{"title":"An Atypical Case of Thoracic Endometriosis Syndrome Mimicking Pulmonary Tuberculosis.","authors":"Victor Mhezi, Zuhura Nkrumbih, Magafu Majura","doi":"10.1155/crra/1708094","DOIUrl":"10.1155/crra/1708094","url":null,"abstract":"<p><p><b>Background:</b> Thoracic endometriosis syndrome (TES) is a rare form of endometriosis characterized by the presence of functioning endometrial tissue in the thoracic cavity. Patients are women of reproductive age, with a genetic link as a significant risk factor. Patients present with long-standing chest symptoms and signs that mimic pulmonary tuberculosis (PTB). The crucial issue for establishing the diagnosis is the cyclicity of signs and symptoms which occur along with the menstrual cycle. <b>Clinical Case:</b> A 34-year-old businesswoman had recurrent pelvic pain and heavy menses for 6 years, recurrent chest pain for 5 years, and recently coughing blood for 3 days. Symptoms peaked during menstruation. She reported a maternal grandmother with similar symptomatology. For the past 6 years, she was treated for recurrent pneumonia and PTB without improvement. Examination revealed right-sided pleural effusion and generalized pelvic tenderness. The catamenial nature of her symptoms led to a suspicion of TES, with PTB. Pleural fluid analysis showed exudative effusion, and Gene X-pert for MTB was negative. CA-125 was elevated, a nonspecific endometriosis marker. Pelvic ultrasound revealed features of pelvic endometriomas. Serial chest X-ray and CT scan showed right hydropneumothorax, lung mass, lung collapse, and pulmonary fibrosis. Multiple chest tubes were placed for the recurrent hydropneumothorax management. Exploratory laparotomy with bilateral ovarian cystectomy was done, and histology revealed ovarian hemorrhagic cysts and salpingitis. Hormonal suppression initiated as mainstay of treatment.

Contrast-enhanced ultrasound (CEUS) is a technique in which injected intravenous microbubbles can supplement the characterization of focal testicular masses through observation of real-time perfusion of the testis and the target mass.

{"title":"Focal Area of Low T2 Signal on MRI Scans in a Heterogeneous Uterine Leiomyoma Does Not Exclude the Possibility of Malignancy: A Report of Two Cases.","authors":"Siegfried Hélage, Claudia Laponche, Margaux Homps, Jean-Noël Buy, Pierre-Alexandre Just, Denis Jacob, Michel Ghossain, Élisabeth Dion","doi":"10.1155/crra/5388015","DOIUrl":"https://doi.org/10.1155/crra/5388015","url":null,"abstract":"<p><p><b>Background:</b> Uterine sarcomas are uncommon malignant tumors with a grim prognosis, accounting for less than 1% of all gynecologic malignancies. Radiological series often include a limited number of patients, and diagnostic approaches can vary. While the presence of low T2 signal intensity in leiomyomas on MRI has been proposed as a criterion to exclude sarcoma, exceptions to this rule exist. We present two cases that challenge this notion. <b>Case reports:</b> The first patient was a 48-year-old woman presenting with metrorrhagia. MRI revealed a large intramural leiomyoma characterized by extensive hypointensity on T2-weighted imaging (T2WI) and a small intraleiomyoma focus with intermediate signal intensity. Histopathological examination confirmed leiomyosarcoma. The second patient was a 51-year-old woman presenting with menometrorrhagia. MRI showed a subserosal myoma with zones of T2WI hypointensity interspersed with a region of intermediate signal intensity. Histopathological examination confirmed low-grade endometrial stromal sarcoma. In both cases, diffusion-weighted imaging (DWI) revealed an intratumoral zone of restricted diffusion, with an apparent diffusion coefficient (ADC) value ≤ 0.86 × 10^-3 mm²/s. <b>Conclusion:</b> MRI is crucial for distinguishing leiomyomas from sarcomas. We propose combining T2WI and DWI with ADC for this purpose, noting limitations in each sequence's reliability. Suggestive MRI criteria for malignancy in sarcomas are identified, emphasizing the need for comprehensive imaging analysis. In characterizing uterine smooth muscle tumors, particularly when analyzing leiomyoma variants, DWI emerges as the dominant sequence, with T2WI serving as a secondary sequence. ADC values aid in histopathological hypothesis, but caution is warranted due to overlap with benign lesions. This approach may refine preoperative diagnosis and guide therapeutic management.</p>","PeriodicalId":30326,"journal":{"name":"Case Reports in Radiology","volume":"2025 ","pages":"5388015"},"PeriodicalIF":0.0,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12048188/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144048212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
