Pathological Case

In his serially published atlas of pathology, <i>Anatomie Pathologique du Corps Humain</i> (1829–1842), French anatomist and pathologist Jean Cruveilhier (1791–1874) provided an early clinical-pathologic description of Dyke-Davidoff-Masson syndrome. Cruveilhier’s case was initially published around 1830, more than a century before the clinical and radiologic report of Dyke and colleagues in 1933 based on a series of patients studied with pneumoencephalography. Although Dyke and colleagues were apparently unaware of Cruveilhier’s prior description, Cruveilhier’s case manifested all of the key osseous and neuropathological features of Dyke-Davidoff-Masson syndrome as later elaborated by Dyke and colleagues: (1) cerebral hemiatrophy with <i>ex vacuo</i> dilation of the lateral ventricle, (2) ipsilateral thickening of the diploe of the skull, and (3) ipsilateral hyper-pneumatization of the frontal sinuses. In addition, Cruveilhier noted crossed cerebral-cerebellar atrophy in his case and correctly inferred a “crossed effect” between the involved cerebral hemisphere and the contralateral cerebellum. Cruveilhier’s pathological case from 1830 clearly anticipated both the cases reported more than a century later by Dyke and colleagues based on pneumoencephalography and the more recent case reports recognized with computed tomography or magnetic resonance imaging.

In 5% of cases in the nasopharynx of an adult can be found a neoplasm with benign or malignant nature. Clinical manifestations of such pathology are next: persistent dysfunction of the auditory tubes, nasalness and postnasal drip syndrome. Endoscopy of the nasopharynx, computed tomography of the sinuses and magnetic resonance imaging of the head are the main diagnostic criteria for detecting neoplasms in this area. The tactics of treatment depends on the dysplasia type of the pathological process and varies from endoscopic one-stage resection to chemoradiation treatment. Using the example of two clinical cases, we will consider an algorithm for diagnosis and treatment the patients.

AbstractObjective:There have been few previous reports of intraosseous schwannomas within the mandible with extension into the cranium. We report two such cases and discuss the relevant clinical features, radiological manifestations and treatment protocols.Method:Two case reports of trigeminal schwannoma of the mandible with intracranial extension, including analysis of clinical, radiological and pathological aspects.Results:Panoramic radiographs showed both tumours as multilocular radiolucencies. Solid and cystic components were seen on computed tomography and magnetic resonance imaging. The two tumours extended into the cranium through the pterygomandibular space and an obviously expanded foramen ovale.Conclusion:Trigeminal schwannoma of the mandible can develop to involve intracranial extension. Radiological identification of an expanded foramen ovale may facilitate pre-operative identification.

Cerebral Coenurosis

We intended to describe a case of cerebral coenurosis in a long-tailed goral, Naemorhedus caudatus, from Hwacheon-gun, Gangwon-do (Province), in the Korea. The goral, a 10-year-old male, was suffering from neurological symptoms, such as turning the circle to one side without lifting the head straight, and died at 30 days after admission to the wildlife medical rescue center in Chuncheon-si, Gangwon-do. A fluid-filled cyst was detected in the left cerebral hemisphere by computed tomography and magnetic resonance imaging. The cyst removed from the deceased goral was transparent, about 3×3 cm in size, contained a clear fluid and approximately 320 protoscolices invaginating from the internal germinal layer. The protoscolex had 4 suckers and a rostellum with 28 hooklets arranged in 2 rows. By the present study, a case of cerebral coenurosis was first confirmed in a long-tailed goral, N. caudatus, from Gangwon-do, in Korea. The residents frequently exposed in the sylvatic environment should be careful the accidental infections of zoonotic metacestode of Taenia multiceps, Coenurus cerebralis, in Korea.

Intraoral Approach

The incidence ranging of the dermoid and epidermoid cysts on the head and neck, from 1.6 to 7.0%, and they represent less than 0.01% of all oral cavity cysts. Histologically, they can be further classified as epidermoid, dermoid or teratoid. We analyzed two rare cases of large epidermoid cysts of the floor of the mouth, with sublingual as well as submental component resembling plunging ranula. Two female patients (age 15 and 16 y. o.), who’s had sublingual and submental swellings of oral floor with breathing and swallowing difficulties. The suspected clinical diagnosis of the sublingual dermoid or epidermoid cysts were supported by the radiological finding after performing ultrasonography (USG), computed tomography (CT) and magnetic resonance imaging (MRI). On the radiological investigation the differentiation between epidermoid cysts, ranulas, cystic tumours, mucous extravasation phenomena and hygromas sometimes indistinguishable, leading in the determination of internal component differentiation and has pathognomonic signs to differentiate. The lesions were surgically excised using an intraoral approach. Microscopic examinations revealed a dermoid cyst of the epidermoid type.

Case reports detailing diagnosis and effective treatment of pisotriquetral loose bodies are scarce. This article describes an even rarer case of bilateral pisotriquetral joint loose bodies, explores the relative diagnostic roles of magnetic resonance imaging versus computed tomography, and outlines effective strategies used for the management of this condition drawn from the literature and our own experience.

Abstract BackgroundHemangioblastoma in the kidney is rare. Although a few renal hemangioblastoma cases have been reported, the content of these articles mainly focused on clinical and pathological research, with minimal descriptions of radiologic findings. Moreover, there are no descriptions of magnetic resonance imaging with enhancement for this condition. We herein report two cases of renal hemangioblastoma with computed tomography and magnetic resonance imaging findings.Case presentationTwo patients presented to our institution due to dull pain of the left abdomen, and a mass in the left kidney was found by ultrasound examination in each case. They had no special family history. Physical examination revealed no obvious tenderness or percussion pain in the renal region and ureteral walking area, and there was no obvious mass. Routine blood and urine tests were normal, and serum tumor markers were negative. No obvious lesions were found on imaging of other body parts. Similar radiologic findings were observed in both cases and mimicked those of cavernous hemangiomas of the liver, including peripheral nodular enhancement in the corticomedullary phase, progressive centripetal enhancement in the nephrographic and delayed phases, and occasional complete “filling in” in the delayed phase. Given the suspicion for renal cell carcinoma, both patients underwent partial nephrectomy. The pathological results showed renal hemangioblastoma.ConclusionsRenal hemangioblastoma is a rare benign tumor that is easily misdiagnosed as clear cell carcinoma. Characteristic computed tomography and magnetic resonance imaging manifestations may improve preoperative diagnostic accuracy to avoid surgery or indicate nephron-sparing surgery.
