[Developmental adrenal tuberculosis. Value of x-ray computed tomography].

Two cases of Addison's disease secondary to active adrenal tuberculosis are reported. Computed tomography showed hypertrophy of the adrenal gland, which was bilateral in one case and unilateral in the other. Repeat computed tomography scans during antituberculous chemotherapy demonstrated a progressive change of the adrenals toward atrophy and calcification, while the adrenal function remained impaired. The authors recall that adrenal tuberculosis may be unilateral first, then bilateral, and that the gland is initially hypertrophic before hormonal deficiency appears; later on, adrenal atrophy and calcification develop. Computed tomography seems to be useful in the aetiological diagnosis of Addison's disease. Moreover, it helps in determining whether or not antituberculous therapy is indicated, which is not always easy to decide in the absence of "active" focus. The finding, with or without positive tuberculin skin tests, of an adrenal hypertrophy unexplainable by any other pathology (e.g. metastasis, histoplasmosis) should call for antituberculous treatment, especially since it sometimes results in recovery of adrenal function.

[Functional renal failure (FRF) in cirrhosis (author's transl)].

Frequent complication of advanced cirrhosis, spontaneous or in response to different causes, FRF is chiefly characterized by hyponatraemia, progressive azotaemia, hyperkalaemia and severe oliguria. Its functional nature is proved but its mechanism remains doubtful: it may be due to decreased "effective" plasma volume or renal arteriolar constriction. Its treatment is disappointing and in spite of new technics, gives only transitory improvements.

[The value of ultrasound-guided cyto-biopsy in the study of livers with abnormal ultrasonograms].

This retrospective study considers the diagnostic reliability of 97 cyto-biopsies performed with a fine needle and guided by ultrasonography in 92 patients with one or several suspicious liver lesions. The results of the cyto-biopsy were compared with the final diagnosis obtained by histological examination or by the evolution. In 65 confirmed malignant tumors, fine needle biopsy was concordant in 54 cases. The sensitivity of this method in the diagnosis of malignant liver lesions was 83% with a specificity of 93%. In 54 malignant cytologies, the differentiation between primary or secondary lesions was possible in 31 cases (57%). In 32 confirmed benign lesions, fine needle biopsy was concordant in 30 cases. This study confirms the advantage of cyto-biopsy guided by ultrasonography in the positive and etiological diagnosis of malignant liver tumors.
