Intracranial invasive fungal aneurysm due to Aspergillus sinusitis successfully treated by voriconazole plus internal carotid artery ligation therapy in an aged woman

@#A fungal carotid aneurysm is an infrequently occurring infectious aneurysm that is usually treated by antifungal therapy plus surgical debridement of the infected vessel. We herein report an extremely rare case involving a patient with a medical history of bladder cancer treated by Bacillus Calmette– Guérin (BCG) who developed a fungal aneurysm of the internal carotid artery and thrombosis of the superior ophthalmic vein caused by maxillary Aspergillus sinusitis. The patient was successfully treated by antifungal, anticoagulant, and antiplatelet drugs combined with internal carotid artery ligation therapy. Internal carotid artery fungal aneurysm is associated with a high mortality rate, but the present case suggests that it can be successfully treated by antifungal therapy combined with a less invasive endovascular therapy.

The imaging analysis of intracranial malignant teratomas / 中华放射学杂志

Objective To analyse the imaging characters of intracranial malignant teratomas (IMT). Methods The imaging appearances of IMT were analyzed in 15 pathologically proved IMT. MRI were performed on all the 15 cases, CT on 8 of them. Results Thirteen IMT showed as a lobular cyst solid mass with clear borders. The solid portion of IMT displayed iso (6/13) to hypointense(7/13) on T 1WI and iso (2/13) to hyperintense(11/13) on T 2WI. The heterogeneous enhancement was found in 11 cases, homogeneous in 2. Two IMT exhibited as the intrasellar solid lesions involving thalamencephalon. Calcification was found in 8 IMT on CT scan. No fat was demonstrated in the tumor on both CT and MR. Conclusion IMT displays relatively typical appearances on imaging studies. Together with the CT scan, The MR study may make the diagnosis before the operation.

Imaging Diagnosis of Cranial Extradural Empyema / 实用放射学杂志

Objective To evaluate CT and MRI for the diagnosis of cranial extradural empyema.Methods The imaging features in 4 patients with cranial extradural empyema were analyzed.Results 2 cases in frontal,1 case in frontalparietal,1 case in posterier cranial fossa,in this series of 4 cranial extradural empyemas was found homogenous enhancement of dural,and thickened meninges surrounding the empyema.In the series of 1 case show bony thickening and thin.Conclusion The CT and MR of cranial extradural empyema can well demonstrate the morphological and pathological evidence of ivolved menings.Therefore,CT and MR is the most diagnostic value in cranial extradural empyema.

Imaging Diagnosis of Skull Base Chondromas / 实用放射学杂志

Objective　To evaluate the value of CT MRI in diagnosing skull base chondromas.Methods　8 cases of skull base chondromas were analyzed with etiology,pathology,imaging fetures and differential diagnosis.5 cases were female,3 cases were male,age ranged from 25 to 48 years.The clinical presentation of 8 cases of skull base chondromas had neurologic syndrome.And 3 cases were examined with CT,MR imaging ,4 cases with MR imaging,1 case with CT scanning.Results　In this series of 8 chondromas,3 located in the cavernous sinus,2 in the clival region,2 in the region of jugular foramen,1 in the frontal cranial fossa.Intratumoral calcification was found in 4 cases with CT examination.Heterogeneous enhancement was found in 4 cases with CT examination.The margin of chondromas on CT was well defined.Conclusion　CT have a very important diagnosis values for detecting tumors on chondromas.MRI is superior to CT for delineating the growth style of the tumor and its relationship to the surrounding anatomic structures.

Imaging Diagnosis of Spinal Teratomas / 实用放射学杂志

Objective To study the imaging characters of spinal teratomas.Methods 10 cases of spinal teratomas were analyzed with clinical and radiography. 8 cases intramedullary, 2 cases extramedullary. 10 cases had MR examination. Results The location of spinal teratomas in 5 cases was in lumbar, 3 cases in thorax, 1 case in thoracolumbar, 1 case in cervical. 7 cases were multicyst type, 3 cases were singlecyst type. 10 cases of MR image showed mix signal intensity. The contrast enhancement T 1WI with fat saturation presented disappear fat signal of spinal teratomas. The teratomas heterogeneous enhancement was found in 10 cases with MR examination. 3 cases lumbosacral area of spinal teratomas united tethercord. Conclusion Neuroradiological features of spinal teratomas has specific manifestation. The T 1WI fat saturation scan is a availability nicety method for spinal teratomas.
