Abstract
Pseudohypoparathyroidism (PHP) is a group of disorders characterized by end-organ resistance to parathyroid hormone (PTH), resulting in high serum PTH, low calcium, and high phosphate levels. Among its 5 subtypes, PHP type 1a is the most common and leads to hereditary osteodystrophy, marked by short stature, short metacarpals, and electrolyte abnormalities such as hyperphosphatemia and hypocalcemia, which can cause tetany and seizures. Rarely, PHP patients can experience pathological fractures of long bones. This report discusses a 22-year-old female with PHP who presented with myoclonic seizures and bilateral hip fractures. Initial symptoms included fits, flank pain, and later, leg weakness. Diagnosis was based on clinical history, elevated serum PTH, low calcium, high phosphate, bilateral cataracts, hypothyroidism, basal ganglia calcification, and family history. Treatment began with IV calcium, followed by alfacalcidol, oral calcium, and antibiotics, leading to symptom remission. Hip fractures were managed with a POP cast and later closed reduction. The patient was discharged with calcium and 1,25 dihydroxy Vitamin D supplementation and scheduled for regular follow-up.
