This report describes a case of pontine capillary telangiectasia in a 43-year-old woman with a clinical diagnosis of trigeminal autonomic cephalgia. The possible association with pontine capillary telangiectasia and trigeminal autonomic cephalgia is discussed.

Introduction Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT)-like attacks are rarely reported in the pediatric population and may remain undiagnosed and under-investigated as a result. Case presentation We present a case of a 15-year-old male with intermittent, episodic, right-sided brief headaches most in keeping with SUNCT, initially diagnosed as paroxysmal hemicrania, but with no response to indomethacin. The pain was likewise not responsive to typical migraine treatments or steroids. Management and outcome Contrast-enhanced magnetic resonance imaging demonstrated a right pontine capillary telangiectasia with an associated developmental venous anomaly that was adjacent to the root of the right trigeminal nerve. Differential diagnosis included first division trigeminal neuralgia with autonomic features. The patient's pain was partially alleviated by oxygen administration and responded well to carbamazepine; he remained pain free on carbamazepine a year later. Conclusion This case highlights the diagnostic dilemma of differentiating SUNCT from trigeminal neuralgia with autonomic features, both of which are rare diagnoses in pediatric patients, and the importance of appropriate neuroimaging to rule out secondary causes in patients presenting with trigeminal autonomic cephalalgias, recognizing that abnormalities identified on neuroimaging, such as vessels adjacent to the trigeminal nerve, may not be causative findings.

Objective To systematically review the association between migraine and rosacea. Background Migraine is a complex disorder with episodes of headache, nausea, photo- and phonophobia. Rosacea is an inflammatory skin condition with flushing, erythema, telangiectasia, papules, and pustules. Both are chronic disorders with exacerbations of symptoms almost exclusively in areas innervated by the trigeminal nerve. Previous studies found an association between these disorders. We review these findings, provide a meta-analysis, and discuss possible pathophysiological commonalities. Methods A search through PubMed and EMBASE was undertaken for studies investigating the association between all forms of migraine and rosacea published until November 2016, and meta-analysis of eligible studies. Results Nine studies on eight populations were identified. Studies differed in methodology and diagnostic process, but all investigated co-occurrence of migraine and rosacea. Four studies were eligible for meta-analysis, resulting in a pooled odds ratio of 1.96 (95% confidence interval 1.41-2.72) for migraine in a rosacea population compared to a non-rosacea population. Conclusion Our meta-analysis confirmed an association in occurrence of migraine and rosacea. Future studies should specifically investigate possible shared pathophysiological mechanisms between the two disorders.

Hereditary hemorrhagic telangiectasia is a rare autosomal-dominant condition affecting visceral blood vessel development. Cerebral and most commonly pulmonary arteriovenous malformations are found in the majority of symptomatic patients. The most common complications include embolic strokes and cerebral abscesses, which have been attributed to abnormal vessel communications. Platypnea orthodeoxia is a rare condition that presents dyspnea and oxygen desaturation when adopting an upright position and is relieved on decubitus. The association between hereditary hemorrhagic telangiectasia, pulmonary arteriovenous malformations, and platypnea orthodeoxia has been described in medical literature; however, orthodeoxia as a single entity without platypnea has not been described yet, especially associated with complications of this hereditary condition. We present the case of a 38-year-old male with persistent headaches, in whom a cerebral lesion was detected. Orthostatic tachycardia and severe orthodeoxia without platypnea were evidenced during physical examination. The patient was subsequently diagnosed with hereditary hemorrhagic telangiectasia and underwent cerebral abscess drainage as well as transcatheter endovascular closure of multiple pulmonary arteriovenous malformations. For this reason, the concept of platypnea orthodeoxia syndrome needs further revision. Patients presenting refractory hypoxemia should warn physicians to initially evaluate their oxygen saturation measurements during standing and decubitus position, even though platypnea may not be present.

Intracranial vascular malformations range from incidental asymptomatic vascular alterations up to life-threatening vascular disorders. Arteriovenous malformations and dural arteriovenous fistulas are cerebral vascular malformations with arteriovenous shunting of blood. In the majority of cases they are accompanied by an elevated risk of intracerebral hemorrhage and can cause severe symptoms. They can be treated conservatively or interventionally via microneurosurgery, endovascular embolization and radiation therapy. Cavernous malformations, developmental venous anomalies (DVA) and capillary telangiectasia are cerebral vascular malformations without arteriovenous shunting. Cavernous malformations are rarely symptomatic in the form of cerebral hemorrhage, headache or seizures and in such cases an operative treatment can be indicated. The DVA and capillary telangiectasia are usually asymptomatic and do not require treatment.
