Cryoglobulinemic neuropathy: a pathological study.

A 53-year-old woman developed symmetrical polyneuropathy of the lower limbs a few months after she was found to have myeloma with cryoglobulinemia. In musculocutaneous nerve biopsy material, electron microscopy showed both axonal degeneration and demyelination. The most striking finding was the presence, in the endoneurial space, of numerous masses of closely packed tubular structures. These masses also were found in the walls of all the vasa nervorum and within the lumen of some vessels. The morphological features and dimensions of the deposits within nerve were identical to those of cryoprecipitates extracted from serum and examined with the electron microscope. An example of myeloma neuropathy with cryoglobulin deposits within the endoneurial space has not been reported previously.

[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.
