We present a case of rare pitfall in the diagnosis of an oesophageal foreign body due to the calcified vertical plate of the cricoid to highlight the need to be aware of this entity to avoid unnecessary morbidity.
A case is described of ameloblastoma of maxilla presenting with numerous calcified keratin pearls. The significance of cellular variation in relation to the behavioural potential of the ameloblastoma in general is briefly discussed.
Intubation was difficult and traumatic in a 40-year-old patient presented for emergency oesophagoscopy because the diagnosis of stylohyoid ligament calcification was not suspected. High probability of stylohyoid ligament calcification should be suspected when there is difficulty in lifting the epiglottis and fibre-optic laryngoscopy is suggested as the best way to tackle this problem to prevent trauma and possible risk of regurgitation and aspiration especially in emergency situation.
The combined epithelial odontogenic tumour represents a hybrid lesion comprising primarily areas of adenomatoid odontogenic tumour intermixed with foci of calcifying epithelial odontogenic tumour. Five such cases retrieved from the files of the Division of Stomatology, Institute for Medical Research, Kuala Lumpur, and four others from the existing literature were analysed. A mean age of 18.8 years, a female preponderance (66.7%) with a male to female ratio of 1:2 and predilection for the mandible (55.6%) were observed. All cases were treated by conservative surgery and the lack of recurrence confirmed the innocuous nature of this lesion.
Calcinosis cutis is a rare presentation and not many cases have been reported especially of idiopathic type. We are reporting a case of idiopathic calcinosis cutis of lower limbs in a 33-year old female who presented to our clinic for multiple painless swellings over her lower limbs for the past six months, without any history of trauma or infection. We have decided to observe her condition on regular follow-up and conservative management.
Tumoral calcinosis is an uncommon condition which
has been described to exist in primary and secondary
forms. A lack of awareness of this entity can lead to
unnecessary procedures and incorrect management.
We report a case of a patient on peritoneal dialysis who
presented with multiple painful joint swellings to the
orthopaedic department. An initial diagnosis of septic
arthritis was made, then revised to chronic tophaceous
gout and referred to the rheumatology unit.
The new 64-row multidetector computed tomography (CT)-assisted angiography can now detect coronary artery disease with shorter breath-hold time and at faster heart rates for symptomatic patients. We aim to determine if the 64-row scanner can also overcome limitations due to mild to moderate calcification.
Pulmonary alveolar microlithiasis (PAM) is a rare chronic disease with paucity of symptoms in contrast to the imaging findings. We present a case of a 24-year-old Malay man having an incidental abnormal pre-employment chest radiograph of dense micronodular opacities giving the classical "sandstorm" appearance. High-resolution computed tomography of the lungs showed microcalcifications with subpleural cystic changes. Open lung biopsy showed calcospherites within the alveolar spaces. The radiological and histopathological findings were characteristic of PAM.
X-ray microradiography of surgically excised breast specimens offers the possibility of morphological characterization of calcifications. When combined with digital imaging techniques there exists added potential for obtaining valuable basic quantitative morphometric information regarding differences between microcalcifications in tissues exhibiting evidence of fibrocystic change, benign and malignant tumours. A total of 157 excised breast specimens from 84 patients were microradiographed using a Softex Super Soft X-ray unit and Kodak AA high resolution industrial film. A Quantimet 570C image analysis system was used to digitize and analyse the microradiographs. Of the 157 microradiographs, 51 (from 30 patients) revealed microcalcification clusters. The existence of significant differences between the three identified categories of tissue were indicated by clustering parameters. These included the number of particles per cluster, area of clusters, maximum distance to nearest neighbour, and geometric mean distance to nearest neighbour. The distribution pattern index (DPI), another of the clustering parameters used in this study, has been observed to be a particularly powerful discriminator. The value for fibrocystic change was found to be significantly smaller (0.514) than that for benign tumour (0.796) whilst that for benign tumour was observed to be significantly larger than that for malignant tumour (0.604) at a p-value of less than 0.05 (Kruskal-Wallis one-way analysis of variance).
180 patients with end-stage renal disease (ESRD) on maintenance dialysis and those who had undergone renal transplantation were questioned retrospectively. 14 patients had consumed excessive quantities of analgesics (greater than 1 kg) prior to the institution of long-term dialysis or transplantation. Sonographic examination done on these patients indicated that 7 had renal papillary necrosis (RPN). The sonographic features were renal papillary calcifications surrounding the central sinus in a complete or incomplete garland pattern. In 5 of these patients RPN is attibutable to the excessive consumption of paracetamol. We have earlier reported 10 cases of RPN due to excessive consumption of paracetamol. Thus 15 cases of RPN attributable to paracetamol consumption (1.0-15.3 kg over a period ranging from 3 to 23 years) have been documented. It is concluded that paracetamol may assume an increasingly important role in the causation of analgesic nephropathy (AN) and ESRD.
