We report a rare case of Plasma cell hyperplasia (PCH) of the Central Nervous System (CNS) in a 25 year old male involving the pachymeninges and brain parenchyma which was a diagnostic dilemma due to overlapping imaging features with other pathologies. On CT, there was white matter edema and gyral swelling in left parietoccipital region. The involved region showed ill-defined diffuse sheet like peripheral enhancement on post contrast CT, which was thought to be intraparencymal than pachymeningeal. On post contrast MR imaging, there was thick sheet like pachymeningeal enhancement with dural tail formation in addition to diffuse peripheral gyral enhancement and white matter edema in above location. Gross total excision of dural based lesion was done and histopathology revealed features of plasma cell hyperplasia. No evidence of recurrence was seen at six month follow-up.

Human beings are social animals. By definition ‘Social’ refers to a characteristic of humans. It refers to the interaction of person with other persons and to their collective co-existence, irrespective of whether they are aware of it or not, and whether the interaction is voluntary or involuntary. It would not be an exaggregation if we label the current era as the internet era. From emails to online shopping to films to medicine to politics, there is no field today that is untouched by Internet.

Intracranial dermoids are rare tumours of congenital origin accounting for less than 1% of all intracranial tumours. Rarely these tumours may rupture. We report the case of a 23yr old male presenting with headache and right sided weakness, revealing a sylvian fissure dermoid cyst with left MCA infarct. To our knowledge, this is the second case of ruptured dermoid cyst in sylvian fissure with the first case reported by Shinoyama M et al.

INTRODUCTION Lipomas are the most common benign mesenchymal tumours and can arise in any location where fat is found. CASE PRESENTATION We report a case of lipoma in the right thigh of a 52yearold woman of the Yoruba ethnic group in Nigeria which measured 58cm x 37 x 24.5 cm in diameter and weighed 17.5kg. This to the best of our knowledge is the largest lipoma in medical literature. She underwent radiological and other routine investigations and subsequently had wide excision surgery done. Histology confirmed the diagnosis of giant fibrolipoma. CONCLUSION Lipomas can attain enormous sizes if neglected. We support the currently preferred mode of confirming the diagnosis histologically from the surgically excised tumour specimen.
脂肪瘤是最常见的良性间质肿瘤，可发生在任何有脂肪的部位。我们报告一例尼日利亚约鲁巴族52岁女性右大腿脂肪瘤，直径58cm x 37cm x 24.5 cm，重17.5kg。据我们所知，这是医学文献中最大的脂肪瘤。她接受了放射学和其他常规检查，随后进行了广泛的切除手术。病理证实为巨大纤维脂肪瘤。结论脂肪瘤如被忽视，可发展成巨大的体积。我们支持目前首选的模式，确认从手术切除肿瘤标本组织学诊断。

A primary leiomyosarcoma in the oral cavity with bilateral renal metastasis in a 22-year-old female is reported. The tumour started during pregnancy and progressed to form a large unresectable mass post delivery. CT scan showed an extensive soft tissue lesion in the maxilla extending to the floor of the middle cranial fossa, oral cavity, parapharyngeal space and facial soft tissue. FNA and biopsy from maxilla showed a spindle cells lesion, which expressed smooth muscle actin and desmin in immunohistochemistry and was diagnosed as leiomyosarcoma. The tumour did not express estrogen and progesterone receptors, which have been reported in some uterine and extrauterine leiomyosarcomas. CT scan abdomen showed bilateral heterogeneously enhancing masses in right and left kidneys. CT guided FNA showed clusters of malignant spindle cells. The patient is being treated with chemotherapy consisting of Adriamycin 60mg (Day1) and Ifosfamide 2g (Day1 to Day3) to be given in 6 courses at an interval of 21 days. The case is interesting due its presentation in association with pregnancy and the presence of bilateral renal metastases. Renal metastases from sarcomas are very rare and have not been reported in primary leiomyosarcoma of oral cavity, which in turn is a rare tumor.

Spontaneous intramural small bowel hematoma is a rare complication of anticoagulant therapy. The authors report a case of small bowel intramural hematoma resulting from sodium Warfarin toxicity in a patient with prosthetic mitral valve. The patient presented with colicky abdominal pain, vomiting and melena. Typical findings on abdominal Sonography and MDCT with elevated INR value suggested the diagnosis. Patient was treated conservatively. The history of anticoagulant use with prolonged INR value in patients presenting with abdominal complaints should alert clinician and radiologist to look for this entity. The essence of prompt and accurate diagnosis of this condition lies in the conservative management to avoid an un-indicated surgery.

Ecchordosis physaliphora is a small, gelatinous tissue that is considered an ectopic notochordal remnant. This tissue is located in the midline of the craniospinal axis, reaching from the dorsum sellae to the sacrococcygeal region (1-4). Intracranial EP is typically found intradurally in the pre-pontine cistern, where it is attached to the dorsal wall of clivus via a small pedicle (1, 2, 5). Ecchordosis in this region are usually asymptomatic, and only a few studies have reported associated symptoms due to tumour expansion and compression of surrounding structures and extratumoral haemorrhage. To our knowledge retroclival EP with intratumoral haemorrhage has been described only once by Alkan et al. We report a case of retroclival EP with intratumoral haemorrhage in a 31 yr old female in which the diagnosis was based on CT and MR imaging.

To help to specify the diagnosis of dementia structural neuroimaging with computed tomography or magnetic resonance imaging is recommended in current guidelines. Computed tomography has many advantages in everyday clinical imaging. It is fast, robust, widely available and there are no relevant contraindications. In this short review a practical approach for imaging in dementia with multislice computed tomography is presented.

The thoracic duct is the largest lymphatic vessel of the body. With modern imaging technology metastatic involvement of the thoracic duct has been reported. So, it is important for the radiologist to be familiar with its normal appearance and anatomy. For this purpose 100 selected thoracic CT- scans were reviewed to describe the thoracic duct in the posterior mediastinum. The thoracic duct could be identified in 63% of the patients and visibility was best at the caudal parts of the posterior mediastinum. In most cases the thoracic duct measured around 2mm (range 1-4mm). This is in accordance to older studies. In conclusion the normal thoracic duct can be seen in a large portion of patients undergoing CT scans of the chest. If an enlarged thoracic duct without nodal involvement may indicate lymphatic spread needs to be adressed in further studies.

Although colonic F-18-fluorodeoxyglucose uptake is extremely common in whole-body positron emission tomography-computed tomography, direct visualization of fecal FDG accumulation in a clinical setting has not been reported. Here we report direct visualization of fecal FDG accumulation in the colostomy bag of a 75-year-old man with an 8-month history of rectal cancer. Although the mechanism of colonic FDG uptake is complex which includes both physiologic and pathologic factors, fecal FDG accumulation at least partially contributes to colonic FDG activity.
