Imaging studies, including a multiphasic CT angiogram, revealed a contained rupture in the distal stomach, and a cystic artery pseudoaneurysm measuring 4.2 mm. Despite the presence of a perforated ulcer, there was no significant pneumoperitoneum or hemoperitoneum, leading to a diagnosis of contained perforation. The management plan included conservative treatment with IV antibiotics, proton pump inhibitors, and monitoring of hemodynamic status. On the third day of admission, the decision was made to embolize the cystic artery, as the risk of gallbladder ischemia was deemed low. This case underscores the critical need for prompt diagnosis and intervention in patients presenting with upper GI bleeding, particularly in the elderly, where the mortality rate can be significantly high.

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. She is monitored monthly as an outpatient to assess treatment efficacy and condition progression. <b>Conclusion/Learning Points:</b> TES is a form of endometriosis involving the thoracic cavity, affecting women of reproductive age. TES may mimic PTB but symptoms correlate with the menstrual cycle (catamenial in nature). In Tanzania, diagnostic challenges persist due to its nonspecific symptoms, inadequate clinicians' awareness, and lack of treatment guideline national wide.</p>","PeriodicalId":30326,"journal":{"name":"Case Reports in Radiology","volume":"2025 ","pages":"1708094"},"PeriodicalIF":0.0,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12116124/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144162449","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}
