Subcutaneous Taenia crassiceps Cysticercosis Mass Excision from an 11-Year-Old Mixed-Breed Dog.

An 11 yr old mixed-breed dog presented with a 2 × 3 cm semimovable subcutaneous soft-tissue mass overlying the right hip region that grew to 8 × 5 cm over a 6 mo period. Two separate fine needle aspiration cytology samples showed marked pyogranulomatous inflammation with no cytologically apparent infectious etiology or neoplasia. Computed tomography imaging revealed a well-marginated, heterogeneous, contrast-enhancing soft-tissue mass extending into the adjacent fat, suggestive of neoplasia. A 14G needle biopsy showed similar chronic inflammatory changes without evidence of neoplasia or infectious etiology. Excisional biopsy of the mass was performed, and ex vivo sectioning revealed Taenia crassiceps cysticerci. Histopathology confirmed severe chronic pyogranulomatous cellulitis and myositis with intralesional cysticerci. Anthelmintic treatment was administered postoperatively, and no evidence of local recurrence has been noted as of 6 mo after the operation. To our knowledge, this is the first case report describing the cytological, histological, cross-sectional imaging characteristics and treatment outcome of T crassiceps cysticercosis in a dog.

Minimally invasive bone-saving orbitotomy for removal of optic nerve cysticercosis.

A 32-year-old man previously being managed for multiple neurocysticercosis presented with a reduction in vision and pain on eye movement. Fundus examination revealed disc edema with venous dilatation. MRI showed a localized hypointensity on T1 weighted images and hyperintensity on T2 weighted images suggestive of a cyst in the optic nerve sheath. Medical therapy with albendazole and steroids did not improve vision. Surgical removal of the cyst was achieved by a modified lateral orbital exploration using a lateral canthal incision without bone removal, with full recovery of vision. Histopathological examination confirmed cysticercosis.

Oral cysticercosis.

Cysticercosis is a common disease in developing countries, but oral lesions caused by this parasitic infestation are rare. We report here a rare case of oral cysticercosis in a 17 year old male who sought treatment for an asymptomatic nodule of the lower lip that had previously been diagnosed as a mucocele.

Review of cysticercosis of maxillofacial region and report of two cases.

Cysticercosis is a parasitic infection caused by the larval stage of Taenia solium, which very rarely manifests in the maxillofacial region. It usually presents as a painless swelling. The most common site for maxillofacial cysticercosis are the tongue and lips. When humans accidently ingest the eggs of Taenia solium, they become the intermediate host, a role which is typically played by pig. This paper describes two cases of cysticercosis cellulosae, presenting as non-tender swelling of left buccal mucosa and left temporalis region respectively. Case reports available on PubMed were searched and a review was performed. Excision of cystic lesion was the treatment modality in majority of published reports. It is emphasised that cysticercosis should be considered in differential diagnosis of solitary painless swellings of oral and maxillofacial region, especially in patients from an endemic region.

Muscular Cysticercosis: An Incidental Finding in the Developed World.

CASE: We present a case of muscular cysticercosis incidentally diagnosed in a patient admitted for a femoral neck fracture and submitted to total hip arthroplasty. CONCLUSION: Human cysticercosis is a parasitic infection representing a major health concern in developing countries. The clinical features are variable and depend on the anatomic location, cyst burden, cysticerci stage, and host inflammatory response. Diagnosis is commonly incidental, and prompt pattern recognition is key to diagnosis, adequate referral, and treatment. This is one of the first reports of hip arthroplasty in a patient with a history of parasitic infection (without the need for directed pathogen treatment).

Subretinal Cysticercosis in a Challenging Case: A Case Report.

Ocular cysticercosis occurs rarely and may involve various parts of the eye including subretinal space. We report a case of a 42 years-old female with diminution of vision in the right eye for one month and no vision in the left eye for 10 years. Best corrected visual acuity in the right eye was 5/60. Fundus examination showed whitish round elevated cystic mass temporal to the macula. It was confirmed as a subretinal cyst by Brightness scan and Magnetic Resonance Imaging. The subretinal cyst was removed in toto by pars plana vitrectomy followed by histopathological examination of the cyst which confirmed the diagnosis of cysticercosis. This case report highlights the importance of early diagnosis of subretinal cysticercosis which could threaten the vision in a one-eyed patient. Pars plana vitrectomy could be an effective method for subretinal cyst removal in toto even in a challenging case.

Clinico-pathological spectrum of gallbladder disease in children.

AIM: Because of wide variation in clinico-pathological spectrum of gallbladder disease in children the world over, the data of gallbladder disease from this stone belt of India were analysed. METHODS: Children who underwent cholecystectomy over a period of 8 years January 2002-December 2009 were reviewed. RESULTS: Out of 7076 cholecystectomies, 56 (0.79%) were in children. Thirty-nine (69.6%) children were 11-16 years of age. Thirty-seven (66.07%) children were girls and nineteen (33.9%) were boys. In 12 (21.4%) children, cholecystitis was acalculus. Five (8.9%) children had associated haemolytic disease and 4 (7.1%) children had congenital anomaly in the form of choledochal cyst. Ultrasound findings were available in 44 cases and showed cholelithiasis in 36 cases. Twenty-two (39.3%) children had mixed cholelithiasis, 8 (14.2%) pigment cholelithiasis, 10 (17.8%) combined cholelithiasis and 4 (7.1%) patients had small concretions. Microscopically, changes of chronic cholecystitis were seen in 98.2% while 1.7% showed acute on chronic cholecystitis. There was single unusual case of cysticercus in the wall of the gallbladder. CONCLUSIONS: The frequency of gallstone disease is 0.79%. Nonhaemolytic type of cholelithiasis is more common than haemolytic type in this region. Presence of cysticercus in the gallbladder wall in one case was an unexpected finding.

Taenia crassiceps cysticercosis in a ring-tailed lemur (Lemur catta).

Subcutaneous and intraperitoneal cysticercosis due to Taenia crassiceps was diagnosed in a 5-yr-old male ring-tailed lemur (Lemur catta) in the Madrid Zoo-Aquarium (Madrid, Spain). Under laparoscopic examination, several septated fibrous cystic structures and numerous masses of small transparent vesicles (ca. 3 mm in diameter) were observed subcutaneously and inside the peritoneal cavity. Most of the structures were extirpated but, after 2 days of postsurgical intensive care, the animal died. The loss of body weight of the animal after surgical extirpation (566 g) represented 22% of the total weight (body weight before mass removal, 2582 g). The vesicles were identified under light microscopic examination as cysticerci and by molecular diagnosis as Cysticercus longicollis, the larval form of T. crassiceps. The present report represents the first detection of T. crassiceps in the prosimian genus Lemur.

Modified intraocular lens injector assisted rescue technique for failed viscoexpression in a case of intracameral cysticercosis.

Intracameral cysticercosis is a rare disease, and surgical management with viscoexpression is the preferred technique. We discuss a novel technique for removal of anterior chamber parasitic cysts and present it as an alternative to the conventional viscoexpression. Our technique uses a custom-made assembly combining an intraocular lens (IOL) cartridge with an aspiration cannula. We compare its utility with the preexisting surgical methods.

A Case Report of An Iris Epithelial Cyst Masquerading As Iris Cysticercosis.

INTRODUCTION: Iris cysts can be primary or secondary. It is common to mistake a parasitic cyst for a benign pigment epithelial cyst. However, we report a case where a benign cyst was mistaken for a parasitic cyst. CASE: A 50-year-old gentleman was seen in our OPD with gradual, progressive, painless diminution of vision in the right eye over past 5 Months. He was found to have a cystic lesion in the iris encroaching upon the pupil. OBSERVATIONS: Ultrasound biomicroscopy showed features characteristic of cysticercosis. In-toto excision of the cyst was done and was sent for histopathological examination. Histopathology failed to reveal features consistent with cysticercosis and instead showed characteristics of epithelial cyst of the iris. CONCLUSION: Histopathological examination should be done for all cystic lesions of the iris to confirm diagnosis.

Submacular cysticercosis.

Ocular cysticercosis could involve subconjunctival space, anterior chamber, extraocular muscle, subretinal space, or vitreous. The presence of intraocular live cyst is a potential threat to visual acuity. The removal of the cyst in-toto is thus of importance to prevent inflammatory reaction and ocular damage. The presence of cysticercosis underneath the macula makes the management challenging. Herein, we describe the management of a submacular live cysticercus cyst with a good postoperative gain in visual acuity. Also, the swept-source optical coherence tomography changes are described.

Mucoceles not - Oral cysticercosis and minor salivary gland adenocarcinoma: two case reports.

A mucocele is one of the more commonly encountered disorders of the oral mucosa. It develops when a minor salivary duct is injured or blocked, resulting i n the escape of mucus into the adjacent submucosal connective tissue. We present two cases that were clinically diagnosed as mucoceles that were removed because of patient anxiety. However, histological examination revealed dissimilar and medically significant pathologies. Oral cysticercosis and salivary gland adenocarcinoma are rare diseases of the oral mucosa. It is important to consider these and other uncommon diagnoses when evaluating an oral nodule presumed to be a mucocele. We will discuss the natural history and pathogenesis of these disease processes.

Cysticercosis of soft tissue.

Cysticercosis is a systemic illness caused by dissemination of the larval form of the pork tapeworm, Taenia solium. A high prevalence has been reported from the developing countries because of the co-existence of poor sanitary conditions and domestic pig raising. Human cysticercosis occurs when eggs are ingested via faecal-oral transmission from a tapeworm host. The human then becomes an accidental intermediate host, with development of cysticerci within organs. Cysticercosis is a preventable faeco-oral transmitted infection and it is possible to prevent infection by avoiding undercooked food and pork (which is an unlikely cause in muslim countries), and, water contaminated with human faeces.

Isolated cardiac cysticercosis in an adolescent.

Cardiac cysticercosis is a rare and typically asymptomatic infection. We report a case of a young man from Cameroon with a left ventricular cyst discovered during a screening echocardiogram. Computed tomography and plain films did not reveal additional cysts. Serology was negative. The patient had the cyst surgically removed for suspected echinococcosis. Sectioning demonstrated a cysticercus. The literature on cardiac cysticercosis is reviewed.

Imaging appearance of parasitic infestations of the breast: a report of two cases and review of the literature.

Parasitic infestations of the breast are uncommon. They may occur as a part of generalized disease, or present as primary breast infestations, making diagnosis difficult. Clinically, they are difficult to differentiate from the more common breast pathologies. However, imaging plays an important role, and different modalities often help distinguish and diagnose these rare conditions.

Unusual presentation of orbital cysticercosis in subperiosteal space.

The authors describe a previously unreported case of subperiosteal orbital cysticercosis in a child. Surgical incision on the periosteum led to the extrusion of a cyst, which was confirmed histopathologically. Cysticercosis should also be considered in the differential diagnosis of subperiosteal abscess.

Cisticercosis lingual. Diagnóstico, manejo clínico y tratamiento de un caso clínico / Lingual cysticercosis. Diagnosis, clinical management and treatment of a clinical case

Objetivo: Las comunicaciones bucosinusales y buco- nasales son condiciones patológicas que se caracterizan por la presencia de una solución de continuidad entre la cavidad bucal y el seno maxilar o la cavidad nasal respectivamente. Una vez que se ha instalado una comunicación es deseable ce- rrar este defecto, evitando así la infección del seno maxilar y posibles dificultades en la deglución, fonación y masticación. Se han propuesto diferentes tratamientos para su resolución, algunos no quirúrgicos y otros quirúrgicos. Los quirúrgicos pueden realizarse desplazando tejidos locales, regionales o injertando. El presente trabajo tiene como objetivo presentar situaciones clínicas de comunicaciones bucosinusales y buco- nasales con diferentes etiologías y sus distintos tratamientos según tamaño y ubicación del defecto. Casos clínicos: Se identificaron pacientes que asistie- ron al Servicio de Cirugía Maxilofacial del Hospital Piñero presentando cuatro comunicaciones bucosinusales agudas y crónicas y una comunicación buconasal crónica. Los casos analizados fueron tratados de manera quirúrgica utilizando di- versos colgajos según tamaño y ubicación del defecto (AU)

Aim: Oroantral and oronasal communications are patho- logical conditions characterized by the presence of a solu- tion of continuity between the oral cavity and the maxillary sinus or nasal cavity respectively. Once a communication has been installed, it is desirable to close this defect, thus avoid- ing infection of the maxillary sinus and possible difficulties in swallowing, phonation, and mastication. Different treatments have been proposed for its resolution, some non-surgical and others surgical. Surgical procedures can be performed by dis- placing local or regional tissue or by grafting. The aim of this case report is to present clinical situations of oral sinus and oral nasal communication with different etiologies and their different treatments according to the size and location of the defect. Clinical cases: A group of patients who attended the Maxillofacial Surgery Service of Piñero Hospital presenting four acute and chronic oral sinus and one oronasal communi- cations were identified. The analyzed cases were treated sur- gically using different flaps according to the size and location of the defect (AU)

Subretinal Cysticercosis Extraction With Bimanual, 3-D, Heads-Up-Assisted Pars Plana Vitrectomy: Clinicopathological Correlation and Surgical Technique.

A 16-year-old male presented with blurred vision in the right eye after recent travel to Nicaragua. Funduscopic examination revealed subretinal cysticercosis superior to the optic nerve. The cyst was drained and excised using a bimanual, three-dimensional, heads-up-assisted pars plana vitrectomy without complications. Technical maneuvers for cyst extraction along with clinicopathological correlation are described. Postoperatively, the patient exhibits no signs of recurrence and has excellent vision.

Cysticercosis Masquerading as Lipo-Dermoid.

Cysticercosis is caused by the larval stage of Taenia solium (Pork tape worm). Humans are the definitive hosts where the life cycle is completed and pig is the intermediate host. Incidence in India varies from 2-38% based on the consumption of pork, general hygiene and socio-economic status of the population. The parasite on reaching the small intestine encysts itself in various tissues. Most commonly Brain, Eyes, subcutaneous tissue. Intravitreal cyst is the commonest intra ocular presentation. Death of the parasite and release of the contents of the cyst causes an intense inflammatory reaction that can be devastating. We report the condition in a nine-year-old boy who presented with mild right upper lid swelling wherein cysticercus cellulosae cyst was found within the mass of the right lateral rectus muscle. It becomes important to report this case because of the unusual site of the cyst which masqueraded as a lipo-dermoid.
