Precision Radiotherapy at high doses require a fixed, referable target point. The frame system fulfills the required criteria by making the target point relocatable and fixed within a stereotactic space. Since December 2001, we have treated 28 central and peripheral nervous system lesions using either radiosurgery as a single high dose fraction or fractionated 3-dimensional conformal radiotherapy using a lower dose and a multi-leaf collimator. Various pathological lesions either benign or malignant were treated. Eighty six percent of our treated lesions showed growth restraint, preventing them from causing new symptoms with a median follow-up duration of 20.5 months. However, the true benefit from this technique would require a long-term follow-up to document the progress.

Calibre persistent submucosal artery of the jejunum: a rare cause of massive gastrointestinal bleeding

Wan Muhaizan WM, Julia MJ, Al Amin D

Malays J Pathol, 2002 Dec;24(2):113-6.

PMID: 12887171

Historically a calibre persistent submucosal artery was most often described in the stomach. However in later years it was also discovered in the duodenum and jejunum. It is an uncommon and important cause of massive gastrointestinal bleeding in which failure of detection and early intervention would lead to death. In this paper we report a 27-year-old man with no significant medical history who presented at the emergency unit for recurrent melaena, haematochezia and hypotension. Initial investigations failed to localize the source of bleeding. Emergency exploratory laporatomy revealed a small jejunal mucosal nodule that was actively spurting blood. Histopathological evaluation identified a calibre persistent submucosal artery.

Dural arteriovenous malformation (DAVM) is relatively rare and defined as abnormal connections or shunts between the arterial and the venous side of vascular tree located within the dura mater. Spontaneous closures of DAVM are rare and have been scarcely reported. This case report will describe the neuroimaging findings and classification of DAVM. A 50 year old lady presented with headache. Neuroimaging showed prominent serpinginous flow-void structures, cerebral angiogram confirmed the presence of DAVM at the occipital region. She had defaulted treatment and follow-up for 3 years. On second admission, she had a cerebral angiogram which showed normal findings with no evidence of fistulas or malformation. She was discharged well. Causes of spontaneous closure of DAVM are discussed.

Pulmonary arteriovenous malformations are rare vascular anomalies. We report a 12-year-old girl who presented with exertional dyspnoea, cyanosis and clubbing since the age of five years, and multiple pulmonary arteriovenous malformations. Computed tomography pulmonary angiogram showed a large pulmonary arteriovenous malformation at the lower lobe of the right lung. Pulmonary angiogram showed a large right lung arteriovenous malformation and two small left lung arteriovenous malformations. The multiple arteriovenous malformations were occluded with Gianturco coils. She is now asymptomatic and on regular follow-up.

PMID: 9058160

Arterio-venous malformation (AVM) of the head of the pancreas is a rare condition that may cause upper gastro-intestinal tract (GIT) bleeding. A 45-year-old man with a large AVM at the pancreato-biliary region is described. The patient had recurrent episodes of hematemesis and melena. Enlargement of the AVM was documented by serial abdominal CT scans performed after each bleed. Whipple procedure was successfully performed in this patient.

MyJurnal

Hereditary Hemorrhagic Telangiectasia, also known as Osler-Weber-Rendu Syndrome is an autosomal
dominant disorder causing systemic abnormalities of the vascular structure. There are multiple arteriovenous malformations present in the skin and mucosal surface of the nail beds, nose, gastrointestinal tract, lungs and brain. Epistaxis is the common presentation symptom, which may require multiple hospital admissions and blood transfusions. It is extremely rare disease in our population. We report 4 cases of HHT who presented to us with moderate to severe epistaxis and how we managed these patients.

Renal arteriovenous malformation (AVM) is a rare congenital anomaly of the urinary system. We present a patient with bilateral renal AVMs who presented with back pain and microscopic hematuria. This case highlights the importance of careful diagnostic work-up in the evaluation of upper tract hematuria. Renal AVM was found to be the cause of mild back pain and persistent microscopic hematuria in a 45-year-old lady. This case highlights the importance of complete diagnostic work-up in the evaluation of microscopic hematuria in arriving at the correct diagnosis of an uncommon clinical entity.

PMID: 19296018

Congenital coronary artery anomalies are rare, with an incidence of about 0.06-1.3 percent of all patients undergoing cardiac catheterisation. They are commonly asymptomatic, but potentially serious lesions may lead to myocardial ischaemia, infarction and/or sudden cardiac death. The occurrence of a concomitant stenotic lesion is exceedingly rare. We report an 80-year-old man who presented with acute anterior myocardial infarction. Coronary angiography revealed severe proximal left anterior descending (LAD) and arteriovenous malformation (AVM) from the first septal branch of the LAD. The LAD stenosis and the AVM were successfully treated with two Jomed covered stents.

Nawawi O, Sinnasamy M, Ramli N

Br J Radiol, 2006 Jul;79(943):e12-5.

PMID: 16823046

A case of an intracerebral bleed in a young man with a rare combination of arteriovenous malformation (AVM) and unilateral moyamoya disease is presented. The location of the bleed in the left basal ganglia corresponded to the area supplied by the basal moyamoya vessels. The AVM which received supply from collateral moyamoya vessels as well as normal cerebral arteries was located in the ipsilateral parieto-occipital region posterior to the basal ganglia bleed. This is the first reported cerebral AVM co-existing with a unilateral moyamoya disease in the English literature. Unusual features of the case such as the unilaterality of the angiographic abnormalities, their coexistence and hypotheses as to their development are discussed.

PMID: 30846675

Acute massive haemothorax is a life-threatening situation, which is often associated with a preceding trauma. However, spontaneous haemothorax is a rare occurrence, especially in pregnancy. Spontaneous haemothorax in the immediate post-partum period secondary to a ruptured intercostal AVM is extremely rare more so in the background of an undiagnosed neurofibromatosis. This is a report of a young lady presenting with pleuritis and breathlessness after the delivery of her 1st child. Her management is discussed.

PMID: 23533876 DOI: 10.1155/2013/158961

Aim. To report a rare case of arteriovenous malformation in temporal lobe presenting as contralateral orbital symptoms mimicking carotid-cavernous fistula. Method. Interventional case report. Results. A 31-year-old Malay gentleman presented with 2-month history of painful progressive exophthalmos of his left eye associated with recurrent headache, diplopia, and reduced vision. Ocular examination revealed congestive nonpulsating 7 mm exophthalmos of the left eye with no restriction of movements in all direction. There was diplopia in left lateral gaze. Left IOP was elevated at 29 mmHg. Left eye retinal vessels were slightly dilated and tortuous. CT scan was performed and showed right temporal arteriovenous malformation with a nidus of 3.8 cm × 2.5 cm with right middle cerebral artery as feeding artery. There was dilated left superior ophthalmic vein of 0.9 mm in diameter with enlarged left cavernous sinus. MRA and carotid angiogram confirmed right temporal arteriovenous malformation with no carotid-cavernous fistula. Most of the intracranial drainage was via left cavernous sinus. His signs and symptoms dramatically improved following successful embolisation, completely resolved after one year. Conclusion. Intracranial arteriovenous malformation is rarely presented with primary ocular presentation. Early intervention would salvage the eyes and prevent patients from more disaster morbidity or fatality commonly due to intracranial haemorrhage.

Fulltext Development of pseudo-subarachnoid hemorrhage secondary to hypoxic-ischemic injury due to bleeding pulmonary arterio-venous malformation

Md Noh MSF, Abdul Rashid AM

BMC Neurol, 2018 Sep 28;18(1):157.

PMID: 30266082 DOI: 10.1186/s12883-018-1161-x

BACKGROUND: The computed tomography (CT) finding of a pseudo-subarachnoid hemorrhage (SAH) may lead the treating physician into a diagnostic dilemma. We present a case of a pseudo-SAH in a patient with post-resuscitative encephalopathy, secondary to a newly diagnosed bleeding pulmonary arterio-venous malformation (AVM).

CASE PRESENTATION: A 19-year-old female presented acutely with massive hemoptysis. Cardiopulmonary resuscitation (CPR) followed, and the patient was subsequently intubated for airway protection with intensive care unit (ICU) admission. Urgent CT angiography of the thorax showed a bleeding pulmonary AVM, with evidence of hemothorax. Non-contrasted cranial CT initially revealed cerebral edema. Day 3 post admission, repeat cranial CT showed worsening cerebral edema, with evidence of pseudo-SAH. Patient passed away the next day.

CONCLUSIONS: Pseudo-SAH, if present, carries a poor prognosis. It should be recognized as a potential CT finding in patients with severe cerebral edema, due to various causes. The diagnosis is vital, to avoid wrongful treatment institution, as well as determination of cause of death.

Arteriovenous malformations are congenital lesions that may evolve with time and manifest in a plethora of presentations. They can occur as torrential epistaxis when it extensively involves the facial region. Multi-imaging modalities are available to assist in characterizing the structure of the lesion as well as its location and extent. This complex disease requires a multidisciplinary team approach with preoperative embolization and surgery. We present a rare cause of life-threatening epistaxis in a gentleman with a longstanding orbital and hemifacial arteriovenous malformation and discuss the complexities involved in its management.

Medicine & Health, 2019;14(2):261-265.

MyJurnal

Cavernous lymphangioma is a congenital malformation of lymphatic system causing dilated lymphatic sinuses that involve the skin and subcutaneous tissues. This was an interesting case of dystrophic macrodactyly of the left ring and little finger in a 18-month-old girl who presented with swollen and sausage like fingers deformity which turned out to be an isolated cavernous lymphangioma. This tumor, although rare to occur in the extremeties, must be differentiated from other congenital vascular lesions of the hand that include arteriovenous malformations and hemangiomas. Diagnosis should be solely based on histopathological analysis of the excised tissue mass. Surgical excision is usually necessary for satisfactory functional and cosmetic outcome

JUMMEC, 2018;21(2):31-34.

MyJurnal

Phenytoin is commonly prescribed for the prophylaxis of seizures in neurosurgical patients. A phenytoininduced
serious adverse effect of thrombocytopenia has been reported in the literature. The concurrent
use of dexamethasone, another commonly prescribed drug in neurosurgical patients, has been reported to
aggravate this adverse haematological effect. We present a report of phenytoin-induced thrombocytopenia
in a patient concurrently prescribed with dexamethasone, after an intracerebral haemorrhage secondary to
a rupture of an arteriovenous malformation. The thrombocytopenia was noted after two weeks of phenytoin
medication. Phenytoin was immediately withheld, and seven units of random donor platelets were transfused.
A gradual resolution of thrombocytopenia was observed within a week.

Haemorrhage arising from gastric arteriovenous malformation (AVM) is rare and normally occurs in the elderly. Bleeding gastric AVM presenting in the younger age group is even rarer. We report a case of a 14 year old boy who presented with recurrent episodes of haematemesis. He subsequently underwent a proximal gastrectomy and the histological examination confirmed a gastric AVM. After reviewing the literature we believe this is the youngest ever reported case of bleeding gastric AVM reported in English literature.
