Hypercalcaemia associated with disseminated cryptococcosis

Abstract

We report an elderly man who presented with giddiness and right-sided weakness, constipation and constitutional symptoms for 6 months duration. Blood investigations indicated hypercalcaemia with normal serum phosphate and acute kidney injury. Serum intact parathyroid hormone was suppressed. CT revealed bilateral tiny lung nodules with right upper lobe tree in bud appearance and incidental findings of bilateral adrenal lesion. Tuberculosis was ruled out. CT adrenal showed multiseptated hypodense rim enhancement adrenal lesion bilaterally. Adrenal function tests were normal except for low dehydroepiandrosterone (DHEA). Right-sided cervical lymph node biopsy confirmed fungal infection with the presence of intracellular and extracellular fungal yeast. Serum cryptococcus antigen titre was positive. Our final diagnosis was disseminated cryptococcosis with lungs, bilateral adrenal gland and lymph nodes involvement. The patient was then treated with antifungal treatment. Serum calcium was normalised after 1 month with marked clinical improvement.

Keywords: adrenal disorders; calcium and bone; cryptococcosis; cryptococcus.

CT adrenal protocol showed multiseptated hypodense rim enhancing adrenal lesions bilaterally. The right adrenal lesion measured 2.7 cm × 2.4 cm × 3.1 cm, with attenuation of 30 HU (plain phase) and total wash out rate of 90%. The left adrenal measured 2.0 cm × 2.4 cm × 2.6 cm, with attenuation of 22 HU (plain phase) and total wash out rate of 100%.
