Parathyroid cysts are rare clinical entities. They frequently present as a clinical diagnostic problem. They may mimic solitary thyroid nodules. The purpose of the study was to review the literature and present a case of a 22-year-old euthyroid woman presenting with recurrent swelling in the neck. Her complaints included choking and dysphagia. Fine-needle aspiration of the mass revealed clear, watery fluid with an extremely high level of calcium and c-terminal midmolecule parathyroid hormone assay in excess of 8000 pg/mL. Treatment consisted of neck exploration and removal of a 6 x 5-cm cystic encapsulated mass. Pathological diagnosis revealed a benign parathyroid cyst. The role of needle aspiration in diagnosing thyroid masses and the importance of parathyroid hormone assay in diagnosing parathyroid cyst are emphasized.

Subcapsular hematoma of the spleen is a rare complication of pancreatitis despite its close proximity to the pancreas. Pancreatic pseudocyst involving the tail of the pancreas may erode into the splenic hilum causing hilar vessel bleeding with subcapsular dissection and hematoma formation. The management of such complication is still controversial. It has been suggested that most of these complications spontaneously regress and therefore can be managed conservatively. A case of spontaneous splenic subcapsular hematoma resulting from pancreatitis was managed conservatively with a good outcome.
