Hypercalcaemic encephalopathy as a presenting manifestation of sarcoidosis

A 66-year-old woman presented to us with features of encephalopathy with asterixis, preceded by unsteadiness of gait and behavioural abnormalities. On subsequent investigations, hypercalcaemic crisis and compromised renal function were noted. Stepwise approach to determine the cause behind hypercalcaemia with compromised renal function revealed underlying granulomatous disease (sarcoidosis). Later, development of maculopapular rash and subsequent biopsy from the lesion confirmed the diagnosis of sarcoidosis. Her clinical and biochemical parameters improved considerably on initiation of conservative pharmacological therapy.

Severe hypercalcaemia of primary hyperparathyroidism: Could giant adenoma be the real culprit rather than carcinoma?

Introduction Hypercalcaemic crisis is a rare manifestation of hyperparathyroidism and occurs in 1.6–6% of patients with primary hyperparathyroidism (pHPT). Although such high serum calcium levels (>14mg/dl) are attributed to malignancy, it is also associated with benign disease of the parathyroid glands. The aim of this study was to evaluate the clinical features and treatment modalities of patients with severe hypercalcaemia who underwent surgery for pHPT. Methods The medical records of 537 patients who underwent parathyroidectomy in our department for pHPT between 2005 and 2019 were reviewed retrospectively. Twenty-four (4.4%) of the patients were described as having severe hypercalcaemia. Results Among 24 patients, 71% were female and the mean age was 55.7 years (range: 40–71 years). The mean serum calcium level at time of diagnosis was 15.9mg/dl (range: 14–22.7mg/dl). According to postoperative pathology reports, solitary adenoma, parathyroid cancer and parathyromatosis were diagnosed with the rates of 87.5%, 8.3% and 4.1% respectively. The mean weight of the solitary parathyroid lesions was 14.9g (standard deviation: 8.9g, range: 4–38g). The mean longest diameter was 2.87cm (standard deviation: 1.4cm, range: 1–5.5cm). Serum calcium levels were within the normal range on the first postoperative day in 75% of the cases. Conclusions Severe hypercalcaemia is a rare but urgent condition of pHPT and requires prompt management. Accelerated surgery after adequate medical treatment should be performed. It is important to emphasise that giant adenoma, which is a benign disease, may be a more common cause of severe hypercalcaemia than carcinoma, unlike previously thought.

Hypercalcaemic Crisis Due to Primary Hyperparathyroidism: Report of Two Cases

Introduction A hypercalcaemic crisis, also called para thyrotoxicosis, hyper parathyroid crisis or parathyroid storm, is a complication of primary hyperparathyroidism (PHPT) and an endocrinology emergency that can have dramatic or even fatal consequences if it is not recognised and treated in time. Case presentation Two cases presented in the emergency department with critical hypercalcaemic symptoms and severe elevation of serum calcium and parathyroid hormone levels, consistent with a hypercalcaemic crisis. The first case, a 16-year-old female patient, had imaging data that highlighted a single right inferior parathyroid adenoma and a targeted surgical approach was used. The second case, a 35-year-old man was admitted for abdominal pain, poor appetite, nausea and vomiting. Laboratory tests revealed severe hypercalcaemia, hypophosphatemia and an increased serum iPth level. There was no correlation between scintigraphy and ultrasonography, and a bilateral exploration of the neck was preferred, resulting in the exposure of two parathyroid adenomas. The patients were referred for surgery and recovery in both cases was uneventful Conclusion These cases support the evidence that surgery remains the best approach for patients with a hypercalcaemic crisis of hyperparathyroidism origin, ensuring the rapid improvement of both the symptomatology and biochemical alterations of this critical disease.
