Value of the bone scintigraphy in multiple osteochrondromatosis with sarcomatous degeneration.

Multiple osteochondromatosis can become malignant in 20% of the cases, this being more common when the lesion is multiple than when it is solitary. A male patient with multiple osteochondromatosis who had several local recurrences of secondary chondrosarcoma and who is still under follow-up by the Nuclear Medicine Department is presented. The bone scintigraphy findings were compared with the histopathologic results, and the importance of the patient's symptoms was verified when a sarcomatous transformation is suspected. The bone scintigraphy has the potential to detect malignization of the benign bone lesions. It also makes it possible to obtain whole-body images in a single examination, this being very useful to detect the presence of new bone lesions.

Valor de la gammagrafía ósea en la osteocondromatosis múltiple con degeneración sarcomatosa / Value of the bone scintigraphy in multiple osteochrondromatosis with sarcomatous degeneration

La osteocondromatosis múltiple puede malignizar hasta en un 20% de los casos, siendo mucho más frecuente que cuando la lesión es solitaria. Presentamos el caso de un paciente con osteocondromatosis múltiple que ha presentado varias recidivas locales de un condrosarcoma secundario en años sucesivos y que sigue controles gammagráficos en nuestro servicio. Los hallazgos de la gammagrafía ósea se compararon con los resultados anatomopatológicos y se comprobó la importancia de la sintomatología del paciente ante la sospecha de transformación sarcomatosa. La gammagrafía ósea puede aportar datos sobre la posible malignización de las lesiones benignas y permite obtener imágenes de cuerpo completo en una sola exploración, siendo muy útil ante la aparición de nuevas lesiones(AU)

Síndrome de Sapho. Hallazgos gammagráficos y radiológicos / Sapho syndrome. Scintigraphic and radiologic findings

Se presenta el caso de una paciente de 39 años con antecedentes personales de pustulosis palmoplantar de varios años de evolución y dolores ocasionales en la pared anterior del tórax, columna lumbar y ambas sacroilíacas. Acude por dolor esternoclavicular y en los primeros arcos costales izquierdos con tumefacción, palpación dolorosa y febrícula. Se diagnostica como síndrome de SAPHO basándonos en los hallazgos clínicos, radiológicos (TC), gammagráficos y manifestaciones cutáneas. La gammagrafía ósea es una prueba diagnóstica sensible y precoz para este síndrome que proporciona la ventaja de obtener imagen del cuerpo completo. (AU)

[SAPHO syndrome. Scintigraphic and radiologic findings]. / Síndrome de SAPHO. Hallazgos gammagráficos y radiológicos.

We present the case of a 39 year old woman with a several year long history of palmoplantar pustulosis and occasional pain in the anterior wall of the thorax, lumbar spine and both sacroiliac joints. As a consequence of low grade fever, severe sternoclavicular pain and discomfort and swelling in the first left rib arches, the patient was admitted to hospital. Based on the clinical, radiologic, scintigraphic and cutaneous findings, the SAPHO syndrome was diagnosed. Bone scintigraphy is an accurate and early diagnostic test for this syndrome which also provides the advantage of being able to obtain a whole body scan.

[Complete section of the choledochus caused by non-penetrating trauma of the abdomen. Use of minimal catheter jejunostomy]. / Sección completa del colédoco por traumatismo no penetrante de abdomen. Utilización de la yeyunostomía mínima a catéter (YMC).

A case is presented of complete section of the choledochus as the sole lesion in closed abdominal trauma. A study is made of the difficulties of an early diagnosis of this pathology, as well as techniques for intraoperative localization and repair. Emphasis is placed on the use of peritoneal lavage as a preoperative diagnostic method and Tc99m HIDA scintigraphy of the biliary tract. The surgical technique is reviewed, assuming that the most physiological and anatomic procedure is end-to-end choledochoduodenostomy using reabsorbable sutures. We recommend the use of minimal transcatheter jejunostomy (YMC) as a method for immediate replacement of bile juice and inhibition of secretion, as well as the possibility of postoperative physiological nutrition using this approach.
