RESUMO
INTRODUCTION: Parathyroid gland has a distinct physiologic and endocrinologic role in the body system. Primary hyperparathyroidism is the most common cause of hypercalcemia with a marked female dominance. It is characterized by hypercalcemia, hypophosphatemia and elevated parathyroid hormone. Parathyroid adenoma, parathyroid hyperplasia and parathyroid carcinoma form the differential diagnosis. Giant parathyroid adenomas are rarely symptomatic than non-giant parathyroid adenomas and parathyroid carcinoma. CASE PRESENTATION: A 41 years old previously healthy male patient with undetectable surgical and familial history presenting with left clavicle fracture by mild trauma. He was diagnosed for primary hyperparathyroidism after the finding of multiple bony lesions and elevated serum calcium and Parathyroid hormone. Preoperative imaging aided in diagnosis of a parathyroid lesion and secondary bone resorption lesions (brown tumors). After adequate medical treatment and preparation, selective right lower parathyroidectomy was held, and the final pathology came with a giant parathyroid adenoma. CONCLUSION: Primary hyperparathyroidism should be suspected when dealing with a hypercalcemic patient having osteolytic bony lesions. Distinguishing Parathyroid adenoma from carcinoma is a challenging and essential preoperative step in planning and surgical procedure.
RESUMO
BACKGROUND Bowel obstruction is a mechanical or functional obstruction of the intestines which prevents the normal movement of the products of digestion. Intestinal malrotation is one of the rarest causes of mechanical bowel obstruction. In adults, the incidence rate is 0.2%, and 15% of all patients with confirmed diagnosis remain asymptomatic throughout life. Surgery is generally required when the patient is symptomatic. CASE REPORT A 30-year-old man with multiple admissions for chronic intermittent colicky abdominal pain since childhood, was admitted for symptoms suggestive of proximal small bowel obstruction. Tomographic imaging identified a midgut malrotation and a duodenal obstruction by a non-diseased displaced appendix. Laparoscopic liberation of the duodenum and the terminal ilium was done successfully. CONCLUSIONS Intestinal malrotation is infrequently encountered in the adult population, but it should be kept in mind as a differential diagnosis whenever a case of acute intestinal obstruction in an adult presents without any significant past surgical history.
