The diagnosis and treatment strategy of occipital skull mass in hemophilic patients: a rare case report and literature review

Abstract

Background: Cranial hemophilic pseudotumor (cHPT) is a very rare disease, which is easy to misdiagnose. It is also difficult to manage such patients. We reported the first case of occipital cHPT. Case presentation: Here, we presented a rare case of an occipital bone mass in a 3-year-old boy who was diagnosed with hemophilia A. The mass was misdiagnosed as an aneurysmal bone cyst by pathological examination. After resection, the patient underwent one-stage cranioplasty. However, the patient was admitted again for hematoma caused by an invasive procedure. A second surgery and one-stage cranioplasty were performed at the same time. A follow-up 3 months after discharging showed the patient was uneventful, and the titanium mesh was well fixed. Conclusion: The diagnosis of cHPT requires the combining of history, radiological examination, and pathological examination. Resection is the best choice for symptomatic cHPT. Replacement treatment and less invasive treatment can make perioperative management safer. One-stage cranioplasty for resection of an occipital cHPT can improve the quality of life.

Numerical Analysis and Calculation for Urban Street Landscape Spatial Pattern

“…Modern people tend to have a relatively fixed choice of accommodation space on the street. Taking Guangchang East Road in Nanchang City as an example, he analyzed the factors that affect people's staying activities on the street, the types of staying space and the existing problems, and put forward some design suggestions [3]. Ghaleh M R believed that streets play a very important role as the most important factor in civic perception.…”
