RESUMO
The history, physical and radiologic findings, treatment and pathology in five unusual cases of hyperparathyroidism is presented. The hyperparathyroidism was caused by a large (113 grams) mediastinal adenoma in the first patient, who is alive 25 years after surgery. A parathyroid carcinoma with compression of the esophagus was documented in the second patient. This patient is alive and normocalcemic 23 years after surgical treatment. A third patient with hyperplasia returned with hypercalcemia 20 years postsurgery requiring reoperation. A fourth patient with advanced bone findings was found to have a parathyroid adenoma. The fifth case is a patient with tertiary hyperparathyroidism secondary to hypophosphatemic rickets

Radiographic computed tomography and magnetic resonance imaging are the procedures of choice in the diagnosis of patients with suspected pituitary gland abnormalities. Several cases are presented where the diagnostic value of such procedures in patients with diseases affecting the pituitary gland is demonstrated

Success in the treatment of primary hyperparathyroidism rest in the accurate localization and removal of the diseased gland or glands. Computerized tomography and nuclear imaging scans are being used to localize abnormal parathyroid tissue. In the present study, fifteen consecutive patients undergoing surgery for primary hyperparathyroidism were all subjected to these ancillary studies. Results were not revealed to the operating team. In all instances an adenoma was localized during neck exploration. CT Scan failed to localize 73% of the affected glands. Nuclear scans missed almost fifty percent of the parathyroid adenomas. The low yield of these ancillary localizing tests makes them unnecessary in the routine evaluation of patients undergoing surgery for primary hyperparathyroidism

La estenosis congénita del esófago ocurre más frecuentemente en la unión del esófago medio y el distal. Es la menos común de las anomalías que afectan el esófago y el árbol traqueobronquial. Reportamos un caso con dicha anomalía que se interpretó inicialmente como una perforación transmural posterior del esófago en un recién nacido. Este es uno de los pacientes más jóvenes dónde se ha hecho el diagnóstico

El complicado ciclo de vida de S. mansoni produce variadas manifestaciones clínicas y patológicas. Los hallazgos radiográficos reflejan los cambios patológicos causados por la reacción alérgica entre el huésped y las diferentes etapas del parásito. La fase aguda pulmonar se debe al paso de la larva a través de la trama vascular pulmonar. Las fases crónicas se manifiestan como los síndromes de hipertensión portal, hipertensión pulmonar, cianosis pulmonar y granulomas en el sistema pulmonar, gastrointestinal y retroperitoneal así como en el nervioso central y periférico
