Objective. To describe five cases of cranial vault metastasis. Materials and methods. Clinical records and images of five patients with cranial vault metastasis were reviewed at the "Hospital de Clinicas" and "Hospital Español" from Buenos Aires, between January 2009 to June 2010. Results. Case 1, 63 years old female, complains for headache with aleatory response to medical therapy; MRI: right occipital bone lession; Pathological Finding: breast carcinoma metastasis. Case 2, 70 years old female, complains for palpable lession of the scalp; MRI: right fronto-parietal intraxial lession and right parietal cranial vault lession; Pathological Finding: endometrial carcinoma metastasis (primary, diagnosed 4 months before). Case 3, 76 years old female, with palpable lession in the scalp; MRI: left parietal cranial vault lesion. Pathological Finding: kidney carcinoma metastasis (primary, diagnosed in 2008). Case 4, 50 years old female and Case 5, 78 years old male, both complains for bone pain; serological findings and marrow bone biopsy compatible with multiple myeloma; screening of the long bones and cranial vault demonstrate evidence of bone infiltration. Conclusion. Metastasis at the cranial vault often presents with headache or pain upon inspection of a palpable scalp lession. Images of the CNS involves CT scan (delimitate lession and differentiates litic from blastic metastasis) and MRI (shows the degree of dural and brain infiltration). Prevalence of cranial vault metastasis is greater than brain metastasis, but this underdiagnosis is due that the first are frequently course without symptoms.
