are presented, and clinical features and results of complementary examinations, particularly angiography and computed tomography, are described. Treatment is exclusively surgical and diagnosis is confirmed with certitude by histopathology only.

[Changes in bone marrow cellularity close to cancer metastases. Cyto-histologic study].

Before starting any therapy, we systematically studied by biopsy the bone marrow of 66 patients suffering from various cancers and suspect of marrow metastasis. Metastatic cells were thus found in 45 patients. Bone marrow composition was examined on histologic sections by granulometric method, while relative proportions and morphology of the various hematopoietic series were examined on cytologic prints. It then appeared that any important metastatic invasion goes together with deep alterations of the surrounding hematopoietic tissue, with frequent peri-metastatic collagenic fibrosis and hypoplasia of the various cell-lines; when metastatic growth is still moderate, hematopoietic tissue is, on the contrary, often hyperplastic, "irritative". These marrow alterations are not to be found far from the metastasis, and thus seem to be directly linked to the actual presence of cancerous cells.

[Rheumatic spondylodiscitis in spondylarthropathies].

The involvement of enthesis like disc space is the typical lesion of spondylarthropathies. Out of 240 patients with spondylarthropathies, 10 (7 M, 3 W; mean age: 37 years) have spondylodiscitis, affecting a total of 13 disc spaces: 1 cervical, 2 thoracic, 10 lumbar. The mean duration of spondylarthropathy at the time of diagnosis of spondylodiscitis is 10 years. Spondylodiscitis has a variable clinical presentation: painful (6 cases), asymptomatic (4 cases). Its coexistence with typical radiographic signs of spondylarthropathy added to the exclusion of bacterial origin, permit to link it to spondylarthropathy. Its evolution is generally favourable.
