Sagittal sinus thrombosis due to L-asparaginase.

Cerebral Sinovenous Thrombosis (CSVT) is a serious complication of L-asparaginase chemotherapy for leukemia in children. Clinical features of headache, altered consciousness, focal neurological deficit, and seizures developing during or immediately after treatment with L-asparaginase should alert the treating physician to the possibility of CSVT. Immediate imaging of the brain should be done using CT and MRI and the veins should be visualized noninvasively by CT and MR venography.

Giant adrenal myelolipoma: Incidentaloma with a rare incidental association.

Adrenal myelolipoma is an unusual, benign and biochemically inactive tumor that is composed of mature adipose and hematopoietic tissue. It is usually diagnosed accidentally and nowadays much more frequently because of widespread use of ultrasonography, computed tomography (CT) and magnetic resonance imaging. Adrenal myelolipoma is usually unilateral and asymptomatic, though known to be associated with obesity, hypertension, endocrinological disorders and some malignancies.

Pseudoaneurysm of internal mammary artery caused by pulmonary actinomycosis.

Although internal mammary artery pseudoaneurysms are a rare vascular abnormality, they are sometimes seen after sternotomy, diagnostic and therapeutic vascular access or penetrating chest trauma. To our knowledge, internal mammary artery pseudoaneurysm caused by pulmonary actinomycosis has not been reported previously. We report a case of pseudoaneurysm of the left internal mammary artery caused by pulmonary actinomycosis.

Perinephric abscess caused by ruptured retrocecal appendix: MDCT demonstration.

Acute appendicitis may occasionally become extraordinarily complicated and life threatening yet difficult to diagnose. One such presentation is described in a 60-year-old man who was brought to the hospital due to right lumbar pain and fever for the last 15 days. Ultrasonography showed a right perinephric gas and fluid collection.

Head injury caused by tear gas cartridge in teenage population.

Objectives: The aim of this study was to assess the head injury in children caused by an unusual projectile, a tear gas cartridge. The study is the only one on this subject which has been done in a teenage population.

Method: This was a prospective study conducted over a period of 4 years in which all the patients aged less than or equal to 18 years and who had a head injury due to a tear gas cartridge were included.

Listeria monocytogenes meningoencephalitis in an immunocompetent, previously healthy 20-month old female child.

Invasive listeriosis predominantly affects pregnant women, neonates, elderly and people with a compromised immune function. For more than 80 years since the discovery of Listeria in 1924, only a few reports of invasive listeriosis in humans have emerged from India, with all of them in patients having an underlying predisposition. We, however, report Listeria monocytogenes meningoencephalitis in an immunocompetent, previously healthy, 20-month-old female child with no underlying predisposition.

Atypical presentation of lymphangioleiomyomatosis as jugular vein thrombosis.

Lymphangioleiomyomatosis is a rare disorder of unknown origin that almost exclusively affects women of childbearing age. It is characterised by proliferation of abnormal smooth muscle cells (lymphangioleiomyomatosis cells) in the pulmonary interstitium and along the thoracic and abdominal lymphatics. Lymphangioleiomyomatosis may be associated with tuberous sclerosis complex.

Parry-Romberg syndrome associated with unusual intracranial vascular malformations and Phthisis bulbi.

Neurovascular anomalies of Parry-Romberg syndrome have been reported infrequently. We report a case of Parry-Romberg syndrome with hypoplastic left internal carotid, middle cerebral, anterior cerebral, posterior communicating and posterior cerebral artery. The patient presented with partial seizures, hemiparesis and phthisis bulbi.

Popliteal artery embolism by Ascaris lumbricoides: a case report.

Arterial occlusive diseases are highly prevalent and constitute the leading overall cause of death. Adverse events are due to the effects of impaired circulation on critical end organs, namely the brain, heart, abdominal viscera or extremities. Acute thromboembolism remains a major surgical challenge.

Vaginal yolk sac tumor causing infantile hydrometra: use of multidetector-row computed tomography.

Background: A case of vaginal endodermal sinus (yolk sac) tumor resulting in hydrometra in a 9-month-old female infant is reported.

Case: The patient presented with an intermittent bloody discharge on her diapers and a lower abdominal mass on palpation. Multidetector-row computed tomography showed an irregular, dense soft-tissue mass with heterogeneous enhancement within the vagina, obstructing it.

Gluteal pseudophallus in a male child: A rare cutaneous marker of occult spinal dysraphism.

Congenital midline paraspinal cutaneous markers have been practically linked to the location and nature of neural-tissue lesions. One of the most interesting congenital midline paraspinal cutaneous markers has been the human tail in the lumbosacral region, with underlying spinal dysraphism. Human tails have many shapes and sizes and are usually localized to the lumbosacral region.
