Brain abscess caused by the fungus Cladosporium trichoides is rare. Only 20 cases of brain abscess caused by this fungus are reported in the literature. We report a case of brain abscess caused by Cladosporium trichoides in a healthy adult male. The relevant literature on this subject is reviewed.

Short-course chemotherapy is well established for the treatment of pulmonary tuberculosis but not for extrapulmonary disease. We present a series of 35 cases in which chemotherapy for tuberculous meningitis was given for a period of less than 2 years. Short-term therapy was associated with recrudescence of tuberculous meningitis and, in some cases, with the development of deep cerebral infarcts and permanent neurological deficits. We think short-term chemotherapy for tuberculosis of the central nervous system is inadequate.

Two patients with galactorrhea-amenorrhea and bilateral visual field defects were studied. Routine radiologic examination of each patient revealed a normal sella turcica and no demineralization of the posterior clinoid process. Serum prolactin levels were elevated (patient V. G., 80 ng/ml; patient S. R., 204 ng/ml). Within 2 months of bromocriptine therapy, the serum prolactin levels were normal (patient V. G., 12.21 ng/ml; patient S. R., 8.25 ng/ml) and the bilateral visual field defects were corrected. Bromocriptine has been shown to control prolactin secretion in patients with prolactin-secreting pituitary tumors. Normalization of restricted visual fields following bromocriptine therapy indicates the possibility of an anatomical regression of pituitary hyperplasia or an underlying prolactin-producing microadenoma. It is speculated that the modality of functional galactorrhea reflects hyperplasia of the lactotrophs preceding a nodular and ultimately an adenomatous change. The continuous and prolonged administration of bromocriptine may prevent such a progressive sequence. Further experience is required to validate this possibility.
A 24-year-old man with left sixth through twelfth cranial nerve palsies and severe, fluctuating, systemic arterial hypertension was found to have a large, vascular, catecholamine-forming glomus jugulare chemodectoma. After his electrolyte imbalance was corrected, left external carotid embolization (using Gelfoam) was carried out. The systemic blood pressure stabilized at around 160/100 mm Hg over the next 12 hours. Ten hours later the hitherto conscious patient developed acute arterial hypotension, lapsed into coma, and died. Autopsy showed tumor infarction, swelling, cerebellar tonsillar herniation, and medullary compression. An unusual complication of glomus tumor embolization is highlighted. The roles of preliminary decompressive surgery and urgent resuscitation by vasopressors are discussed.
