The authors present a case-report a 43 years old, female patient presenting with an eight-year history of hypertension caused by an adrenal adenoma. Hypokalemia and supressed plasma renina confirmed the diagnosis of primary hyperaldosteronism. An abdominal computed tomography revealed a right adrenal mass. The patient was successfully treated laparoscopically. The histopathological diagnosis was adenoma. The patient had normal blood pressure within three months.

OBJETIVO: O plastrão apendicular representa 6% dos casos de apendicite aguda e seu tratamento é controverso. O objetivo do presente estudo foi avaliar os resultados obtidos com o tratamento conservador do plastrão apendicular, instituído a partir de fevereiro de 1992. MÉTODO: Foram avaliados 36 pacientes com diagnóstico clínico, laboratorial e ultrassonográfico de plastrão apendicular atendidos no Serviço de Cirurgia Geral do Hospital Universitário da Universidade de Brasília no período de 1992 a 2001. Os pacientes eram submetidos a tratamento com antibióticos e observação clínica da remissão dos sintomas. RESULTADOS: O tratamento conservador foi efetivo em 33 pacientes (92%), com remissão dos sintomas e do tumor palpável, bem como da leucocitose. Após período médio de 11,5 semanas, os pacientes foram submetidos à apendicectomia eletiva e quatro pacientes apresentaram infecção superficial de sítio cirúrgico. A análise histopatológica revelou persistência do quadro agudo em sete pacientes (21%). CONCLUSÃO: O tratamento conservador do plastrão apendicular, seguido de apendicectomia eletiva mostrou-se efetivo na maioria dos pacientes, evitando as complicações graves da abordagem cirúrgica precoce.

BACKGROUND: Accute appendicitis is one of the most common causes of acute abdominal emergency. In 6% of these patients, appendiceal mass is palpable. The management of appendicitis with a palpable mass is controvertial. The present study analyses the results of conservative management of appendiceal mass in patients admitted at the University Hospital of Brasilia between 1992 and 2001. METHODS: Thirty-six patients with clinical, laboratorial and sonography findings of appendiceal mass were evaluated and underwent conservative management based on therapy with intravenous antibiotics and close observation of appendiceal mass reduction. RESULTS: The conservative management was successful in 33 patients (93%). Three patients failed to respond and underwent appendectomy. Elective appendectomy was performed after 11.5 weeks, with a complication rate of 12%. Histopathologic analysis showed persistent acute appendicitis in seven patients (21%). CONCLUIONS: Conservative management of appendiceal mass followed by interval appendectomy seems to be safe and effective.

Lumbar hernia is defined as an abdominal passage through the posterior abdominal wall. Approximately 250 to 300 cases have been described in the literature, being quite infrequent. Untreated lumbar hernia may result in severe complications. The authors report a case of a 60 year old male patient presenting a large bowel obstruction and perfuration secundary to incarceration of descending colon within a lumbar hernia. This was diagnosed by clinical history and computed tomography. The patient was successfully treated surgically.
