Abstract

Background: Meningioma is a rare association of Multiple endocrine neoplasia type 1 (MEN 1) and very few cases has been reported in literature. Clinical Case: a 75-year-old woman showed severe headache, disturbed consciousness and convulsions. A diagnosis of cerebral meningioma was made and surgical excision was done, histopathological examination confirmed meningioma; patient was transferred to the ICU postoperatively for monitoring. Patient’s consciousness was not regained in full and remained in delirium, follow up investigations revealed: serum calcium of 13.2 mg/dl (8.5 to 10.5 mg/dl), serum sodium 141 mmol/L (135-145 mmol/L) and potassium 4.9 mmol/L (3.5-5 mmol/L), serum parathormone of 850 pg/mL (10-65 pg/mL), primary hyperparathyroidism was suspected; further investigations revealed inferior parathyroid adenoma on ultrasound which elicited focal tracer uptake on sesta-mibi parathyroid scintigraphy. Patient did excision of the lesion and was confirmed by histopathological examination to be parathyroid adenoma. Patient recovered well postoperatively, consciousness was regained and no neurological defects ware present. Genetic studies where performed and was found positive for MEN type 1 gene. Whole body Ga-DOTATATE PET/CT was then done to exclude any associated tumors and no tracer uptake was found. Patient was discharged, family members were offered genetic analysis and were counselled on the importance of screening. Conclusion: MEN type 1 can rarely present with meningiomas with symptoms very similar and easily confused with hypercalcemia and the diagnosis can be missed.
