Abstract：
According to the literature, transverse sinus hypoplasia is not a normal variant and has a serious potential effect on cerebral blood flow. We are presenting a rare case of chronic headache due to severe hypoplasia of the left transverse and sigmoidal sinus. A 12-year-old female girl was admitted with a complaint of gradual progressive severe headache, throbbing in nature, confined to a bitemporal and frontal region in the last 4-5 months. Headache is not associated with fever, vomiting, photophobia, or vision problems. The child had no history of recurrent running nose, refractory vision, ear discharge, head trauma, exanthemata rash, or any drug history. On examination, the child was conscious and oriented. Vital signs are normal. The child was neurologically normal and had no focal signs. Other systemic examinations were normal. Based on History and examination, differential diagnosis was made, like Pseudo tumor cerebri, migraine, deep vein sinus thrombosis, and functional and Posterior fossa tumor. The child had normal routine investigations like complete blood count, electrolyte, and D-dimer. The fundoscopy was normal. In MRI, brain hypoplasia of the left transverse and sinusoidal sinus was suspected and confirmed by MRI venography. Thus, for any patient in an emergency with a chronic headache without focal signs and normal fundoscopy, one deferential should be considered for transverse and sigmoid sinus hypoplasia.
摘要：
根据文献,横窦发育不全不是正常变异，对脑血流有严重的潜在影响。由于左横窦和乙状窦的严重发育不全，我们提出了一种罕见的慢性头痛病例。一名12岁的女女孩因逐渐进行性严重头痛而入院，在大自然中跳动，在过去的4-5个月中局限于双颞叶和额叶区域。头痛与发烧无关，呕吐,畏光,或者视力问题。这个孩子没有反复流鼻涕的病史，难治性视力,耳朵放电,头部外伤,皮疹,或任何药物史。在检查中，孩子是有意识和有针对性的。生命体征正常。该孩子的神经系统正常，没有局灶性体征。其他系统检查正常。基于历史和考试，进行了鉴别诊断，像假性脑瘤,偏头痛,深静脉窦血栓形成,功能性和后窝肿瘤。孩子进行了正常的常规检查，如全血细胞计数，电解质,和D-二聚体。眼底镜检查正常。在核磁共振中,怀疑左横窦和窦窦的脑发育不全，并通过MRI静脉造影证实。因此，对于任何患有慢性头痛且没有局灶性体征和正常眼底镜检查的急诊患者，横窦和乙状窦发育不全应考虑一个偏倚。
