Variable MR findings in ovarian functional hemorrhagic cysts.

PURPOSE: To describe the magnetic resonance (MR) findings in ovarian functional hemorrhagic cysts (FHC). MATERIALS AND METHODS: A total of 21 patients with 22 FHC, proven by follow-up ultrasound (US) in 11 women and surgery in 10 women, had US and MR examinations within 24 hours. The study was limited to cysts with obvious an echogenic pattern. All patients had T2-weighted fast spin echo (FSE), T1-weighted spin echo (SE), and T1-weighted SE fat-suppressed sequences. RESULTS: Four cysts (18%) were hypointense on T1-weighted-images without and with fat suppression, and hyperintense on T2-weighted-images. Five cysts (23%) were hypointense on T1-weighted images without and with fat suppression but heterogenous on T2-weighted images. Five cysts (23%) were hypointense on T1-weighted images but showed intermediate signal intensity on T1-weighted fat suppression images and heterogenous signal intensity on T2-weighted images. Two cysts (9%) were entirely intermediate on T1-weighted images. Five cysts (23%) displayed high signal intensity occupying less than 30% of the cystic content on T1-weighted images and one cyst (5%) displayed high signal intensity occupying more than 30% of the cystic content. CONCLUSION: Despite an obvious echogenic pattern on US, 64% of FHC were hypointense on T1-weighted images and 18% were also hyperintense on T2-weighted images. Only 36% demonstrated intermediate or high signal intensity on T1-weighted images.

Extraovarian cystadenomas: ultrasound and MR findings in 7 cases.

OBJECTIVE: To describe the ultrasound and MR appearance of paraovarian cystadenomas. METHODS: We reviewed retrospectively the radiologic findings in 7 patients with surgically proven paraovarian cystic neoplasms, including 6 serous cystadenomas and 1 borderline seromucinous cystadenoma. All had ultrasound and 4 had MR preoperatively. RESULTS: On ultrasound, the ipsilateral ovary was visualized in six cases, in contact with the cyst in five and separate from it in one. On MR, the ovary and the cyst were visible in four cases, in contact in three and separate in one. Internal papillary excrescences, present at pathology in all cysts, were seen in five on ultrasound and in four on MR. CONCLUSION: Although the extraovarian location of these neoplasms is difficult to determine preoperatively by ultrasound and MR, these imaging modalities are more reliable in predicting the histology of these rare lesions and differentiating them from simple paraovarian cysts.

[Paratesticular fibrous pseudotumours]. / Pseudotumeurs fibreuses paratesticulaires.

Paratesticular fibrous pseudotumours are a rare form of benign tumour with a slow course and a difficult preoperative diagnosis. The objective of treatment is to ensure optimal testis conservation, which is possible when the diagnosis is made on intraoperative frozen section examination. The authors report a case of diffuse fibrous pseudotumour in a 23-year-old man. In the light of this case and a review of the literature, they discuss the diagnostic and therapeutic aspects of these tumours.

[Role of endoscopic gastric biopsies in the management of gastritis. A study of 250 consecutive cases]. / Intérêt de la biopsie endoscopique dans la prise en charge des gastrites: a propos de 250 cas consécutifs.

BACKGROUND: The practical role of gastric biopsy in the management of gastritis is controversial. AIM: To estimate the yield of endoscopic biopsies in the clinical, endoscopic and pathologic approach of gastritis. MATERIAL AND METHODS: Prospective study of 250 consecutive patients who underwent an upper G.I. endoscopy between July 1996 and January 1997, for upper G.I. symptoms, miscellaneous manifestations requiring an upper G.I. endoscopy or presenting a gastritis on EGD performed for other indications. Every patient had 6 biopsies: 2 in the antrum, 2 in the corpus, and 2 in an intermediate zone. RESULTS: After defining the abnormal elemental endoscopic and pathologic patterns, gastric mucosa was endoscopically normal in 57 cases (22.8%) and abnormal in the remaining of the 250 cases (77.2%). The pathologic findings were normal in 69 cases (27.6%) and abnormal in the remaining 181 cases of 250. H. pylori was found in 126 cases (50.4%), 10 cases of which (7.9%) had normal pathology. There was no significant correlation between clinical symptoms, endoscopy and pathology. There was a correlation between endoscopic abnormalities and tobacco use (P = 0.0073), NSAIDs use (P = 0.0001) and the presence of H. pylori (P < 0.0001). There was also a correlation between pathologic findings, tobacco use (P = 0.0015), NSAIDs use (P = 0.0022) and the presence of HP (P < 0.0001). On the other hand, there was a correlation between the presence of an inflammatory infiltrate in H. pylori gastritis (P = 0.0007) and its absence in NSAIDs use (P = 0.0003). The correlation between endoscopy and pathology existed only for certains patterns: erosion and ulcerations (P = 0.0002), purpuric (P = 0.033), congestion (P < 0.0001) and mosaic (0.0095). CONCLUSION: Gastric biopsy brings no important practical supplement to endoscopic examination except in revealing the presence of H. pylori. It adds nothing to endoscopy in helping explain the clinical symptoms. But it is obvious that it may reveal some serious pre-malignant dysplasia or malignant gastric lesions (maltoma, linitis plastica). This did not occur during our study.
