Hong Kong J Radiol 2015;18:37-40

DOI: 10.12809/hkjr1414247

Patients with early local recurrence of nasopharyngeal carcinoma with close proximity to the nearby carotid artery can be offered long-term control by endoscopic nasopharyngectomy which allows complete microscopic clearance of the recurrent tumour without damaging the

Full Article

WK Tsang, MK Yuen

DOI: 10.12809/hkjr1414260

Post-traumatic postoperative osteolysis is a rare cause of recrudescence of osteolysis in previously quiescent sclerotic pagetic bone. This condition can develop rapidly following trauma and operation, and mimic sinister causes like malignancy. Awareness of this rare disease entity

Evolution of Caseating Granuloma from Tuberculous Cerebritis in the Corpus Callosum
