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}

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}

Breast amyloidomas typically present as painless masses with varying imaging characteristics ranging from nonspecific asymmetries to mammary carcinoma mimics.

While breast amyloidomas are benign lesions, there are proposed associations with systemic autoimmune and hematolymphoid disorders in the literature. This suggests the need for standardized management parameters following diagnosis, as the treatment of localized amyloidosis differs greatly from that of its systemic counterpart. To date, no consensus guidelines for follow-up or management of breast amyloidomas exist, owing to its rarity and dearth of cases in the literature. Due to the necessity of employing specific staining to establish the diagnosis, underdiagnosis and occasionally misdiagnosis may contribute to its apparent rarity.

DDMS is generally diagnosed in the paediatric age group. Neuroimaging shows skull bone thickening with cerebral hemiatrophy and hyperpneumatization of sinuses. <b>Case Presentation:</b> Here is a case of a middle-aged female presenting with a history of multiple episodes of seizure since childhood. MRI showed diffuse atrophy of the left cerebral hemisphere with hypertrophy of the contralateral hemisphere, hyperpneumatization of the left frontal sinus, and thickened calvaria, all characteristics of DDMS. Based on the history, clinical findings, and MRI reports, it was diagnosed as a case of DDMS. <b>Discussion:</b> DDMS can be due to injury to the brain, either intrauterine or during early childhood. The features can be confused with other conditions like Rasmussen encephalitis, hemiconvulsion-hemiplegia-epilepsy (HHE syndrome), Sturge-Weber syndrome, Silver-Russell syndrome, basal ganglia germinoma, Fishman syndrome, and linear nevus syndrome. Before making a diagnosis, a proper antenatal and postnatal history with early childhood presentations should be taken. Occupational therapy, physiotherapy, and seizure control improve the patient's quality of life. <b>Conclusion:</b> Though DDMS is usually diagnosed during early childhood, a few missed cases lead to later findings in life, resulting in late medical consults and affecting an individual's lifestyle. Management includes only symptomatic relief.
