Case report: Multiple intracranial hydatid cysts with post-operative dissemination
(1991) S.K. Gupta; S.C. Tandon; S. Khanna; S. Asthana
A case of primary multiple intracranial hydatid cysts is reported. The cysts were both supratentorial and infratentorial. One showed rim enhancement and perifocal oedema. Post-operatively, the number and size of cysts increased, possibly because of intraoperative rupture. © 1991 The Royal College of Radiologists. All rights reserved.
Gunshot vertebro-internal jugular fistula
(1982) S.C. Tandon; S.K. Gupta; A. Srivastava
A post-gunshot injury, vertebro-internal jugular vein fistula (at the C1 level) in a 38-year-old male is reported. After sustaining a gunshot injury in the cranio-cervical region, the patient developed quadriplegia and 12th nerve palsy. With conservative management, he continued to improve neurologically. Six months after the injury, he developed an arterio-venous fistula between the vertebral venous plexus and the branches of the external carotid artery. It was successfully treated by external carotid artery ligation. He remained symptom-free for nine months when he again developed vertebro-internal jugular vein fistula, documented angiographically. The patient refused surgery. Diagnostic and therapeutic aspects of vertebral arterio-venous fistulae are reviewed.
Intracerebral cystic epidermoid - Report of two cases
(Springer-Verlag, 1981) S. Mohanty; R.N. Bhattacharya; S.C. Tandon; P.K. Shukla
Two cases of intracerebral epidermoid cysts are reported. Their presentation did not conform with classical symptoms and signs. Total excision was followed by complete recovery. © 1981 Springer-Verlag.
Intramedullary neurofibroma of the cervical spinal cord: Case report with review of the literature
(1984) R. Sharma; S.C. Tandon; S. Mohanty; S. Gupta
A case of cervical intramedullary neurofibroma diagnosed and surgically treated is reported. This patient, a 27-year-old man, had no evidence of von Recklinghausen's disease. The case is discussed, and a review of literature is presented.
Multiple intracranial tuberculomas: A case report
(1989) V.D. Tiwari; S. Mohanty; S.C. Tandon
An eleven year old girl was admitted with clinical features of severe rise of intracranial pressure, brain stem dysfunction and acute abdominal pain. C.T. Scan of head revealed 34 tuberculomas spread in all parts of the brain. She made complete recovery on antituberculous treatment and C.T. after one year showed complete disappearance of all tuberculomas.
Radiation therapy for symptomatic vertebral haemangioma
(1990) A.K. Asthana; S.C. Tandon; G.C. Pant; A. Srivastava; S. Pradhan
Vertebral haemangiomas are slowly growing benign tumours and are usually asymptomatic. They rarely cause symptoms and signs related to cord compression. Larger lesions create significant problems during surgery because of haemorrhage and vascular supply crucial to spinal cord function. In such severely symptomatic vertebral haemangiomas, radiation therapy has been tried and good results obtained, especially in terms of good functional recovery. We have treated 17 patients (including nine paraplegic patients) with radiotherapy (Co-60). Treatment was given by single posterior field, encompassing the involved area with a dose of 35-40 Gy in 3 to 4 weeks (five fractions per week). All patients with pain and tenderness were relieved completely (87.5%) or partially (12.5%). Similarly patients with numbness and paresis showed either complete (66.7%) or partial response (33.3%) from symptoms on follow-up. Out of nine paraplegic patients six (66.6%) had recovered competely, one (11.2%) partially and two (22.2%) had no response. The two patients who did not show any marked relief, had paraplegia of longer duration (more than 6 months). Our study indicates that severely symptomatic vertebral haemangioma can be successfully treated by radiation therapy and it can be chosen as first line of treatment with an optimum dose of 35-40 Gy in 3 to 4 weeks. © 1990 The Royal College of Radiologists.
Right Brain Damage Impairs Recognition of Negative Emotions
(1991) M.K. Mandal; S.C. Tandon; H.S. Asthana
Patients with right or left hemisphere-damage and normal control groups were asked to judge facial emotions from photographs presented in two orientations — upright, inverted. Responses were elicited with a matching and a verbal labelling task. Normal controls were significantly superior in the judgment of facial emotions than left hemisphere-damaged patients, who in turn were significantly superior than right hemisphere-damaged patients. Negative-aroused (fear, anger) and negative-nonaroused (sadness, disgust) facial expressions were recognized with significantly greater accuracy by left hemisphere-damaged patients compared to right hemisphere-damaged patients; the group difference in performance was nonsignificant for positive (happiness, surprise) emotions. © 1991, Masson Italia Periodici s.r.l.

Role of cerebral hemispheres and regions in processing hemifacial expression of emotion: Evidence from brain-damage
(Informa Healthcare, 1992) M.K. Mandal; H.S. Asthana; S.C. Tandon; S. Asthana
Patients with focal brain-damage, right or left hemisphere-damage (RHD/LHD) and anterior or posterior region-damage (ARD/PRD), and normal controls (NC) were asked to match the photographs of (left-right) hemifacial expressions of emotions, positive (happy-surprise), negative-aroused (fear-anger), neg-ative-nonaroused (sad-disgust). Findings indicated that (a) NC subjects were significantly superior to brain-damaged patients; the difference between RHD and LHD patients was nonsignificant, and (b) ARD patients were significantly inferior to PRD patients who, in turn, were significantly inferior to NC subjects, in the perceptual matching task with hemifacial affective stimuli. © 1992 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
Unusual presentation of tuberculous brain abscess
(1992) S.C. Tandon; S. Asthana; S. Mohanty
Two cases of an unusual manifestation of tuberculous brain abscess are presented. One had a large cold abscess with underlying osteomyelitis and the other had a multilocular abscess in frontal lobe. Both were managed with surgical intervention along with anti-tuberculosis chemotherapy. There was no recurrence.
