We present an interesting case of immobilisation hypercalcaemia. Case: A 22-year-old female with no significant past medical history was admitted following a road traffic accident (RTA). She suffered severe abdominal injury, skull and multiple limb fractures and underwent left below-knee amputation, bowel resection and nephrostomy. The admission to ITU was prolonged, and seven weeks into the admission, she developed hypercalcaemia (adjusted calcium: 3.8, N: 2.2 – 2.6 mmol...

Introduction: Hypokalaemia is a common biochemical abnormality seen in inpatients; it is usually mild and iatrogenic. We report a rare case of muscle paralysis due to severe unprovoked hypokalaemia, presenting on acute medical take.Case: The patient presented with a two week history of epigastric pain, nausea, vomiting, muscle spasms and dizziness. Past medical history included asthma, vitiligo, pernicious anaemia as well as long standing history of unex...

Introduction: We present a challenging case of central diabetes insipidus secondary to hypothalamic large B cell lymphoma. These are rare tumors accounting for less than 1% of lymphomas. Conventional treatment involves the MATRIX regime (methotrexate, rituximab, thiotepa, cytarabine) chemotherapy, coupled with intensive intravenous fluid therapy to avoid methotrexate toxicity. The main challenges in the management of this case were maintaining fluid and electrolyte balance in ...

Parathyroid cysts (PCs) are rare lesions usually found during exploration of neck and mediastinal masses. Ten percent of PCs can be functional and release parathyroid hormones causing hypercalcemia. Most PCs are small but lesions greater than 1 cm can exert pressure effects on adjacent structures\. Diagnosis can be challenging as PCs can mimic thyroid masses with no focal tracer uptake during most functional imaging modalities. Fine needle aspiration (FNA) can help if coupled ...
