Background: Spontaneous intraparenchymal haemorrhage (IPH) is the bleeding within brain parenchyma in absence of any kind of trauma or surgery. Spontaneous IPH is serious disabling and deadly one; of all strokes. The most common site of insult is still enigmatic. The reason of our study is to find out the most involved area of brain of spontaneous IPH. Materials & Methods: Our study is prospective type of study. Total 48 numbers of patients were diagnosed as spontaneous intraparenchymal haemorrhage and have first time been reported & admitted in Combined Military Hospital (CMH) Dhaka, between July 2021 and Jan 2022. All of our patients were randomly allocated and sampled as per inclusion and exclusion criteria. Diagnosis was done based upon details history, through clinical examination and releavant investigation. Computed Tomography (CT) scan (non-contrast) of brain was done to authinticate diagnosis and to define site of lesion as well. Data of our study collected by specially designed questionnaire and analyses of statistics was done by Statistical Package for Social Sciences version 26 for Windows (SPSS). Results: In this study 48 cases were finally selected as ‘Spontaneous IPHs’. All of them were diagnosed clinically and confirmed by Computed Tomography scan. In this study, it was revealed that most of the patients were male 37 (77.08%) and female only 11(22.92%) in number. Concerning distribution of age; old age (≥ 60 years) affected 28 (58.33%) than young adult (18-25 years) only 1 (2.08%) in number. It was observed that out of 48 patients; HTN alone 50% (24); next Mixed pathology 16.67% (8) (HTN, Amyloid angiopathy, Coagulopathy, Tumour etc.), then Idiopathic 8.33% (4). In regard to site & side of involvement of IPHs; it was noticed that basal ganglia is more affected 33 in number specially left alone 41.67%, and dominant (left) cerebral hemisphere is more frequent 23( 47.92%) than opposite right (non-dominant) hemisphere 17 (35.42%). Conclusion: Basal ganglia is supplied by a little beat peculier lenticulostriate artey, which is right angle, narrow, end artey and induce atherosclerotic microaneurysm; prone to rupture. Dominant cerebral hemisphere (usually left) is highly metabolically active with having raised blood flow; and highest incidence of IPH is at Basal ganglia of Dominant hemisphere.

Background: Spontaneous Intracerebral Haemorrhage (ICH) may be defined as it is the bleeding within brain tissue in absence of trauma or surgery. Usually it occur lesser than ischemic stroke but is much higher disabling and deadly than all types of stroke. Although adult age is more susceptible than younger age; but incidence in very older group is still ambiguous. The purpose of this study is to observe spontaneous ICHs in various age group specially in very old age. Methods: A total 186 patients were diagnosed as spontaneous haemorrhagic stroke and they have been first time reported & admitted in Combined Military Hospital (CMH) Dhaka, between January 2018 and October 2019. Diagnosis was based upon details history, meticulous clinical examination and finally confirmed by non-contrast Computed Tomography (CT) scan of brain. Statistical analyses were performed by using Statistical Package for Social Sciences (SPSS) version 26. Results: Total 186 patients were admitted in CMH Dhaka from Jan 2018- Oct 2019 and selected for our study who full-fill the criteria. Male patients were 137(73.66%), female 49(26.34%) and aged 18 years and above. There is remarkable relationship of spontaneous intracerebral haemorrhage with the age variables. Rate of spontaneous ICH among age group, ≥25 – 74 years, 175(94.08%) whereas ˂25 years only 1(.54%) and 75-79 years 8(4.30%) and ≥80 years 2(1.08%) patients. So raising age like middle and old age affected much 183(98.38%) but very old age is less affected only 2(1.08%) patients. Regarding aetilogy of spontaneous ICHs of 186 patients, Hypertensive 124(66.67%), Coagulopathy 16(8.60%), Amyloid angiopathy 14(7.53%), Idiopathic 12(6.45%) and hypertension is most common association. Conclusion: Hypertension, coagulopathies are most risk factors of ICHs. Advancement of age of patients are more susceptible to haemorrhagic stroke but very old age is less vulnerable to spontaneous ICH.
