  • Epidermoid Cyst of the brain stem case report
    Neurosurgical Review, 1996
    Co-Authors: Kayhan Kuzeyli, Soner Duru, Ertugrul Cakir, Aydin Pekince, Savas Ceylan, Fadil Akturk
    Abstract:

    Brain stem Epidermoid Cysts are extremely rare lesions. Only nine cases have been reported. Management of the Epidermoid Cyst is decompression of Cyst contents and removal of Cyst capsule. But in some cases resection of the Cyst may result in a poor outcome because of Cyst wall adhesion into the brain stem.

  • Epidermoid Cyst originating from an intrapancreatic accessory spleen
    Journal of hepato-biliary-pancreatic surgery, 2008
    Co-Authors: Osamu Itano, Nobuyuki Shiraga, Eiichi Kouta, Hisami Iri, Katsunori Tanaka, Hiroyasu Hattori, Fumio Suzuki, Hitoshi Otaka
    Abstract:

    We report a rare case of an Epidermoid Cyst originating from an intrapancreatic accessory spleen, in a 40-year-old Japanese man with no clinical symptoms. A Cystic tumor in the pancreatic tail was detected incidentally by abdominal ultrasonography. The patient was referred to the KKR Tachikawa Hospital for further examination of the tumor. Preoperative imaging findings suggested that the tumor was an Epidermoid Cyst originating from an intrapancreatic accessory spleen. On both pre-and post-contrast computed tomography and magnetic resonance images, the solid compartment of the tumor had the same X-ray attenuation and intensity as the spleen. Upon surgical excision, the mass consisted of solid and Cystic components that were macroscopically evident on the preoperative images. Microscopic analysis revealed that the solid component was an accessory spleen in the pancreatic tail, whereas the Cystic component was lined with stratified epithelium representative of an Epidermoid Cyst. This is the thirteenth report (in English) of an Epidermoid Cyst originating from an intrapancreatic accessory spleen, and the first case to be diagnosed prior to surgery.

  • intraspinal Epidermoid Cyst diffusion weighted mri
    Neuroradiology, 2001
    Co-Authors: Mehmet Teksam, Sean O Casey, Eduard Michel, M Benson, Chip Truwit
    Abstract:

    We report a 7-year-old boy who presented with two-month history of worsening low back and right leg pain. Conventional MR images demonstrated a poorly outlined intradural mass recognized by the displacement of the conus medullaris and the nerve roots of the cauda equina at the L2–3 level. The signal intensity of the lesion was similar to CSF. There was no contrast enhancement of the lesion. Diffusion-weighted images and ADC values revealed restricted diffusion within the mass. Myelography confirmed the mass as an intradural filling defect with myelographic block at the L2–3 level. The patient underwent total surgical excision of the mass. Pathologic examination revealed the diagnosis of Epidermoid Cyst.

  • intracranial squamous cell carcinoma arising in a cerebellopontine angle Epidermoid Cyst a case report and literature review
    Medicine, 2017
    Co-Authors: Tae Hoon Roh, Yong Sook Park, Yong Gou Park, Se Hoon Kim, Jong Hee Chang
    Abstract:

    Rationale Most of the intracranial Epidermoid Cysts are benign, but malignant lesions are occasionally reported. These lesions appear as squamous cell carcinoma and carry a dismal prognosis. Here, we report a case of a primary intracranial squamous cell carcinoma arising in a cerebellopontine Epidermoid Cyst. The relevant literatures were also reviewed. Patient concerns A 53-year-old woman presented with dizziness and diplopia 9 months in duration. Magnetic resonance imaging revealed an Epidermoid Cyst in the left cerebellopontine angle and prepontine region with a focal enhancing lesion on T1-weighted gadolinium-enhanced images. Diagnoses Histopathologic diagnosis revealed squamous cell carcinoma on a background of Epidermoid Cyst. Imaging studies excluded metastases. Interventions The tumor was removed subtotally through a lateral suboccipital approach. The patient received intensity modulated radiation therapy (6720 cGy total) postoperatively. Outcomes The patient was free from recurrence of the tumor until 3 years after surgery, at which point she was lost to follow-up. The patient died 4 years after the surgery. Lessons The Epidermoid Cyst may occasionally become malignant. Finding an area of enhancement through preoperative magnetic resonance imaging can help to make a correct diagnosis. Based on the review of previous reports, surgical removal followed by radiotherapy shows the best result to treat malignant Epidermoid Cysts.

  • Epidermoid Cyst of the intrapancreatic accessory spleen producing ca19 9
    Digestive Endoscopy, 2004

    Abstract:

    We report a rare case of an Epidermoid Cyst in an accessory spleen at the pancreatic tail with producing CA19-9. A 55-year-old female was admitted to our hospital, Cancer Research Institute, Kanazawa University, for close examination of a Cystic lesion at the pancreatic tail and a high serum CA19-9-value (176 U/mL). There were almost no abdominal symptoms related to the Cystic lesion. A Cystic tumor approximately 3 cm in diameter and composed of multilocular Cysts without a protruding portion of the inner surface was found at the pancreatic tail by ultrasound sonography, computed tomography, and magnetic resonance imaging. Endoscopic retrograde pancreatography revealed that the main pancreatic duct shifted at the pancreatic tail and there was no communication between the main pancreatic duct and Cystic lesion. Based on a preoperative diagnosis of mucinous Cystic tumor, distal pancreatectomy with splenectomy was performed. Histological findings suggested an Epidermoid Cyst (3.5 × 3.0 cm) originating from an intrapancreatic accessory spleen. Immunohistochemical analysis of CA19-9 in the Epidermoid Cyst showed clear staining of the inner epithelium of the Cyst and amorphous or hyalinous Cystic contents. The serum CA19-9 value was confirmed to decline to normal 2 months after resection. Physicians should not forget this disease during differential diagnosis related to pancreatic Cystic lesions with elevated levels of serum tumor markers, such as CA19-9 or carcinoembryonic antigen, although this disease is extremely rare.
