Purpose: To present the success of novel method for management of CONJUNCTIVAL ORBITAL inclusion CYSTs following enucleation after using trichloroacetic acid injection technique.Methods: A 20% TCA solution was injected to treat 6 cases of ORBITAL conjuctival CYST in anophthalmic socket.Results: All the patients were treated successfully. The follow-up interval was 1-7 years. No recurrence or other complications developed.Conclusion: Intralesional TCA injection is successful in resolving the problematic CYST without surgical intervention in an anophthalmic orbit. It is a safe procedure and recommended for treatment of ORBITAL conjuctival CYST.

We describe a 72 years old lady with chief complain of headache, ptosis, partial 3rd nerve palsy and visual loss of left eye, biochemistrywas normal except to mild hyperglycemia, work up of vasculitis was negative with normal E.S.R. MRI showed sphenoid mucocel, orbit at sign was improved with nasal endoscopic drainage of mucocel.      

PURPOSE: to introduce five different type of ORBITAL involvement by hydatid CYST in 8 consecutive patients.DESIGN: descriptive case series.METHODS: Herein 8 patients with slowly progressive proptosis from 2 to 4months earlier at their first presentation are introduced. Complete ophthalmic examinations were done. Complete blood count, serologic test, ESR (erythrocyte sedimentation rate), CT scan and MRI were requested. Surgical removal of the lesions performed in all patients.RESULT: The hydatid CYSTs found in the extraconal (2 patients) and intraconal space (3 patients), lacrimal gland (1 patient), medial rectus (1 patient) and intraosseous of ORBITAL wall (1 patient). The diagnosis of the isolated ORBITAL hydatid CYST without any lesion in other parts of the body was confirmed in all patients. The recurrence was not observed in any patients during 2-6 years follow up.CONCLUSION: Although the most common site of involvement of ORBITAL hydatid CYST is intraconal, it can invade various locations within the orbit.

Background: This study aimed to report on the case of a child with the manifestation of ORBITAL cellulitis which was finally diagnosed as an ORBITAL hydatid CYST. Case report: The case is a 5-year-old girl with an isolated ORBITAL hydatid CYST presented with slowly progressive proptosis, deterioration of vision, chemosis, periORBITAL swelling, and palpebral edema. Evaluations for other organ involvements including liver and lung were negative. A CYSTic ORBITAL mass lesion with enhancing walls was found in ORBITAL Computed Tomography (CT) scanning. The CYST was removed completely through the upper lid crease incision and treatment continued with systemic albendazole. The patient was followed for three months with a favorable outcome. Conclusion: We should consider the diagnosis of a hydatid CYST in a child with the signs and symptoms of ORBITAL cellulitis, specifically in endemic areas.

Purpose: To report a 12-year-old patient with a rapid growing ORBITAL mass and imaging findings suggestive of rhabdomyosarcoma that was found to be dirofilariasis after mass resection. Case Report: We describe a 12-year-old patient with a rapid growing ORBITAL mass involving medial part of orbit and medial rectus muscle and imaging findings suggestive of rhabdomyosarcoma. Histopathologic examination showed the mass to be composed of granulomatous inflammation and the thread-like object to be Dirofilaria repens. The patient was well post-operation without morbidity. In this paper, we describe distinct clinical features and imaging findings of this interesting case. Conclusion: Deep ORBITAL lesions due to dirofilariasis, as in our case, is extremely rare. It is important to add dirofilariasis to the differential diagnosis of ORBITAL mass lesions. Attention to the imaging clues, as provided in this report, can be helpful.

Background: A mandibular infected buccal CYST is defined as these which occur on the buccal and distal aspects of the roots of partly or fully erupted molars with vital pulps.Case Report: In this article, two cases of mandibular infected buccal CYSTs have been described.The CYSTs are located on the buccal aspect of mandibular second premolar and second molar teeth. Both of them were vital without a past history of infection or periodontal disease. In the microscopic view both of CYSTs lined by nonkeratinized stratified squamous epithelium, a chronic inflammatory cell infiltration in adjacent connective tissue was present.According to different hypotheses, infection plays an important role in CYST formation by creating periodontal pocket and odontogenic epithelial hyperplasia. In view of clinical and microscopic findings, these CYSTs were similar to mandibular infected buccal CYST and paradental CYST.

Introduction: Hydatid CYST of lungs is mainly diagnosed by imaging procedures such as chest Roentgenogram and chest CT Scan. In endemic area, hydatid CYST may be discovered during the surgery appearing in a form which is not usually identified with typical Hydatidosis of lungs. The objective of this study was to give a description of the most important atypical radiological presentation of lung Hydatidosis.Materials and Methods: All the patients diagnosed as having pulmonary Hydatidosis through a surgical exploration were included in this study. Standard chest Roentgenograms and computed Tomographies were evaluated before the surgery for diagnosing any lung CYST or unknown lesion.Radiological findings were divided into two categories: 1-Typical Hydatid CYSTs which have already been described in literature as having imaging presentations such as intact CYST, water lily sign and crescent sign.2- Atypical Hydatid CYSTs that do not resemble any feature of typical Hydatid CYSTs as mentioned above.Results: 1614 subjects who had already been diagnosed with pulmonary Hydatidosis over a period of 28 years went under surgical operations. Seventy nine of them received standard Thoracic CT scan.Atypical CYSTs were detected in 35% of the subjects that were X-rayed by chest and in 32 of them (40.5%) who received CT Scan. The most frequent chief complaint was coughing as reported by 68 (87%) of the cases. None of the clinical and demographic findings were significantly more frequent in the subjects with atypical Hydatid CYST. The most frequent manifestation illustrated in the radiological pictures was thick cavity wall in 9 subjects (28%). Other findings were as follows: solid mass in 7 (21%), abscess in 6 (18%), consolidation in 3 (9%), fungus ball in 3 (9%), collapse (atelectasis) in 2 (6%) and round pneumonia in 2 (6%). Cavity was significantly more frequently seen in the right lung (90%) and mass like opacity was significantly more frequent in the lower lung field (100%).Conclusion: Hydatid CYST showing atypical features is relatively common; thus, physicians should be cautious about the possibility of Hydatid CYST while evaluating most of the radiological pictures of the lung, no matter what the localization, size and count of the lesion.
