Computed tomography in prognostic stroke evaluation.

BACKGROUND AND PURPOSE: Computed tomography is now routinely used in many hospitals to investigate cerebrovascular disease. The purpose of our prospective study was to determine whether cranial computed tomography in connection with neurological assessment was useful in prognostic evaluation of survival after acute stroke. METHODS: Two-hundred forty-five consecutive stroke patients were included in the project during a 1-year period. Each had a detailed neurological assessment 24-72 hours after stroke onset and underwent cranial computed tomography without intravenous contrast injection within the first week after admission. The lesions were divided according to neuroanatomic regions. In the statistical analyses we used a multiple logistic regression model with survival/death as the binary variable. RESULTS: Computed tomography showed 76% of the patients had infarcts, 11% had hemorrhages, and 13% had no acute lesion. Forty-three patients had more than one acute lesion, and 57 had one or more old infarctions. The temporal, parietal, and frontal regions and the basal ganglia were most often affected. CONCLUSIONS: We conclude that age, level of consciousness, and involvement of the temporal lobe on computed tomography were factors of prognostic significance regarding survival in the acute phase.

Ureteritis cystica.

Six cases of ureteritis cystica are reported. Pathogenesis and diagnosis are discussed emphasizing the papillary tumour as an important differential diagnosis. A conservative attitude is recommended with a follow-up until the intravenous urography has normalized.

[False negative mammography].

During the period 1.1.1984-31.12.1986, primary surgical treatment of 423 women with palpaple, invasively progressing cancer of the breast was performed. All of these had been examined mammographically prior to operation. The uncorrected nosographical sensitivity of the mammographic investigation was 0.93, decreasing to 0.83 prior to the age of 50 years. It is emphasized that patients in whom there is a disproportion between the mammographic and palpatory findings must be referred for surgical assessment without delay.

Computed tomography and the TNM classification of lung cancer.

Computed tomography (CT) of the thorax and upper abdomen was prospectively evaluated in 84 patients with potentially operable lung cancer. Invasion into the thoracic wall and the mediastinal structures was not accurately demonstrated by CT. For metastatic mediastinal lymph nodes, the sensitivity and specificity of CT were, respectively, 86% and 61% and the positive and negative predictive indices 49% and 91%. For T1, T2 and T3 tumours the negative indices were 100%, 96% and 71%. Positive predictive index did not differ between squamous cell carcinoma and adenocarcinoma. Adrenal metastases were CT-suspected in 17 cases and liver metastases in eight, but were verified by ultrasonography in only one and four cases. CT should be used in preoperative investigation of lung cancer, irrespective of stage. Demonstration of thoracic-wall or mediastinal invasion need not exclude tumour resection. Preoperative mediastinoscopy is indicated if CT shows nodal metastases or if there are signs of tumour invasion, but not in CT-negative T1 or T2 tumour. Abdominal metastases indicated by CT should be investigated with CT-guided needle biopsy.

[Non-palpable tumors of the breast demonstrated by mammography].

During the period 1.1.1985-28.2.1987, 114 mammographic markings with needles were undertaken on cancer-suspect, non-palpable tumours of the breast in 106 patients. In 27.2% of the cases, carcinomata were found and, in 16.7%, carcinoma in situ. Mammographic examination combined with needle marking is recommended as a diagnostic supplement to clinical examination.
