Calcification is uncommon in chronic subdural hematoma and popularly known as calcified chronic subdural hematoma (CSSDH), and about hundred cases are reported in the form of isolated cases report. The calcified inner membrane of chronic subdural hematoma gets adherent to underlying cerebral cortex preventing re-expansion of the brain and producing mass effect. Calcification can develop in chronic subdural hematoma of traumatic origin or postmeningitic effusion or extremely rarely after shunt surgery. CCSDH is also known as armored brain or Matrioska head and those related to cerebrospinal fluid diversion ventriculoperitoneal (VP) shunt surgery, constitute one of the rare complications of shunt, and development is attributed to overdrainage of shunt. Authors report a unique case with bilateral calcified chronic subdural hematoma in an 8-year-old boy, who had VP shunt surgery for obstructive hydrocephalus at the age of 1 year of life, presented with feature of nonlocalized raised intracranial pressure; a diagnosis of suspected VP shunt malfunction was also considered; however, cranial computed tomography scan on current admission revealed the presence of bilateral calcified chronic subdural hematoma with secondary craniostenosis and managed successfully with burr-hole craniostomy and drainage of CCSDH. In a detailed PubMed and Medline search, authors could not get any publication regarding CSSDH associated with secondary craniostenosis developing following VP shunt surgery in infancy. The current case represents the first case in the Western literature developing secondary craniostenosis-associated CCSDH following shunt surgery in infancy, requiring surgical management. The clinical features, neuroimaging, and management of such rare case along with pertinent literature are reviewed briefly.
