Systemic imaging of patients with suspect ocular tuberculosis include chest X-rays and computed tomography (CT) scans. Reports have suggested a role for 18 fluorodeoxyglucose-positron emission tomography/CT (FDG-PET/CT) scans. We report on the clinical utility of 18 FDG PET/CT in two patients. Case 1: A 38-year-old female patient presented with recurrent anterior uveitis. A 18 FDG-PET scan revealed metabolically active supraclavicular and chest lymph nodes. An aspiration cytology of the cervical lymph node revealed caseating granulomas suggestive of tuberculosis. Case 2: A 58-year-old female patient presented with recurrent anterior uveitis. A 18 FDG-PET scan revealed metabolically active lymph nodes in the neck. A biopsy of the cervical lymph node revealed epithelioid granulomas suggestive of tuberculosis. Both patients were started on standard antitubercular therapy with a subsequent marked reduction of activity. PET/CT scans may suggest the sites of safe high-yield biopsies.  相似文献

AIM: To explore the role of positron emission tomography-computed tomography (PET-CT) examination in the diagnosis and treatment of ocular adnexal mucosa associated lymphoid tissue lymphoma (OAML). METHODS: The general clinical data, postoperative PET-CT results, treatment regimens, and the prognosis of 21 histopathologically confirmed OAML patients between October 2017 and September 2021 were collected. Among the 21 patients, five patients underwent surgical treatment alone, 13 patients underwent surgical treatment combined with radiotherapy, and three patients underwent surgical treatment combined with chemotherapy. RESULTS: The follow-up period ranged from 8 to 79mo, with four cases of recurrence and no deaths. Through PET-CT examination, two patients exhibited both local ocular metabolic elevation and systemic metastasis, and one of these patients had cervical lymph node metastasis, while the other had submandibular and parotid gland metastasis. Nine patients showed only local ocular metabolic elevation, while 10 patients had no abnormal metabolic activity locally. CONCLUSION: PET-CT examination plays a crucial role in detecting residual lesions and recurrence following tumor resection, aiding in precise disease staging, and facilitating the development of personalized treatment plans, ultimately improving patient prognosis.  相似文献

Background: Sebaceous carcinoma (SbCC) is a rare malignancy that often mimics benign conditions. Lymphatic involvement, large T3 tumors herald a dismal survival for patients. We present our series of 13 cases of locally advanced SbCC of the eyelid treated at a surgical oncology unit and describe the clinical profile, patterns of nodal spread and recurrence pattern in this subset of SbCC.

Methods: A retrospective analysis of case records was carried out for patients presenting with orbital tumors between January 1997 and April 2010 in the department of Surgical Oncology, AIIMS, New Delhi, India. All patients underwent orbital exenteration and superficial parotidectomy with neck dissection was added to patients with clinically significant lymphadenopathy. All patients who underwent OE after 2002 were advised radiotherapy as adjuvant therapy. The end point was development of recurrence or end of two year follow up period which ever occurred earlier.

Results: Thirteen patients underwent orbital exenteration. Eleven patients had clinically palpable lymphadenopathy. Ten patients (76.9%) had pathologically confirmed metastatic nodes. Parotid lymph node involvement was present in all patients (100%); two of these ten patients also had level II b cervical lymph node involvement. Recurrence was observed in seven patients (53.8%). All recurrences were loco-regional only and no systemic metastases was seen. There were only two recurrences in the group that received PORT.

Conclusions: Eyelid SbCC is a loco-regionally aggressive malignancy and adequate disease control can be achieved with combined modality approach of radical surgery followed by post operative radiotherapy.  相似文献

In 7 rabbits the drainage from the subconjunctival space to the cervical lymph nodes was observed after subconjunctival injection of 99mTc-micro-colloid. Measurements of the activity distribution were made in vivo with an Anger type camera (pho-Gamma-IV Hp, Searle Nuclear Chicago) and in vitro after dissection with a sodium iodine crystal well counter (Clinimat-200, Picker). 6 hours after the injection into the subconjunctival space of the right eye an average of 53.7% of the applied activity had drained off. A significant accumulation of activity could constantly be registrated in the cervical lymph nodes. Its amount was generally up to 2.08% of the applied total activity per animal, with a large individual spreading. In detail, activity was found in all 7 cases in the right superficial cervical lymph node, in 5 cases moreover in the right mandibular lymph node, additionally in 2 animals in the right or left deep cervical lymph node respectively and in one animal as well in the right as in the left deep cervical lymph node. Besides, in all cases high activity was registered in the right retrobulbar and subconjunctival spaces just as in the right eye. A small activity in the right optic nerve could be pointed out in three of our seven cases.  相似文献

A 55-year-old Asian Indian woman who had recurrent sebaceous gland carcinoma of the left lower eyelid with orbital extension and regional lymph node metastasis was treated with neoadjuvant chemotherapy, using a combination of carboplatin and 5-fluorouracil. Eyelid-sparing orbital exenteration was performed after 3 cycles of chemotherapy, followed by radiotherapy to the regional lymph nodes. Subsequently, 3 cycles of adjuvant chemotherapy were administered. Significant eyelid and orbital tumor volume reduction was achieved with neoadjuvant chemotherapy, making eyelid-sparing orbital exenteration possible. Chemotherapy also spared the patient from radical neck dissection. The patient had limited morbidity and was free of local, regional, and systemic disease at 26 months of follow-up.  相似文献

OBJECTIVE: The regional lymph nodes generally are believed to be the most common first site of metastasis for conjunctival malignant melanoma, but the pattern of nodal metastasis in this disease has not been well established. The goal of this study was to determine the frequency, location, and timing of regional lymph node metastasis in patients with conjunctival melanoma treated at one cancer center over four decades. DESIGN: Retrospective case series. PARTICIPANTS: Twenty-seven patients. METHODS: The clinical records of 27 patients with conjunctival malignant melanoma were reviewed retrospectively. MAIN OUTCOME MEASURES: The rates of local conjunctival recurrence, regional nodal metastasis, and distant metastasis were analyzed along with overall survival. The follow-up time ranged from 2.5 to 17 years (median, 6 years). RESULTS: Eleven patients (41%) experienced clinical regional lymph node metastasis 1.5 to 6.0 years (mean, 3.2 years) after the initial diagnosis. The involved lymphatics were the preauricular (parotid) nodes in 8 patients (73%), the submandibular nodes in 1 patient (9%), and the deeper cervical nodes in 2 patients (18%). In seven patients (26%), distant metastasis developed without evidence of prior or concurrent regional nodal disease. Patients in whom distant metastasis developed without clinical evidence of regional nodal involvement were more likely to have had local conjunctival recurrence (P = 0.03) and a higher number of local recurrences (P = 0.05) compared with patients with regional lymph nodes as the site of first metastasis. The 5- and 10-year overall survival rates were 74% and 41%, respectively. CONCLUSIONS: Regional lymph node metastasis occurred in a higher percentage of patients with conjunctival malignant melanoma than has been reported previously. Preauricular lymph nodes were most commonly involved. Distant metastasis without prior or concurrent lymph node involvement was not a rare event.  相似文献
