This condition, which predominantly affects older adults, can result in a variety of complications, including bone pain, fractures, and deformities. This case report discusses the incidental discovery of monostotic Paget's disease involving the scapula, leading to brachial plexopathy in a 58-year-old female with a history of colon cancer. The patient had severe bilateral shoulder pain, predominantly on the left, for the past ten years. This pain, exacerbated by overhead activity and limiting daily functions, radiated to the upper limbs without causing weakness or sensory deficits. Clinical examination revealed 4/5 limb power and normal sensation, with significant pain on left shoulder movement and limited elevation. Radiographic investigations, including bilateral shoulder radiographs, contrast-enhanced computed tomography (CT), and cervical magnetic resonance imaging (MRI), identified no displaced fractures but showed diffuse enlargement of left shoulder muscles with fatty infiltration, medullary expansion of the scapula, and reduced left lung volume. MDP skeletal scintigraphy with SPECT/CT confirmed asymmetrical radiotracer uptake and medullary expansion in the left scapula. Further, MRI of both shoulders revealed left-sided expansion, cortical thickening, and fatty replacement of the rotator cuff and deltoid musculature due to denervation pseudohypertrophy from left brachial plexopathy. The right shoulder MRI showed rotator cuff tendinopathy and tears. The findings suggest a diagnosis of monostotic Paget's disease with secondary brachial plexopathy.</div></div>","PeriodicalId":53472,"journal":{"name":"Radiology Case Reports","volume":"20 6","pages":"Pages 2886-2890"},"PeriodicalIF":0.0,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684001","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}

The Posterior Superior Alveolar Artery (PSAA), which usually courses along the lateral wall of the maxillary sinus, is essential for supplying blood to this area. Nonetheless, variations in the PSAA's position and diameter can increase the risk of complications during and after surgery. We here report the case of a 36-year-old male patient presented for implant treatment in the posterior maxilla. A Cone Beam Computed Tomography (CBCT) scan revealed a rare anatomical variation of the large PSAA, observed bilaterally on the floor of the maxillary sinus instead of its typical lateral wall position. This unusual finding was considered in preoperative planning to prevent potential complications during implant placement. Preoperative CBCT imaging is essential in identifying uncommon anatomical variations of the PSAA to ensure safe and effective surgical outcomes in the posterior maxilla. Early identification of such variations can guide surgical planning, prevent complications, and enhance patient safety.</div></div>","PeriodicalId":53472,"journal":{"name":"Radiology Case Reports","volume":"20 6","pages":"Pages 2891-2894"},"PeriodicalIF":0.0,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143683342","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}

This organism can invade the brain directly, bypassing other organs, making early diagnosis particularly challenging. Symptoms often do not appear as distinctive early warning signs, and many patients do not experience noticeable skin lesions or systemic symptoms before neurological manifestations emerge. Balamuthia can enter the body through various routes, including the respiratory tract, skin, or gastrointestinal tract, eventually crossing the blood-brain barrier and causing aggressive encephalitis. The early symptoms of BAE are nonspecific, and the disease has an extremely high mortality rate. This report presents a 35-year-old male patient who died from Balamuthia amoebic encephalitis. The patient had a history of prolonged exposure to underground mines and consumed raw beef a week before the onset of symptoms. The infection is believed to have entered through the respiratory tract or gastrointestinal route. Diagnosis was primarily based on pathological findings, and the patient did not receive effective treatment due to delayed diagnosis, ultimately passing away approximately 2 months after the onset of symptoms. This case emphasizes the rarity and fatal nature of BAE, particularly when neurological symptoms are the first sign of infection without preceding systemic or dermatological manifestations.
