Background & Importance: Cavernous angiomas are typically superficial lesionscreated by anomalous vessels and found in the skin or mucosa, but intradural locations are rare especially in the spine. We report a case of the spinal intradural Cavernous angiomas of the lumbar spine. Case Presentation: A 53-year-old man presented with a 6-month history of low back pain and bilateral radicular pai...

PURPOSE This study was performed to examine the treatment of erectile dysfunction by use of superparamagnetic iron oxide nanoparticles-labeled human mesenchymal stem cells (SPION-MSCs) transplanted into the cavernous nerve injured cavernosa of rats as monitored by molecular magnetic resonance imaging (MRI). MATERIALS AND METHODS Eight-week-old male Sprague-Dawley rats were divided into three ...

Ewing's / peripheral primitive neuroectodermal tumor (pPNET) of the cavernous sinus are extremely uncommon. We present clinical, radiological, pathological findings of Ewing's / pPNET involving the cavernous sinus in an eleven-month-old infant presenting with proptosis and 6th nerve palsy. MRI Contrast scans showed a well-defined, homogenously enhancing mass involving the right ...

The morphology of the dura mater and its relationship with the structures of the cavernous sinus were analyzed in five tufted capuchin monkeys (Cebus apella) using histological sections, showing that the walls of the cavernous sinus of this species are similar to those of other primates, including man. Except for the medial wall of the cavernous sinus, the remaining walls consist of two distinc...

OBJECTIVE To describe a patient who presented with a hypoglossal nerve palsy caused by a cavernous malformation, review the literature on cavernous malformations associated with cranial nerves and the differential diagnosis of hypoglossal palsy. RESULTS Partial resection of the lesion was achieved and the diagnosis of cavernous malformation proven histologically. CONCLUSIONS Involvement of ...

Medullary hemorrhage is rare, and the causative role of hypertension still remains controversial. Cavernous angioma and other vascular malformations have been reported to cause medullary hemorrhage. A 53-year-old man was admitted to our hospital for vertigo. Medullary hemorrhage and multiple small hypointense lesions were detected on T2-star weighted magnetic resonance imaging (T2*W MRI). One a...

Supratentorial dermoid cysts are uncommon to develop in the cavernous sinus. We present a ruptured dermoid cyst of the cavernous sinus extending into the posterior fossa. The patient was a 32-year-old female who complained occipital headache, blurred vision, and tinnitus over 4 years. Brain magnetic resonance (MR) imaging revealed an enhanced tumor in the right cavernous sinus extending into th...

Ureteral cavernous hemangiomas are an extremely rare, benign tumor. Most cavernous hemangiomas of ureter are diagnosed postoperatively by pathologic examination. A 39-year-old female patient presented with a bladder mass found incidentally by abdominal ultrasound. The patient underwent computed tomography, urine cytology, and cystoscopy. Cystoscopy showed 2 masses protruding from the right uret...

Cavernous angiomas although relatively common lesions rarely reach a large size. They have a well documented association with AVMs, capillary telangiectases and venous angiomas but are not specifically associated with intracerebral aneurysms. We present a case of what we believe to be the 4th largest reported giant cavernous angioma to present in adulthood. This cavernous angioma also happened ...

ovarian hemangiomas are benign and rare tumors of female genital tract with less than 60 reported cases in the literature. a 38- yr- old woman was admitted to be’sat hospital, tehran, iran in 2012, due to severe abdominal pain. ultrasound evaluation revealed a 6 cm left ovarian cystic mass and serum tumor markers were normal. then, left salpingo-oophorectomy was performed for the patient. micro...
