Intraventricular cavernomas (IVC) are rare entities. We report a case of incidentally detected intraventricular cavernoma (IVC) in frontal horn of the lateral ventricle in which the diagnosis was established by typical magnetic resonance imaging (MRI) features. The patient has been kept on follow up as surgical resection is not recommended in asymptomatic cavernomas. IVC should be considered in differentials of intraventricular mass to avoid unnecessary invasive diagnostic procedures and ineffi cient management of this benign lesion.

Percutaneous renal allograft biopsy is commonly performed as a protocol or diagnostic biopsy after kidney transplantation to detect rejection, recurrence of kidney disease, infection and calcineurin inhibitor (CNI) nephrotoxicity [1,2]. It is generally considered as a safe procedure under ultrasound guidance. However, some complications associated with this procedure can occur. Most common complications are minor and can be managed conservatively. Major complications can occur in about 1% of cases [3,4], which may require blood transfusion, interventional procedure or even surgical exploration. Page kidney phenomenon is one of the rare but serious complications, in which the renal parenchyma is tamponade and its perfusion is compromised as a result of haematoma formation under the renal capsule. This will lead to deterioration in kidney function and graft loss if the diagnosis and management are delayed [5]. Therefore, early recognition of page kidney phenomenon is crucial as prompt evacuation of the haematoma can prevent graft loss and allow complete recovery of renal function [6]. Here we reported two cases of page phenomenon after kidney graft biopsy in our institution. The literatures were also reviewed.

Ovarian cystic teratomas consist of germ cell tumors. They appear in female patients aged 20-40 years, comprising 15% of all ovarian neoplasms. These tumors appear in 90% of cases unilateral. Benign serous cyst-adenoma aromas represent the most common ovarian epithelial tumor, with an incidence of 42%, accounting for 83% of serous ovarian tumors. The mean diameter estimates between 5 and 35 cm, with a bilateral incidence of 35%. A collision tumor is composed of two adjacents, histological distinct
