Utility of color Doppler ultrasound in evaluating the status of cervical lymph nodes in oral cancer

OBJECTIVE The aim was to study the utility of color Doppler ultrasound (CDUS) in diagnosis of cervical lymphadenopathy in oral cancer patients. STUDY DESIGN In a prospective study, 70 cervical lymph nodes in 30 known primary oral cancer patients were evaluated with CDUS during a period of 8 months. The intranodal perfusion sites and vascular resistance were the key CDUS features used to differentiate between reactive and metastatic cervical lymph nodes. Histopathologic confirmations were obtained by excisional biopsy of the lymph nodes. The results of preoperative clinical palpation of cervical lymph nodes and CDUS evaluation were compared with histopathologic outcome. RESULTS Clinical evaluation suspected 61 cervical lymph nodes to be malignant. According to the CDUS, out of 70 nodes, 49 lymph nodes showed features of benign lymphadenopathy and 21 lymph nodes showed features of malignant lymphadenopathy, whereas histopathologic evaluations were in favor of reactive for 57 (81.42%) and for malignant lymphadenopathy in 13 (18.57%). CONCLUSION The CDUS evaluation was found to be highly significant with a sensitivity of 92.90% and a specificity of 84.21%, after comparing the CDUS findings with histopathologic findings.

Treating traumatic injuries of the diaphragm

Traumatic diaphragmatic injury (DI) is a unique clinical entity that is usually occult and can easily be missed. Their delayed presentation can be due to the delayed rupture of the diaphragm or delayed detection of diaphragmatic rupture, making the accurate diagnosis of DI challenging to the trauma surgeons. An emergency laparotomy and thorough exploration followed by the repair of the defect is the gold standard for the management of these cases. We report a case of blunt DI in an elderly gentleman and present a comprehensive overview for the management of traumatic injuries of the diaphragm.

Utility of Digital Volume Tomography in Maxillofacial Trauma

PURPOSE To assess the diagnostic quality of images generated using the newly developed digital volume tomography (DVT) system and comparing them with conventional images from patients with maxillofacial trauma. MATERIALS AND METHODS The study population included 22 male patients aged 18 to 60 years with a history of maxillofacial trauma. Each patient had undergone conventional radiographic and DVT examinations to analyze the number of fracture lines in the jaws and to compare the images for their diagnostic quality by an oral radiologist and a general radiologist using the χ(2) test. RESULTS A statistically significant difference was found between the number of fracture lines evaluated on the conventional radiographs and on DVT, especially for condylar head (7) and the midface (4.41 to 4.57), zygomaticomaxillary complex and Le Fort fractures, respectively. CONCLUSIONS The detection of fracture lines and visualization within the mandibular-maxillary area using DVT was superior to using conventional radiographs.

Giant cavernous hemangiomas of the brain.

Cavernous angiomas or hemangiomas or cavernomas are benign, vascular malformations of the central nervous system and classified as occult vascular brain lesions, usually present in adulthood. With the advent of computed tomography and magnetic resonance imaging, these lesions are increasingly recognized in children. We report two cases of pediatric brain cavernomas where the children presented with recurrent seizures. Imaging findings were suggestive of giant cavernous hemangioma. The lesions were excised completely and the patients recovered well without deficits with good control of seizures.

An omental teratoma in a young girl

Teratoma is the most commonly encountered germ cell tumour among the most common ovarian tumours; however, teratomas of the omentum and mesentery are extremely rare. They are usually asymptomatic or can produce compressive symptoms. The imaging features are suggestive. The present report describes such a case of primary omental teratoma encountered in a young patient, which was managed by surgical resection. The histopathological examination confirmed the diagnosis of mature cystic teratoma. Germ cell tumors are congenital tumors containing derivatives of all the three germinal layers, frequently seen in gonads. But their occurrence in extragonadal sites, such as omental teratoma, is relatively rare.

Malignant hemangioendothelioma of occipital bone

Epithelioid hemangioendothelioma is a rare vascular tumor of bone, and rarely these lesions can present as unique and extremely aggressive tumor. We report a case of highly aggressive epithelioid hemangioendothelioma and discuss the imaging findings. CT brain plain study revealed a poorly-defined, mixed density expansile and lytic lesion involving the occipital bone with extension to the left side with poorly defined trabecula formation. There was significant but irregular enhancement after intravenous administration of contrast material and also marked bone destruction. Microscopic examination of the fine needle aspiration cytology showed a tumor composed of vascular channels lined by plump endothelial cells, which had enlarged hyperchromatic nuclei. In view of the extensive infiltration the patient was submitted for the radiotherapy.

Osteoid osteoma of the femur: masquerading the tethered cord syndrome

We present an illustrative case of osteoid osteoma of the femur, in an 11 year old male child where the clinical features were masquerading the diagnosis of tethered cord syndrome and lead to the delay in diagnosis.

Diffuerent Locations of Hydatid Cysts: Case Illustrations and Review of Literature

Hydatid disease is a parasitosis caused by Echinococcus granulosus and an important health problem worldwide. Incidental human infestation with larval form results in formation of hydatid cysts in various parts of the body, the liver being the most common site. Peritoneal cavity, spleen, kidney, spinal column, retroperitoneal space, abdominal wall, myocardium, and the thoracic wall are unusually involved.

Simultaneous hemorrhage in intracranial aneurysms and in renal cyst in a case of polycystic kidney disease

We report an unusual case of simultaneous hemorrhage in intracranial aneurysms and in renal cyst in a case of polycystic kidney disease. A 27-year-old gentleman presented with progressive headache and intermittent vomiting of one month duration. Initial computerized tomography (CT) scan and magnetic resonance imaging/angiography revealed a large mass lesion in the right temporal fossa. Over the previous 15 days, he developed progressive weakness in his left upper and lower limbs, and the headache worsened in severity. A repeat of CT scan showed an evidence of aneurysmal bleed and a large temporal lobe hematoma. The patient underwent urgent evacuation of the intracerebral of hematoma and excision of the redundant aneurysmal sac. The patient made excellent recovery in the post-operative period; however, for him, the pain abdomen was persisting. Detailed work-up with contrast-enhanced abdominal CT scan revealed bilateral multiple cysts in the kidneys with evidence of intracystic hemorrhage on the left side. An extensive search of the literature revealed that this kind of presentation has not been reported previously.

Spinal hydatid with meralgia paresthetica in a female: A rare case report.

Meralgia paresthetica presents as tingling sensation in the antero-lateral aspect of thigh. It occurs due to compression of the lateral cutaneous nerve of thigh. Proximal spinal lesions may present as meralgia paresthetica due to radiculopathy. We present a rare case of spinal hydatid with meralgia paresthetica.
