The article presents a case study of a 32-year-old man with a rare manifestation of port-wine stain (PWS), characterized by rapid hypertrophy and nodularity indicative of a combined capillary-lymphatic-arteriovenous malformation (CLAVM). It mentions that the patient, who had a purple macule since birth, developed additional nodules and discharges, leading to a diagnosis through imaging and biopsy.

Dural venous sinus cysts are very infrequent lesions, generally asymptomatic and incidental. These cystic lesions may include venous structures continuing with superficial cortical veins. A 23-year-old male patient presented with a severe headache. Cranial computed tomography and contrast-enhanced magnetic resonance imaging demonstrated a well-defined, central curvilinear enhanced lesion, located in the superior sagittal sinus which was compatible with the intraluminal dural venous cyst. The patient was included imaging follow-up for possible growth of this cystic lesion. Dural venous sinus cysts are asymptomatic lesions by far. However, these incidental lesions should be followed up just in case the progression-occlusion of the dural sinus. Possible venous components that may have connections with cortical veins should be considered in terms of surgery. [ABSTRACT FROM AUTHOR]
