Bilobed Fasciocutaneous Flap Closure of Large Meningomyeloceles
(Lippincott Williams & Wilkins, 2006) Atik, B; Tan, O; Kiymaz, N; Yilmaz, N; Tekes, L
Background: Closure of large meningomyelocele defects presents a challenging problem. In this paper, the procedure and outcome of bilobed fasciocutaneous flap closure of large meningomyeloceles have been discussed. Materials and Methods: Bilobed fasciocutaneous flap was used in 20 patients with large meningomyelocele defects, the largest of which was 77 cm(2). A fasciocutaneous dissection was performed and the defect area was covered by tension-free closure. Results: In the follow-up period of 6 weeks, partial flap loss in a patient and cerebrospinal fluid leak inferior to the flap in another 2 were observed. These patients recovered by dressing without flap loss. Conclusions: Utilization of bilobed flaps for closure of large meningomyelocele defects seems to be an effective and reliable procedure, with advantages of decreased operative time, minimal bleeding, the suture lines for dura and flap not superimposed, and low morbidity.
Deep Intracranial Extension of Squamous Cell Carcinoma of the Scalp
(Wiley-liss, 2005) Etlik, Ö; Bay, A; Izmirli, M; Ugras, S; Yilmaz, N; Turan, A
We report a case of recurrent squarnous cell carcinoma (SCC) of the scalp with deep cerebral invasion in a 15-year-old girl. Plain films and CT showed extensive, full thickness, and skull destruction at the vertex. Gadolinium-enhanced MRI revealed neoplastic invasion of the meninges and both cerebral hemisphers down to the lateral ventricle. This case represents an example of (SCC) imitating a primary brain tumor by exhibiting intracranial extension.
Desmoplastic Medulloblastoma in a 48-Year Male
(Tohoku Univ Medical Press, 2004) Bayram, I; Ibiloglu, I; Ugras, S; Yilmaz, N; Harman, M
Medulloblastoma is a malignant invasive embryonal tumor of the cerebellum with preferential manifestation in children. The peak of occurrence is seven years of age Seventy percent of medulloblastomas occur in individuals Younger than 16. In adulthood, 80% of medulloblastomas arise in the 21-40 years age group. A 48-year-old male patient was admitted to the hospital with complains of headache, ataxia, morning vomitting and difficulty in speech was operated with the diagnosis of presence of mass of 4 x 7 cm size retaining a diffuse homogenous contrast in the posterior fossa. The diagnosis of desmoplastic medulloblastoma was given after histopathological examination. Immunohistochemical examination revealed that neoplastic cells showed staining with neuron-specific enolase and synaptophysin but not with glial fibrillary acidic protein. This lesion showed nodular, reticulin free-zones (pale islands) surrounded by densely packed, highly, proliferative cells. The pale regions within the tumor did not contain retictifin fibers. Desmoplastic medulloblastoma is encountered especially in adulthood. This type of tumor rarely occurs beyond the fifth decade of life. We present a case of desmoplastic medulloblastoma in a 48-year-old male. - desmoplastic medulloblastoma; adulthood; posterior fossa (C) 2004 Tohoku University Medical Press.
Metastatic Germ Cell Testicular Tumor of the Eye and Brain
(Acta Medica Belgica, 2005) Kiymaz, N; Çirak, B; Yilmaz, N
The aim of this report is to contribute to the clinical understanding of this rare combined pathology. Intraocular metastatic tumors are rarely encountered pathologies. Mostly encountered primary sites are breast, prostate, kidney, lung and skin. Testis as a primary site for orbital metastases is rather rare. Metastasis to orbit usually occurs to periorbital structures, but to vitreus is relatively rare. Here we describe a case of intraocular metastatic tumor to the vitreus originating from testicular embryonal cell carcinoma. Patient with intraocular tumor had also intracranial metastasis. He was operated on for intracranial lesion, after an uneventfull postoperative period he was discharged. 2 months later when he died, postmortem examination of the intraocular lesion reported as metastatic embryonal cell carcinoma. As a conclusion testicular embryonal cell carcinoma, eventhough rare, must be considered to metastasize to the eye.
Penetrating Intracranial Stone
(Karger, 2005) Kiymaz, N; Yilmaz, N
Traumatic intracranial foreign objects may cause cranial hemorrhage and contusion at an early stage and epileptic seizures and infections at a later stage, leading to morbidity and mortality in children. In the present study we report a case of a traumatic intracranial stone, which is a rarely encountered foreign object in intracranial traumatic injuries. Copyright (c) 2005 S. Karger AG, Basel.
Primary Hydatid Disease of Sacrum Affecting the Sacroiliac Joint - a Case Report
(Lippincott Williams & Wilkins, 2004) Yilmaz, N; Ozgocmen, S; Kocakoc, E; Kiris, A
Study Design. A case report of hydatid disease of the spine. Objective. To describe an unusual case of hydatid disease of the sacrum affecting the sacroiliac joint and to discuss imaging, differential diagnosis, and treatment. Summary of Background Data. Hydatidosis or echinococcosis affecting the spine is rare and has a characteristic geographic distribution. Signs of sacroiliac joint involvement and accompanying neurologic deficits cause difficulties in differential diagnosis of this rare condition. Methods. A case of 38-year-old female patient with low back pain and sciatica was presented. Results. Plain radiographs, computed tomography, and magnetic resonance imaging scans revealed destructive expansive lesion located on the right sacrum and extended through the right sacroiliac joint. Surgical enucleation of the cysts was performed together with mebendazole treatment and histopathologic examination confirmed hydatidosis. Conclusion. This unusual disease should be kept in mind in the differential diagnosis of sacroiliac pain and sciatica, especially in endemic areas.
Surgical Treatment Outcomes in Subdural Effusion: a Clinical Study
(Karger, 2006) Yilmaz, N; Kiymaz, N; Yilmaz, C; Bay, A
Objective: In this study, patients who underwent surgery due to subdural effusion were retrospectively analyzed. The location, depth and etiology of the subdural effusion, the surgical approach that was used and the recurrence rates were studied in these patients. Method: A total of 32 patients who were followed up and treated for subdural effusion at the Neurosurgery Clinic of the Yuzuncu Yil University School of Medicine were included in the study; 18 (56%) of the patients were male and 14 (44%) were female. The surgical techniques applied were surgical burr hole drainage, repeated subdural transaxial puncture and subduroperitoneal shunt approaches. The patients were evaluated by computerized tomography of the brain in week 1 and in the third month after surgery. Recurrences were evaluated based on radiological findings and the clinical condition of the patients. Result: The consciousness level of the patients was proportional to the mass effect of the subdural effusion. Lower recurrence rates were found in patients with a large midline shift resulting from the subdural effusion. In addition, recurrence rates were higher in patients with cerebral atrophy and lower protein content in the subdural effusion fluid. It was observed that these patients responded better to the subduroperitoneal shunt treatment. Copyright (c) 2006 S. Karger AG, Basel.
