Treatment of Laryngeal Cancer

WM Mendenhall, RJ Amdur

Hong Kong J Radiol 2001;4:116-8

Surgery and radiation therapy are the main treatment modalities for laryngeal cancer, although patients with unfavourable disease may require a combination of radiotherapy and chemotherapy. Computed tomography or magnetic resonance imaging is required to stage the cancer and decide on

Laryngeal Carcinoma

JM Henk

Hong Kong J Radiol 2001;4:119-21

The management of laryngeal cancer is reviewed in the context of the Clinical Practice Guidelines of the Coordination Committee in Clinical Oncology of the Hospital Authority. The relative merits of surgery and radiotherapy for various tumour stages is discussed. Chemotherapy


Treatment of Polycythemia Vera: A Clinical Oncology Perspective

CC Tong

Hong Kong J Radiol 2001;4:122-7

Polycythemia vera is a clonal myeloproliferative disorder. The Polycythemia Vera Study Group was established in 1967; its earliest accomplishment was to create a set of diagnostic criteria for polycythemia vera that have since proven their value. The Polycythemia Vera Study

Primary Nasal Lymphoma


Hong Kong J Radiol 2001;4:128-32

Primary nasal lymphoma is a rare disease. It shows significant variability in incidence and immunophenotypic characteristics among different geographic areas. It is relatively common, among the Chinese people and more than half of the lesions are of


A Comparison of Radiation Dose and Image Quality in Hysterosalpingography Using Conventional and High Kilovolt Techniques

BJJ Abdullah, KH Ng, P Rassiah

Hong Kong J Radiol 2001;4:133-6

Objective: To compare the dose area product, effective dose, and image quality of hysterosalpingography using conventional and high kilovolt techniques.

Patients and Methods: Image quality and patient dose were assessed for hysterosalpingography examinations performed on 30 patients at the University

High Precision Boosting of the Nasopharynx—Dosimetric Comparison of Conventional and Conformal Radiotherapy Techniques

FJ Lagerwaard, PC Levendag, A van Nimwegen, C de Pan, PJCM Nowak

Hong Kong J Radiol 2001;4:137-42

Objective: We report a 5-year local relapse-free survival of 94% for T1 to 2 nasopharyngeal carcinoma using endocavitary brachytherapy as a boost to deliver cumulative doses of 95 Gy to the nasopharynx. Brachytherapy may be less than adequate for extension

A Review of Superior Vena Cava Obstruction in Hong Kong Chinese Patients

HPS Wai, RMW Yeung, WM Sze, TK Yau, AWM Lee

Hong Kong J Radiol 2001;4:143-5

Superior vena cava obstruction is, in the majority of patients, due to the presence of a malignant tumour within the mediastinum, i.e. lung cancer and lymphoma. It is usually highly responsive to radiotherapy, regardless of the underlying tumour

A Survey of Patient Dose in Barium Enema Examination in a Hong Kong Public Hospital

SK Yu, CM Kung, YK Cheung, CF Ip, TL Chan, E Tsui

Hong Kong J Radiol 2001;4:146-9

Objectives: To determine the total dose-area product values for barium enema examinations; to determine the major dose contributor and to propose methods for reduction of patient dose without affecting the diagnostic values of the examination; and to compare the results


Computerised Tomography Appearances of Partial Lipodystrophy Syndrome in Association with Membranoproliferative Glomerulonephritis Type 2

WC Torreggiani, ID Lyburn, AC Harris, S Nicolaou

Hong Kong J Radiol 2001;4:150-2

Partial lipodystrophy is a disease in which body fat is lost in an unusual distribution, with patients often having a typically gaunt facial appearance. The disease is sometimes seen in association with mesangiocapillary glomerulonephritis type 2. We describe the computerised

Postvaricella Basal Ganglia Infarction—Early and Late Computed Tomography and Magnetic Resonance Imaging Findings

MSM Chan, YC Wong, AC Lee, PC Lau

Hong Kong J Radiol 2001;4:153-6

The case of a 9-year-old boy who developed acute neurological complications soon after varicella infection is reported. Computed tomography and magnetic resonance imaging showed bilateral basal ganglia lesions, which almost completely resolved on follow-up scans. There has been little previous

Double Pylorus with Occult Gastrointestinal Bleeding

WH Kwan, WH Yeung, TM Chan, CS Cheng

Hong Kong J Radiol 2001;4:157-9

Double pylorus denotes an accessory canal connecting the distal stomach to the duodenal cap. It is usually an acquired condition associated with peptic ulcer disease at or before the time of fistula formation. We report a patient with double pylorus

Granular Cell Tumour of the Deltoid Muscle

WC Torreggiani, PL Munk, K Al-Ismail, JX O'Connell, S Nicolaou, MJ Lee, BA Masri

Hong Kong J Radiol 2001;4:160-3

Granular cell tumour is an uncommon neoplasm that generally has a benign behaviour. It typically occurs in the head and neck. The authors describe an unusual location of this tumour within the deltoid muscle of the arm.

Management of a Non-deflating Foley Catheter During Hysterosalpingography Using Ultrasound Guidance

Y Wong, LWC Ho, WK Tso

Hong Kong J Radiol 2001;4:164-5

Foley catheters are often used during hysterosalpingography examinations for the purpose of delivering contrast. Among the list of complications with hysterosalpingography, however, the problem of a non-deflating Foley catheter balloon is rarely described. Potential factors predisposing to nondeflating balloons include

Retrograde Jejuno-jejunal Intussusception from Small Bowel Metastases

WH Luk, TKL Loke, WK Kwok, JCS Chan

Hong Kong J Radiol 2001;4:166-8

Retrograde intussusception is extremely uncommon, usually occurring as a complication of gastric surgery and long intestinal tube. We report a case of retrograde jejuno-jejunal intussusception with a lead point due to a pulmonary metastatic deposit.

Suprasellar Ependymoma

VCY Chiu, CM Chan, PTG Chan, HM Chiu, YLJ Cheung, CHS Chan

Hong Kong J Radiol 2001;4:169-72

Supratentorial ependymomas account for approximately 40% of intracranial ependymomas. We present an unusual case of supratentorial ependymoma, with both clinical and radiological features of a suprasellar tumour.
