A Case of Cochlear Implantation in Patient with Incomplete Partition Type III Inner Ear Anomaly / 대한이비인후과학회지

Among the inner ear anomalies, incomplete partition type III (IP III) is a rare finding. The X-linked deafness type 3 (DFN3), the most common type of X-linked hearing loss of its kind, results from mutations in the POU3F4 gene and accounts for -50% of all families carrying X-linked non-syndromic hearing loss. Pathognomonic temporal bone deformities, recently classified as IP III, have been associated with DFN3. We report a patient with IP III carrying a mutation in the POU3F4 gene who experienced cerebrospinal fluid gusher during and after cochlear implantation.

A Case of Mediastinal Cystic Parathyroid Adenoma Presenting as Acute Pancreatitis / 대한내분비학회지

Hypercalcemia due to hyperparathyroidism is rarely associated with acute pancreatitis. But, the relationship between hypercalcemia and pancreatitis still remains controvesial. Ectopic parathyroid adenoma with cystic change is one of the rare causes of hyperparathyroidism, and is usually located in neck and mediastinum. We report a case of mediastinal parathyroid adenoma with cystic change associated with acute pancreatitis. A 54-year-old male presented with epigastric pain for 3 days. The serum calcium, phosphate, elastase were 16.8mg/dL, 1.1 mg/dL, 2772.0 ng/mL respectively and his parathyroid hormone level in serum was 651.84 pg/mL. Chest CT showed a mediastinal mass with well defined inhomogenously enhanced density located between SVC and aorta. The patient was diagnosed to hyperparathyroidism with acute pancreatitis due to mediastinal parathyroid adenoma with cystic change, and was surgically removed. The surgical biopsy showed parathyroid adenoma with cystic change. After operation his general condition was improved and serum calcium, phosphate, amylase, lipase level were normalized.
