[Hepatobiliary scintigraphy in a case of acute cholecystitis in childhood]. / Gammagrafía hepatobiliar en un caso de colecistitis aguda en la infancia.

Acute cholecystitis is an uncommon disease in childhood. Few cases in patients under 10 years of age have been found in literature. An eight-year old male patient with no history of interest who had acute acalculous cholecystitis was reported. Ultrasonographic and isotopic studies led to the diagnosis and control of the patient's evolution.

Gammagrafía hepatobiliar en un caso de colecistitis aguda en la infancia / Hepatobiliar scintigraphy in a case of acute cholecystitis in childhood

La colecistitis aguda en la infancia es una patología muy poco frecuente. Son pocos los casos clínicos publicados en pacientes menores de 10 años. Presentamos el caso de un niño de ocho años, sin antecedentes de interés, con colecistitis aguda alitiásica. Los estudios ecográficos e isotópicos contribuyeron al diagnóstico y control de la evolución de este paciente (AU)

Metastatic follicular thyroid carcinoma to the kidney: a case report.

Clinically detectable well-differentiated metastatic thyroid cancer to the kidney is rare, with only 12 cases reported in the medical literature. The authors report a case of metastatic thyroid carcinoma to the kidney in a patient with widespread dissemination. She underwent total thyroidectomy, radical left nephrectomy, radioactive ablation with I-131, radiotherapy, and thyroid suppression therapy. Well-differentiated thyroid metastatic cancer can be amenable to treatment with successful long-term results.

[Pericardial effusion as a possible cause of false positives in I-131 radionuclide scans]. / Derrame pericárdico como posible causa de falso positivo en un rastreo con 131I.

The case of a patient who had undergone surgery for papillary carcinoma of the thyroid is reported. After administering a therapeutic 131I capsule, the radionuclide scan showed a diffuse, "halo-like" thoracic uptake in the precordial region. The patient's normal thyroglobulin levels and the characteristics of radionuclide uptake did not suggest metastasis. Chest radiography and ultrasonography identified pericardial effusion, which was attributed to hypothyroidism.

[Normally functioning ectopic thyroid in adults. Apropos of 4 cases]. / Tiroides ectópico normofuncionante en la edad adulta. A propósito de cuatro casos.

Four cases are presented of ectopic thyroid tissue in adult women who underwent for thyroid study for different motives. Radioisotopic uptake was absent in the usual thyroid location. Thyroid function was normal in every case and no psychomotor abnormalities were present. In one case, echography revealed an atrophic thyroid in the usual location in association with thyroid ectopy. The literature of thyroid ectopy was reviewed and the preponderant role of radioisotopic scan is underlined, together with thyroid echography in the imaging diagnosis of neck masses.

Metástasis coroídea de carcinoma papilar de tiroides: subtipo tall cell / Choroidal metastasis of papillary thyroid carcinoma: tall cell subtypes

Se presenta un caso de metástasis coroidea de un cáncer papilar de tiroides. La metástasis es el mecanismo más frecuente de la aparición de patología ocular maligna. Sin embargo el tumor primario más frecuente es el de la mama y del pulmón seguido por riñón, testículo, próstata e intestino. El cáncer de tiroides es raro y menos frecuente aún es que envíe metástasis a la coroides. El paciente presentaba además metástasis a huesos largos, tórax y cerebro. La lesión coroidea fue tratada con radioterapia con mal resultado
