Due to both the multiple cranial nerve injuries associated with nasopharyngeal base invasion and the proximity of the pituitary gland, it is challenging to differentiate this condition from intracranial space-occupying lesions, such as meningiomas and pituitary adenomas, in the early stages. This report describes a 37-year-old woman with bilateral nasal congestion, diplopia, hearing loss, and headache diagnosed with a large nasopharyngeal carcinoma invading the cerebellum, pons, medulla oblongata, and cervical spinal cord. CASE REPORT A 37-year-old woman with nasopharyngeal carcinoma (NPC) exhibiting extensive intracranial invasion - involving the mesencephalon, cerebellum, pons, medulla oblongata, and cervical spinal cord - was, with difficulty, diagnosed as having intracranial space-occupying lesions (meningiomas/pituitary tumors) by some renowned neurosurgical centers. She came to our hospital using a wheelchair, exhibiting vague pronunciation, decreased bilateral hearing, headache, facial numbness, diplopia, and coughing when drinking water. Following definitive diagnosis through nasopharyngeal biopsy confirming non-keratinizing carcinoma, we quickly proceeded with treatment. After receiving 6 cycles of chemotherapy with anti-PD-1 immunotherapy, followed by tomotherapy with concurrent nivolumab, the lesion was dynamically reduced, and efficacy was assessed as a complete response (CR). Therapy significantly improved her symptoms, with the holocranial headache resolving, intelligible speech restored, and facial sensation recovered. CONCLUSIONS This case highlights the importance of routinely integrating nasopharyngeal MRI and biopsy when evaluating patients with atypical cranial neuropathies.

Despite advances in surgical techniques and antimicrobial therapy, outcomes remain suboptimal in high-risk patients. Hemoadsorption using the CytoSorb® device has emerged as a potential adjunctive therapy to mitigate systemic inflammation during cardiopulmonary bypass (CPB) surgery, but its clinical benefit in IE remains under evaluation. CASE REPORT We describe a series of 4 adult patients with confirmed bacterial IE involving the aortic or tricuspid valve, all requiring urgent cardiac surgery. Each patient exhibited clinical signs of sepsis, persistent fever, elevated inflammatory markers, and vegetation on echocardiography. Intraoperatively, CytoSorb hemoadsorption was integrated into the CPB circuit. In all cases, a significant reduction in inflammatory markers (C-reactive protein, procalcitonin), lactate, and vasopressor requirements was observed within 24 hours postoperatively. Mechanical ventilation duration was below institutional averages. No patients required re-operation, mechanical circulatory support, or postoperative hemoadsorption. All were discharged between postoperative days 7 and 17, and follow-up at 6 months revealed no complications or relapses. CONCLUSIONS This case series suggests that intraoperative hemoadsorption using CytoSorb may be a beneficial adjunct in the surgical management of severe IE, particularly in patients with high inflammatory burden.

While video games are not traditionally recognized as a risk factor, the increasing popularity of interactive fitness games calls for attention to their potential health implications. CASE REPORT We present the case of a 25-year-old sedentary woman with no vascular risk factors who developed acute left-sided neck pain while performing repetitive overhead pushing and pulling movements using a resistance-based controller during gameplay with Ring Fit Adventure (Nintendo Co., Ltd.), a home fitness video game. Two days later, she experienced sudden-onset left-sided numbness and visual disturbance. Neurological examination revealed left homonymous hemianopia and hemisensory deficits. Brain MRI revealed an acute infarct in the right occipital lobe, and magnetic resonance angiography showed right posterior cerebral artery occlusion and dissection of the left vertebral artery with intramural thrombus. She underwent successful endovascular thrombectomy and intra-arterial thrombolysis, followed by dual antiplatelet therapy. Her symptoms improved markedly, and she was discharged with only mild visual field defect. Imaging at follow-up demonstrated vascular remodeling. No underlying vasculopathy or prothrombotic condition was identified. CONCLUSIONS This case highlights that even a seemingly benign fitness video game may exert sufficient mechanical stress to trigger VAD, particularly in untrained individuals.

This anomaly can be challenging during surgery, leading to intraoperative complications. Patient with right hepatic hypoplasia usually live normally without symptoms, but it can be associated with liver cirrhosis, portal hypertension, and gallstones. While the exact pathophysiological relationship between congenital hepatic hypoplasia and cholecystitis remains unclear, a few contributing factors have been proposed. These include mutations in the hepatocyte nuclear factor 1B (HNF1B) transcription, impaired gallbladder function, and gallbladder ischemia due to malposition. CASE REPORT A 70-year-old man presented with gangrenous cholecystitis and concurrent hypoplasia of the right hepatic lobe; a combination not previously documented. The patient, initially asymptomatic, presented with sharp epigastric pain and was diagnosed with acute cholecystitis through abdominal ultrasound. However, computed tomography (CT) imaging showed severe hypoplasia of the right liver lobe with associated compensatory hypertrophy of the left lobe in addition to stones in the gallbladder. Despite normal laboratory results, we think that the anomaly delayed the diagnosis until the development of cholecystitis as a complication. The patient underwent a successful laparoscopic cholecystectomy without converting to open surgery. CONCLUSIONS This case underscores the importance of recognizing anatomical variations when planning surgery. Awareness of right hepatic lobe hypoplasia can aid in timely diagnosis and appropriate management, ultimately reducing surgical risks and complications. Furthermore, we recommend performing CT in case of vague or atypical symptoms of acute cholecystitis, as well as when the gallbladder shows malposition on abdominal ultrasound (US).

CASE REPORT A 32-year-old woman presented with acute right buttock/thigh swelling, pain, and hypotension, initially diagnosed as septic shock. No predisposing factors were identified. Initial management included antibiotics and CT-guided drainage, resolving symptoms temporarily. One month later, she developed recurrent fever, chills, and a subcutaneous abscess. Repeated evaluations revealed no fistula; I&amp;D with vacuum sealing drainage (VSD) and plastic surgery-led wound closure achieved transient improvement. Three months postoperatively, purulent discharge recurred. Persistent symptoms prompted referral to a colorectal hospital. Rectal MRI identified a high complex-type anal fistula, confirmed surgically. Definitive fistula repair led to complete resolution. CONCLUSIONS Recurrent perianal infections, particularly in diabetics or obese patients, require vigilance for occult fistulas. This case highlights the bidirectional relationship between abscesses and fistulas, emphasizing that negative initial evaluations do not exclude fistula formation.

It most commonly occurs as a sequela of respiratory or gastrointestinal infections; however, in rare instances, cases may arise after snakebite envenomation. Several variants of GBS have been identified, with acute inflammatory demyelinating polyneuropathy (AIDP) being the most common, including our case. Other forms, such as acute motor axonal neuropathy (AMAN), are also more prevalent in tropical regions of Southeast Asia, as well as Central and South America. CASE REPORT A 52-year-old farmer from rural northern India presented with ascending palsy progressing for the past 3 days, along with bulbar symptoms and respiratory involvement for 1 day. He had been recently hospitalized a few weeks ago for snake-bite-associated neuroparalysis that had gradually resolved without any complications before discharge. Laboratory investigations and chest X-ray on presentation were suggestive of aspiration pneumonia, leading to initiation of empiric antibiotics. A diagnosis of AIDP variant of GBS was reached on the second day of admission, based on CSF studies showing albuminocytologic dissociation, and nerve conduction studies suggestive of axonal neuropathy in lower-limb nerves, and demyelination that was more pronounced in the lower limbs than in the upper limbs. He subsequently received a dose of IVIG, and was intubated for mixed hypoxic-hypercapnic respiratory failure. However, the worsening hemodynamic instability due to sepsis and GBS-related autonomic dysfunction, despite the antibiotic escalation and vasopressor support, eventually culminated in death. CONCLUSIONS This case underscores the importance of recognizing Guillain-Barre syndrome (GBS) as a neuroimmune sequela of snakebite envenomation, and the need for close neurological monitoring, patient and caregiver education, and physician awareness for early symptom recognition, and prompt initiation of empiric treatment to avoid delayed diagnoses and subsequent fatal complications.</p>","PeriodicalId":39064,"journal":{"name":"American Journal of Case Reports","volume":"26 ","pages":"e948917"},"PeriodicalIF":0.7,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12442504/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145058757","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}

Due to the potential space in the retroperitoneal cavity, primary retroperitoneal liposarcoma can grow to very large sizes without causing typical symptoms, frequently encasing critical vessels and organs and making resection highly challenging. Most chemotherapy drugs have limited effectiveness against RPLS, while radiotherapy dosages are significantly constrained by toxicity concerns. These limitations underscore why complete surgical resection (R0) continues to be the cornerstone of RPLS treatment and the single most important prognostic factor. While R0 resection remains the primary treatment, innovative approaches are needed to improve outcomes.

Imaging revealed tumor encasement of the left renal vessels and descending colon, with compression of the aorta and inferior vena cava.

Most reported cases of isolated SNHL in GPA involve unilateral or fluctuating hearing loss. Progressive bilateral SNHL associated with positivity for ANCA targeting proteinase 3 (PR3-ANCA), in the absence of systemic or ocular involvement, is rarely described in the literature. CASE REPORT A 36-year-old man with no significant medical history presented with sudden-onset left-sided SNHL, which was partially responsive to oral corticosteroids. Four weeks later, he developed bilateral hearing loss, tinnitus, aural fullness, and non-disabling postural instability. Audiometry revealed moderate-to-profound bilateral SNHL. Infectious and hematologic causes were ruled out. Laboratory tests showed positive PR3-ANCA, negative antinuclear antibodies (ANA), and mildly elevated inflammatory markers, including an erythrocyte sedimentation rate of 31 mm/h and a C-reactive protein level of 9.6 mg/dL.
