AbstractObjective:To assess the efficacy of excision of nasal dermoids through a closed rhinoplasty incision. This is the first description of the use of this approach for excision of superficial nasal dermoids.Methods:Three boys aged five, nine and 12 years presented with midline nasal dermoids with minimal cutaneous involvement. Magnetic resonance imaging demonstrated distinct, cystic, superficial nasal masses. The cysts were excised through a closed rhinoplasty approach. In each case, completeness of extirpation was judged by histopathological examination of the excised specimen. Aesthetic outcome was recorded photographically.Results:All three patients' cysts were completely excised, with excellent cosmetic results.Conclusions:The closed rhinoplasty incision is another approach in the surgeon's armamentarium for excision of small, superficial nasal dermoid cysts. In well selected cases, this approach gives optimal cosmetic results, provides adequate exposure with minimal dissection, and allows total extirpation.

Magnetic Resonance Imaging (MRI) is a widely accessible imaging technique for the detection of brain tumours and cancer, which are further confirmed by histopathological examination. Accurate detection of the tumours and its extent is very difficult. The present study attempted to evaluate the convenience of MRI in detection of different grades of astrocytomas, which are the most commonly occurring brain tumours. This cross-sectional study was conducted at the Department of Radiology and Imaging with the collaboration of Department of Neurosurgery and Department of Pathology at Sir Salimullah Medical College (SSMC & MH), Dhaka from January 2013 to December 2013 for a period of one year. The study population was all the diagnosed cases of intracranial astrocytoma patients regardless of their age and sex. The studied included 48 brain tumour (astrocytoma) patients, ages between 13 and 69 years old. All cases having no contraindication for MRI underwent MR examination followed by histopathological examination of the postoperative resected tissues. The findings of the MRI and histopathological examination were compared to find out the test validity of the MRI findings of the different grades of astrocytoma’s. The highest sensitivity was found in grade III astrocytoma (90.5%) followed by grade II (85.7%) grade IV (75.0%) and grade I (60.0%). The highest specificity was found in grade I astrocytoma (97.7%) followed by Grade III (96.3%), grade IV (92.5%) and grade II (91.5%). The highest accuracy was found in both grade I astrocytoma (93.7%) and grade III (93.7%) followed by grade II (92.5%) and grade IV (89.6%). As per the study findings it can be concluded that,MRI has a high diagnostic accuracy and validity for the detection of different grades of astrocytoma. Bangladesh Med J. 2017 Sep; 46 (3): 85-89

Abstract OBJECTIVE Enterogenous cysts (ECs) of the central nervous system are developmental malformations that occur in the spinal canal, posterior fossa, or cerebral hemispheres. They are usually benign lesions, and malignant transformation is rare. To date, only three cases of malignant transformation have been reported in the literature. We present a case of a cerebellopontine EC showing foci of epithelial dysplasia and malignant transformation into a low-grade papillary mucinous adenocarcinoma. CLINICAL PRESENTATION A 25 year-old man with a 6-year history of hypoacusia presented to our department with facial nerve deficit, visual disturbances, and gait instability. A magnetic resonance imaging scan demonstrated a multiloculated cerebellopontine angle cyst with supratentorial hydrocephalus. INTERVENTION A retrosigmoidal approach was used to achieve cyst removal. This was followed several months later by ventriculoperitoneal shunt placement. The cyst was adherent to the brainstem, cranial nerves, and vessels, and it resembled a thin encapsulated structure filled with mucinous-like substance. No solid component was identified. Histopathological examination revealed an EC with foci of malignant transformation in a mucinous papillary adenocarcinoma. Magnetic resonance imaging was performed 5 months postoperatively due to progressive clinical worsening; this scan revealed lesion recurrence with severe brainstem compression. Emergency surgery was performed, and a large decompression was achieved. Subsequent follow-up computed tomographic scans showed progression of the residual tumor. The patient's neurological condition rapidly worsened, ultimately resulting in death. CONCLUSION The present report suggests that a careful histological examination of all ECs after surgery should be made to exclude dysplastic foci or carcinomatous transformation. Although the clinical behavior of ECs with malignant trasformation is unpredictable, surgery remains the treatment of choice. The use of possible adjuvant chemo- or radiotherapy has not been established.

Longitudinal Observational Study

Introduction: Breast cancer is the most common malignancy in females worldwide. Mammography is a useful tool to diagnose breast cancer. Magnetic Resonance Imaging (MRI) has similar sensitivity like mammography to diagnose breast cancer, however MRI is more sensitive in diagnosing breast cancer in young females and patients with family history of breast cancer. Aim: To compare the sensitivity and specificity of MRI and mammography in the diagnosis of breast cancer. Materials and Methods: This was a longitudinal observational study done in the General Surgery Department of the study institute, from April 2018 to January 2020. Total 228 patients participated in the study. All patients, suspected to have breast cancer clinically, underwent mammography and MRI. The diagnosis was later confirmed by histopathological examination. The sensitivity and specificity of both MRI and mammography were determined by comparing with the results of histopathological examination using student’s t-test. Results: All 228 patients were females. In the study, it was found out that the sensitivity of mammography and MRI was 95% and 95.83%, respectively, in detecting breast cancer. The specificity of mammography and MRI was 89.28% and 83.33%, respectively. However, the differences were statistically non significant. Conclusion: From the study, it was found out that the sensitivity and specificity of MRI and mammography is similar in detecting breast cancer.

Background: The multifocality and multicentrality of breast cancer (MFMCC) are the significant aspects that determine a specialist’s choice between applying breast-conserving therapy (BCT) or performing a mastectomy. This study aimed to assess the usefulness of mammography (MG), contrast-enhanced spectral mammography (CESM), and magnetic resonance imaging (MRI) in women diagnosed with breast cancer before qualifying for surgical intervention to visualize other (additional) cancer foci. Methods: The study included 60 breast cancer cases out of 630 patients initially who underwent surgery due to breast cancer from January 2015 to April 2019. MG, CESM, and MRI were compared with each other in terms of the presence of MFMCC and assessed for compliance with the postoperative histopathological examination (HP). Results: Histopathological examination confirmed the presence of MFMCC in 33/60 (55%) patients. The sensitivity of MG in detecting MFMCC was 50%, and its specificity was 95.83%. For CESM, the sensitivity was 85.29%, and the specificity was 96.15%. For MRI, all the above-mentioned parameters were higher as follows: sensitivity—91.18%; specificity—92.31%. Conclusions: In patients with MFMCC, both CESM and MRI are highly sensitive in the detection of additional cancer foci. Both CESM and MRI change the extent of surgical intervention in every fourth patient.

First Case

A seven-year-old Toy Poodle was presented for progressive ataxia and seizure episodes. Magnetic resonance imaging revealed inflammatory lesions in the cerebrum and brainstem. Management with imatinib mesylate, prednisolone and hydroxyurea were initiated and resulted in complete resolution of the clinical signs. In regular magnetic resonance imaging scans, the overall appearance of the lesions deteriorated but improved again after an increase in the imatinib mesylate dose. The patient had not shown any neurological signs until death and survived for 1052 days after initial presentation. On histopathological examination, the patient was diagnosed with disseminated granulomatous meningoencephalitis involving the cerebrum and brainstem. Immunohistochemical staining was performed on the five types of tyrosine kinase (PDGFR-α, PDGFR-ß, VEGFR-2, c-Kit and c-Abl proteins), which constitute therapeutic targets for conventional multitargeted tyrosine kinase inhibitors. The immunohistochemical analysis revealed that all these tyrosine kinases were expressed in the brain samples. The present report describes the first case of the use of imatinib mesylate therapy for granulomatous meningoencephalitis in the dog. Therapy with imatinib mesylate plus glucocorticoids appears promising as a new therapeutic intervention in meningoencephalitis of unknown aetiology.

Objective The study purpose was to detect the value of magnetic resonance imaging (MRI) compared to computed tomography (CT) and different imaging modalities as conventional radiology in evaluation of sinonasal neoplasms diagnosed by Histopathology. Methods Thirty patients (16 males and 14 females) were complaining of symptoms related to sinonasal tract. After thorough clinical and local examination, the patients were subjected to the following: conventional radiography, CT, MRI, and histopathological examination. Results The nasal cavity was the most commonly involved site with sinonasal malignancies followed by the maxillary sinuses. The least commonly affected site was the frontal sinuses. Benign sinonasal tumors were present in 14 cases. The most common benign lesion was juvenile nasopharyngeal angiofibroma (6 cases), followed by inverted papilloma (3 cases). While malignant sinonasal tumors were present in 16 cases, squamous cell carcinoma was present in 5 cases, and undifferentiated carcinoma, in 3 cases. Lymphoepithelioma and non-Hodgkin lymphomas were present in 2 cases each, while adenocarcinoma, chondrosarcoma, adenoid cystic carcinoma, and rhabdomyosarcoma were present in 1 case each. Conclusion MRI with its superior soft tissue contrast and multiplanar capability is superior to CT in pretreatment evaluation of primary malignant tumors of sinonasal cavity.

Granulosa Cell Tumour (GCT) is a rare malignant ovarian tumour. Adult GCT variety is more common than juvenile variety and occurs usually in postmenopausal women. It showed a spectrum of the imaging findings due to various histological appearances. It may present with solid masses, multilocular cystic lesion or completely cystic lesion. Here, authors present an interesting case of a 27-year-old young female, who presented with a large lump in the abdomen. On Magnetic Resonance Imaging (MRI) there was a large well-defined, multilocular cystic lesion at superior aspect of the lesion and complex cystic, solid mass at inferior aspect. Functional MRI like diffusion weighted imaging which provides good image contrast helped in determining the malignancy despite a benign diagnosis on ultrasound guided biopsy and furthering the patient for histopathological examination to come to a final diagnosis.
