This poses a diagnostic dilemma regarding tuberculosis (TB) of the testis, BCG complications or a true testicular malignancy. Biochemical markers and a computed tomography (CT) scan showed no evidence of malignancy or disseminated TB. A TB-ELISpot test was negative. An ultrasound of the testis revealed a hypoechoic soft tissue lesion measuring approximately 24 × 19 mm, with internal vascularity and calcifications, causing a bulge in the testicular capsule with probable extracapsular extension. Based on the clinical suspicion of a testicular tumor, a right inguinal orchidectomy was performed. Histopathologic examination revealed isolated tuberculous orchitis with focal epididymal involvement; the spermatic cord was not involved.

In this case report, a 78-year-old man with hepatitis C virus-related liver cirrhosis and hepatocellular carcinoma who also had end-stage renal disease with temporary nephrostomy noticed blurred vision and showed a large retinal infiltrate with vitreous opacity in the right eye. In the clinical diagnosis of endogenous fungal endophthalmitis, he had an intravitreal injection of 0.1% fluconazole in 0.2 - 0.3 mL every 2 weeks four times in total, in addition to a minimum dose of oral fluconazole. One month before the ophthalmic presentation, he developed a fever and computed tomography scan showed ureterolithiasis with hydronephrosis on the right side, indicating that the renal pelvic stone fell into the ureter. He underwent nephrostomy tube insertion on the right side in the diagnosis of obstructive urinary tract infection.

In stark contrast to orthopnea, where dyspnea worsens in a supine position, POS uniquely presents with decreased blood oxygen saturation upon transitioning from lying down to standing up. This syndrome poses diagnostic challenges due to its subtle symptomatology and requires a high index of clinical suspicion for accurate identification. Herein, we present a case of a 79-year-old female with a complex medical history, notably encompassing deep vein thrombosis (DVT) and subsequent pulmonary embolism (PE) necessitating long-term anticoagulation with warfarin, a history of breast cancer status post lumpectomy and chemotherapy, hypertension, and chronic kidney disease (CKD). The patient was admitted from a living facility with persistent hypoxemia and clinical features suggestive of POS. Despite comprehensive physical examination and routine laboratory investigations, no overt abnormalities were discerned. However, echocardiography unveiled a severe patent foramen ovale (PFO) with right-to-left shunting, corroborating the diagnosis of POS. Subsequently, percutaneous closure of the PFO using the GORE CARDIOFORM septal occluder was performed, with fluoroscopy confirming successful device placement within the atrial septum. Remarkably, the patient demonstrated significant improvement in oxygenation post-procedure, prompting her discharge within 2 days. POS, though rare, holds substantial clinical significance owing to its potential to precipitate considerable morbidity and mortality. The pathophysiological basis of POS lies in the discordance between pulmonary and systemic blood flow, culminating in arterial desaturation upon assuming an upright posture. Timely recognition and intervention are imperative to mitigate symptom burden and avert the progression of associated complications. Early diagnosis facilitates the implementation of targeted therapeutic strategies, thereby alleviating dyspnea and forestalling adverse sequelae stemming from this syndrome. As such, heightened awareness among healthcare practitioners regarding the nuanced presentation of POS is paramount to expedite appropriate management and optimize patient outcomes.</p>","PeriodicalId":101328,"journal":{"name":"Journal of medical cases","volume":"15 11","pages":"335-340"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11483142/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142485140","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}
