- Deep venous thrombosisPublication . Belo-Oliveira, P; Rodrigues, H; Belo-Soares, P; Pinto, EA 57 years old female presented to the emergency room with complains of pain and swelling of the right thigh and calf. There was associated increased warmth, redness, and tenderness of these areas.
- Detection of axillary metastases in breast cancer patients using ultrasound and colour Doppler combined with fine needle aspiration cytologyPublication . Lemos, S; Dias, M; Gonçalo, Manuela; Pinto, E; Fernandes, G; Oliveira, CFThe aims of this study were to evaluate the diagnostic value of ultrasonography and colour Doppler combined with fine needle aspiration (FNA) cytology for the detection of non-palpable axillary lymph node metastases in breast cancer patients. Forty patients with operable breast cancer (T1/T2), invasive carcinoma, not submitted to neo-adjuvant therapy, underwent axillary ultrasonography and colour Doppler preoperatively. FNA cytology was performed on axillary lymph nodes presenting ultrasonographic and/or Doppler suspicious features. A total of 542 lymph nodes were surgically removed from the 40 patients; 19 were metastatic lymph nodes. Ultrasound-guided FNA detected metastases in six out of 11 histologically node-positive patients. Sensitivity and specificity in this preliminary study was 55% and 100%, respectively. These are the preliminary results of a prospective study that has the purpose of reducing the sentinel node procedures in breast cancer patients with clinically negative axillae, but positive FNA cytology.
- Diagnostic value of ultrasound and color Doppler in identifying axillary lymph node metastases in patients with breast cancerPublication . Couto, D; Dias, M; Gonçalo, Manuela; Pinto, E; Oliveira, CFPURPOSE: The aim of this study was to evaluate the diagnostic ability of ultrasound and color Doppler in axillary lymph node metastases of patients with breast cancer. MATERIAL AND METHODS: A prospective study including 55 patients with primitive, invasive, node negative breast cancer who underwent preoperative axillary ultrasound and color Doppler. Doppler and morphologic ultrasound criteria were applied to the identification of axillary lymph node metastases. RESULTS: The imagery study of all 55 patients identified a total of 141 nodes; 44 were considered to be positive according to established criteria. The histological examination of the axillary dissection revealed a total of 989 nodes; 77 out of 989 presented metastases; all invaded nodes belonged to 21 patients. The previous imagiologic study was positive for axillary lymph node metastases in 15 out of these 21 patients. A sensitivity of 71.4%, a specificity of 71.4%, a negative predictive value of 80.6% and a positive predictive value of 60.0% were achieved. CONCLUSION: The imagery study of the axillary region through ultrasound and color Doppler might be useful in assessing axillary lymph node metastases in patients with breast cancer.
- Hepatic arterioportal fistula: Doppler and Ultrasound findingsPublication . Belo-Oliveira, P; Vaz, O; Belo-Soares, P; Martins, M; Pinto, EA 69 years old female patient presented to our Radiology department to control a hepatic cyst that have been drained because of its great dimensions.
- Induced pneumoperitoneum in CT evaluation of peritoneal carcinomatosisPublication . Caseiro-Alves, F; Gonçalo, Manuela; Abraúl, E; Pinto, E; Oliveira, CF; Vilaça-Ramos, HBACKGROUND: Imaging of peritoneal carcinomatosis is a well-known problem even for technologies as recent as computed tomography (CT). The purpose of this study was to evaluate whether CT performed after induced pneumoperitoneum (CT-PP) could have a higher sensitivity in the detection of peritoneal implants over conventional CT. METHODS: Five patients with known ovarian malignancies underwent standard CT and CT-PP. Exploratory laparotomy was performed with a maximum interval of 7 days from the last imaging procedure. Results were prospectively compared with surgical findings on a compartment to compartment basis. RESULTS: CT-PP was well-tolerated with no serious adverse reactions registered. The anterior and visceral peritoneum, the paracolic gutters and subphrenic areas were particularly well depicted but not the pelvis which was poorly evaluated in all cases. CT-PP detected all the three cases where peritoneal carcinomatosis was present even when metastatic nodules were smaller than 2 mm; it also showed intraabdominal adhesions in two patients, an important finding that precludes the use of intraperitoneal chemotherapy. CONCLUSIONS: With CT-PP there seems to be a reduction in the threshold of detectability of peritoneal implants. The direct demonstration of intraperitoneal adhesions is an important secondary finding. Disadvantages of CT-PP are (1) it is a time-consuming method and (2) it does not evaluate all the peritoneal recesses potentially involved in peritoneal carcinomatosis.

- Placental site trophoblastic tumour: the value of transvaginal colour and pulsed Doppler sonography (TV-CDS) in its diagnosis: case reportPublication . Bettencourt, E; Pinto, E; Abraúl, E; Dinis, M; Oliveira, CFThe clinical, transvaginal sonography and colour flow mapping of one patient with placental site trophoblastic tumour is presented. Colour Doppler documented a marked increase in uterine vascularity, characterised by low diastolic flow suggestive of low resistance blood flow, without regression after completion of apparently successful chemotherapy, when negative beta-hCG plasma levels were obtained. Surgical treatment was based upon our experience with colour Doppler assessment of gestational trophoblastic tumours and a review of the literature. This case suggests that TV-CDS, performed serially, is very useful in monitoring patients during chemotherapy and in detecting residual tumour, and should greatly increase the accurancy of diagnosis of PSTT.
- Sonographic and Computed tomographic demonstration of hepatic hydatid cyst communicating with the biliary treePublication . Belo-Oliveira, P; Belo-Soares, P; Martins, M; Pinto, E; Teixeira, LA 30 years old male patient presented to the emergency room with a three day history of right upper quadrant pain and jaundice.
